F5 Predicts: Education gets personal
The topic of education is taking centre stage today like never before. I think we can all agree that education has come a long way from the days where students and teachers were confined to a classroom with a chalkboard. Technology now underpins virtually every sector and education is no exception. The Internet is now the principal enabling mechanism by which students assemble, spread ideas and sow economic opportunities. Education data has become a hot topic in a quest to transform the manner in which students learn. According to Steven Ross, a professor at the Centre for Research and Reform in Education at Johns Hopkins University, the use of data to customise education for students will be the key driver for learning in the future[1].This technological revolution has resulted in a surge of online learning courses accessible to anyone with a smart device. A two-year assessment of the massive open online courses (MOOCs) created by HarvardX and MITxrevealed that there were 1.7 million course entries in the 68 MOOC [2].This translates to about 1 million unique participants, who on average engage with 1.7 courses each. This equity of education is undoubtedly providing vast opportunities for students around the globe and improving their access to education. With more than half a million apps to choose from on different platforms such as the iOS and Android, both teachers and students can obtain digital resources on any subject. As education progresses in the digital era, here are some considerations for educational institutions to consider: Scale and security The emergence of a smogasborad of MOOC providers, such as Coursera and edX, have challenged the traditional, geographical and technological boundaries of education today. Digital learning will continue to grow driving the demand for seamless and user friendly learning environments. In addition, technological advancements in education offers new opportunities for government and enterprises. It will be most effective if provided these organisations have the ability to rapidly scale and adapt to an all new digital world – having information services easily available, accessible and secured. Many educational institutions have just as many users as those in large multinational corporations and are faced with the issue of scale when delivering applications. The aim now is no longer about how to get fast connection for students, but how quickly content can be provisioned and served and how seamless the user experience can be. No longer can traditional methods provide our customers with the horizontal scaling needed. They require an intelligent and flexible framework to deploy and manage applications and resources. Hence, having an application-centric infrastructure in place to accelerate the roll-out of curriculum to its user base, is critical in addition to securing user access and traffic in the overall environment. Ensuring connectivity We live in a Gen-Y world that demands a high level of convenience and speed from practically everyone and anything. This demand for convenience has brought about reform and revolutionised the way education is delivered to students. Furthermore, the Internet of things (IoT), has introduced a whole new raft of ways in which teachers can educate their students. Whether teaching and learning is via connected devices such as a Smart Board or iPad, seamless access to data and content have never been more pertinent than now. With the increasing reliance on Internet bandwidth, textbooks are no longer the primary means of educating, given that students are becoming more web oriented. The shift helps educational institutes to better personalise the curriculum based on data garnered from students and their work. Duty of care As the cloud continues to test and transform the realms of education around the world, educational institutions are opting for a centralised services model, where they can easily select the services they want delivered to students to enhance their learning experience. Hence, educational institutions have a duty of care around the type of content accessed and how it is obtained by students. They can enforce acceptable use policies by only delivering content that is useful to the curriculum, with strong user identification and access policies in place. By securing the app, malware and viruses can be mitigated from the institute’s environment. From an outbound perspective, educators can be assured that students are only getting the content they are meant to get access to. F5 has the answer BIG-IP LTM acts as the bedrock for educational organisations to provision, optimise and deliver its services. It provides the ability to publish applications out to the Internet in a quickly and timely manner within a controlled and secured environment. F5 crucially provides both the performance and the horizontal scaling required to meet the highest levels of throughput. At the same time, BIG-IP APM provides schools with the ability to leverage virtual desktop infrastructure (VDI) applications downstream, scale up and down and not have to install costly VDI gateways on site, whilst centralising the security decisions that come with it. As part of this, custom iApps can be developed to rapidly and consistently deliver, as well as reconfigure the applications that are published out to the Internet in a secure, seamless and manageable way. BIG-IP Application Security Manager (ASM) provides an application layer security to protect vital educational assets, as well as the applications and content being continuously published. ASM allows educational institutes to tailor security profiles that fit like a glove to wrap seamlessly around every application. It also gives a level of assurance that all applications are delivered in a secure manner. Education tomorrow It is hard not to feel the profound impact that technology has on education. Technology in the digital era has created a new level of personalised learning. The time is ripe for the digitisation of education, but the integrity of the process demands the presence of technology being at the forefront, so as to ensure the security, scalability and delivery of content and data. The equity of education that technology offers, helps with addressing factors such as access to education, language, affordability, distance, and equality. Furthermore, it eliminates geographical boundaries by enabling the mass delivery of quality education with the right policies in place.

F5 Synthesis: Keeping the licensing creep out of expanding software options
(Editors note: the LineRate product has been discontinued for several years. 09/2023) --- One of the funny things about infrastructure moving toward a mix of hardware and software (virtual or traditional) is that the issues that plague software come with it. Oh, maybe not right away, but eventually they crawl out of the deep recesses of the data center like a Creeper in Minecraft and explode on the unsuspecting adventurer, er, professional. While licensing network infrastructure has never been painless, it's never been as complicated or difficult as its software counterparts simply due to the sheer magnitude of difference between the number of network boxes under management and the number of software applications and infrastructure under management. That is changing. Rapidly. Whether it's because of expanding cloud footprints or a need to support microservices and highly virtualized environments, the reality is that the volume of software-based infrastructure is increasing. Like its application counterparts, that means licensing challenges are increasing too. That means We (that's the corporate F5 "we") have to change, too. As we continue to expand the software offerings available for F5 Synthesis beyond cloud and virtualization, we need to also adjust licensing options. That means staying true to the Synthesis tenet of Simplified Business Models. That's why we're making not one but two announcements at the same time. The first is the expansion of existing software options for F5 Synthesis. In addition to cloud-native and virtual editions of BIG-IP, we're making available a lightweight, load balancing service - LineRate Point. LineRate Point complements existing Synthesis services by supporting more directly the needs of application and operations teams for agile, programmable application-affine services in the data center or in the cloud, on- and off-premise. This is a missing component as the data center architecture bifurcates into a shared, core network and an app specific (business) network. Whether it's a focus on moving toward Network Service Virtualization or a need to deploy on a per-app / per-service basis thanks to microservices or increasing mobile application development, LineRate Point offers the scale and security necessary without compromising on the agility or programmability required to fit into the more volatile environment of the growing application network. But a sudden explosion of LineRate Point (or any service, really) anyway across the potential deployment spectrum would create the same kind of tracking and management headaches experienced by software infrastructure and applications. Licensing becomes a nightmare, particularly when instances might be provisioned and terminated on a more frequent basis than is typical for most network-deployed services. So along with the introduction of LineRate Point we're also bringing to F5 Synthesis Volume License Subscriptions (VLS). VLS holds true to the tenet of simplified business models both by offering F5 Synthesis software options (VE, cloud and LineRate Point) with a licensing model that fits the more expansive use of these services to support microservices, cloud and virtualization. VLS brings to F5 Synthesis the ability to support the migration of service infrastructure closer to the applications it is supporting without sacrificing the need for management and licensing. VLS also simplifies a virtual-based Synthesis High Performance Service Fabric by centralizing licensing of large numbers of virtual BIG-IP instances (VE) and simplifying the process. According to a 2014 InformationWeek survey on software licensing, nearly 40% of organizations have a dedicated resource who spends more than 50% of their time managing licenses and subscriptions. Moving to a more software-focused approach for infrastructure services will eventually do the same if it's not carefully managed from the start. By taking advantage of F5 Synthesis Simplified Business Models and its VLS offering, organizations can avoid the inevitable by bringing a simplified licensing strategy along with their software-based service infrastructure. You can learn more about F5 Synthesis Simplified Business Models by following Alex Rublowsky, Senior Director of Licensing Business Models, here on DevCentral as he shares more insight into the growing licensing options available for F5's expanding software portfolio.
F5 in AWS Part 4 - Orchestrating BIG-IP Application Services with Open-Source tools
Updated for Current Versions and Documentation Part 1 : AWS Networking Basics Part 2: Running BIG-IP in an EC2 Virtual Private Cloud Part 3: Advanced Topologies and More on Highly-Available Services Part 4: Orchestrating BIG-IP Application Services with Open-Source Tools Part 5: Cloud-init, Single-NIC, and Auto Scale Out of BIG-IP in v12 The following post references code hosted at F5's Github repository f5networks/aws-deployments. This code provides a demonstration of using open-source tools to configure and orchestrate BIG-IP. Full documentation for F5 BIG-IP cloud work can be found at Cloud Docs: F5 Public Cloud Integrations. So far we have talked above AWS networking basics, how to run BIG-IP in a VPC, and highly-available deployment footprints. In this post, we’ll move on to my favorite topic, orchestration. By this point, you probably have several VMs running in AWS. You’ve lost track of which configuration is setup on which VM, and you have found yourself slowly going mad as you toggle between the AWS web portal and several SSH windows. I call this ‘point-and-click’ purgatory. Let's be blunt, why would you move to cloud without realizing the benefits of automation, of which cloud is a large enabler. If you remember our second article, we mentioned CloudFormation templates as a great way to deploy a standardized set of resources (perhaps BIG-IP + the additional virtualized network resources) in EC2. This is a great start, but we need to configure these resources once they have started, and we need a way to define and execute workflows which will run across a set of hosts, perhaps even hosts which are external to the AWS environment. Enter the use of open-source configuration management and workflow tools that have been popularized by the software development community. Open-source configuration management and AWS APIs Lately, I have been playing with Ansible, which is a python-based, agentless workflow engine for IT automation. By agentless, I mean that you don’t need to install an agent on hosts under management. Ansible, like the other tools, provides a number of libraries (or “modules”) which provide the ability to manage a diverse collection of remote systems. These modules are typically implemented through the use of API calls, often over HTTP. Out of the box, Ansible comes with several modules for managing resources in AWS. While the EC2 libraries provided are useful for basic orchestration use cases, we decided it would be easier to atomically manage sets of resources using the CloudFormation module. In doing so, we were able to deploy entire CloudFormation stacks which would include items like VPCs, networking elements, BIG-IP, app servers, etc. Underneath the covers, the CloudFormation: Ansible module and our own project use the python module to interact with AWS service endpoints. Ansible provides some basic modules for managing BIG-IP configuration resources. These along with libraries for similar tools can be found here: Ansible Puppet SaltStack In the rest of this post, I’ll discuss some work colleagues and I have done to automate BIG-IP deployments in AWS using Ansible. While we chose to use Ansible, we readily admit that Puppet, Chef, Salt and whatever else you use are all appropriate choices for implementing deployment and configuration management workflows for your network. Each have their upsides and downsides, and different tools may lend themselves to different use cases for your infrastructure. Browse the web to figure out which tool is right for you. Using Standardized BIG-IP Interfaces Speaking of APIs, for years F5 has provided the ability to programmatically configure BIG-IP using iControlSOAP. As the audiences performing automation work have matured, so have the weapons of choice. The new hot ticket is REST (Representational State Transfer), and guess what, BIG-IP has a REST interface (you can probably figure out what it is called). Together, iControlSOAP and iControlREST give you the power to manage nearly every configuration element and feature of BIG-IP. These interfaces become extremely powerful when you combine them with your favorite open-source configuration management tool and a cloud that allows you to spin up and down compute and networking resources. In the project described below, we have also made use of iApps using iControlRest as a way to create a standard virtual server configuration with the correct policies and profiles. The documentation in Github describes this in detail, but our approach shows how iApps provide a strongly supported approach for managing network policy across engineering teams. For example, imagine that a team of software engineers has written a framework to deploy applications. You can package the network policy into iApps for various types of apps, and pass these to the teams writing the deployment framework. Implementing a Service Catalog To pull the above concepts together, a colleague and I put together the aws-deployments project.The goal was to build a simple service catalog which would enable a user to deploy a containerized application in EC2 with BIG-IP network services sitting in front. This is example code that is not supported by F5 support but is a proof of concept to show how you can fully automate production-like deployments in AWS. Some highlights of the project include: Use of iControlRest and iControlSoap within Ansible playbooks to setup advanced topologies of BIG-IP in AWS. Automated deployment of a basic ASM web application firewall policy to protect a vulnerable web app (Hackazon. Use of iApps to manage virtual server configurations, including the WAF policy mentioned above. Figure 1 - Generic Architecture for automating application deployments in public or private cloud In examination of the code, you will see that we provide the opportunity to provision all the development models outlined in our earlier post (a single standalone VE, standalones BIG-IP VEs striped availability zones, clusters within an availability zone, etc). We used Ansible and the interfaces on BIG-IP to orchestrate the workflows assoiated with these deployment models. To perform the clustering step, we have used the iControlSoap interface on BIG-IP. The final set of technology used is depicted in Figure 3. Figure 2 - Technologies used in the aws-deployments project on Github Read the Code and Test It Yourself All the code I have mentioned is available at f5networks/aws-deployments. We encourage you to download and run the code for yourself. Instructions for setting up a development environment which includes the necessary dependencies is easy. We have packaged all the dependencies for use with either Vagrant or Docker as development tools. The instructions for either of these approaches can be found in the README.md or in the /docs directory. The following video shows an end-to-end usage example. (Keep in mind that the code has been updated since this video was produced). At the end of the day, our goal for this work was to collect customer feedback. Please provide some by leaving a comment below, or by filing ‘pull requests’ or ‘issues’ in Github. In the next few weeks, we will be updating the project to include the Hackazon app mentioned above, show how to cluster BIG-IP across availability zones, and how to deploy an ASM profile with an iApp. Have fun!
F5 in AWS Part 5 - Cloud-init, Single-NIC, and Auto Scale Out in BIG-IP
Updated for Current Versions and Documentation Part 1 : AWS Networking Basics Part 2: Running BIG-IP in an EC2 Virtual Private Cloud Part 3: Advanced Topologies and More on Highly-Available Services Part 4: Orchestrating BIG-IP Application Services with Open-Source Tools Part 5: Cloud-init, Single-NIC, and Auto Scale Out of BIG-IP in v12 The following article covers features and examplesin the 12.1 AWS Marketplace release, discussed in the following documentation: Amazon Web Services: Single NIC BIG-IP VE Amazon Web Services: Auto Scaling BIG-IP VE You can find the BIG-IP Hourly and BYOL releases in the Amazon marketplace here. BIG-IP utility billing images are available, which makes it a great time to talk about some of the functionality. So far in Chris’s series, we have discussed some of the highly-available deployment footprints of BIG-IP in AWS and how these might be orchestrated. Several of these footprints leverage BIG-IP's Device Service Clustering (DSC) technology for configuration management across devices and also lend themselves to multi-app or multi-tenant configurations in a shared-service model. But what if you want to deploy BIG-IP on a per-app or per-tenant basis, in a horizontally scalable footprint that plays well with the concepts of elasticity and immutability in cloud? Today we have just the option for you. Before highlighting these scalable deployment models in AWS, we need to cover cloud-init and single-NIC configurations; two important additions to BIG-IP that enable an Auto Scaling topology. Elasticity Elastiity is obviously one of the biggest promises/benefits of cloud. By leveraging cloud, we are essentially tapping into the "unlimited" (at least relative to our own datacenters) resources large cloud providers have built. In actual practice, this means adopting new methodologies and approaches to truely deliver this. Immutablity In traditional operational model of datacenters, everything was "actively" managed. Physical Infrastructure still tends to lend itself to active management but even virtualized services and applications running on top of the infrastructure were actively managed. For example, servers were patched, code was live upgraded inplace, etc. However, to achieve true elasticity, where things are spinning up or down and more ephemeral in nature, it required a new approach. Instead of trying to patch or upgrade individual instances, the approach was treating them as disposable which meant focusing more on the build process itself. ex. Netflix's famous Building with Legos approach. Yes, the concept of golden images/snapshots existed since virtualization but cloud, with self-service, automation and auto scale functionality, forced this to a new level. Operations focus shifted more towards a consistent and repeatable "build" or "packaging" effort, with final goal of creating instances that didn't need to be touched, logged into, etc. In the specific context of AWS's Auto Scale groups, that means modifying the Auto Scale Group's "launch config". The steps for creating the new instances involve either referencing an entirely new image ID or maybe modification to a cloud-init config. Cloud-init What is it? First, let’s talk about cloud-init as it is used with most Linux distributions. Most of you who are evaluating or operating in the cloud have heard of it. For those who haven’t, cloud-init is an industry standard for bootstrapping machines at startup. It provides a simple domain specific language for common infrastructure provisioning tasks. You can read the official docs here. For the average linux or systems engineer, cloud-init is used to perform tasks such as installing a custom package, updating yum repositories or installing certificates to perform final customizations to a "base" or “golden” image. For example, the Security team might create an approved hardened base image and various Dev teams would use cloud-init to customize the image so it booted up with an ‘identity’ if you will – an application server with an Apache webserver running or a database server with MySQL provisioned. Let’s start with the most basic "Hello World" use of cloud-init, passing in User Data (in this case a simple bash script). If launching an instance via the AWS Console, on the Configure Instance page, navigate down the “Advanced Details”: Figure 1: User Data input field - bash However, User Data is limited to < 16KBs and one of the real powers of cloud-init came from extending functionality past this boundry and providing a standardized way to provision, or ah humm, "initialize" instances.Instead of using unwieldy bash scripts that probed whether it was an Ubuntu or a Redhat instance and used this OS method or that OS method (ex. use apt-get vs. rpm) to install a package, configure users, dns settings, mount a drive, etc. you could pass a yaml file starting with #cloud-config file that did a lot of this heavy lifting for you. Figure 2: User Data input field - cloud-config Similar to one of the benefits of Chef, Puppet, Salt or Ansible, it provided a reliable OS or distribution abstraction but where those approaches require external orchestration to configure instances, this was internally orchestrated from the very first boot which was more condusive to the "immutable" workflow. NOTE: cloud-init also compliments and helps boot strap those tools for more advanced or sophisticated workflows (ex. installing Chef/Puppet to keep long running non-immutable services under operation/management and preventing configuration drift). This brings us to another important distinction. Cloud-init originated as a project from Canonical (Ubuntu) and was designed for general purpose OSs. The BIG-IP's OS (TMOS) however is a highly customized, hardened OS so most of the modules don't strictly apply. Much of the Big-IP's configuration is consumed via its APIs (TMSH, iControl REST, etc.) and stored in it's database MCPD. We can still achieve some of the benefits of having cloud-init but instead, we will mostly leverage the simple bash processor. So when Auto Scaling BIG-IPs, there are a couple of approaches. 1) Creating a custom image as described in the official documentation. 2) Providing a cloud-init configuration This is a little lighter weight approach in that it doesn't require the customization work above. 3) Using a combination of the two, creating a custom image and leveraging cloud-init. For example, you may create a custom image with ASM provisioned, SSL certs/keys installed, and use cloud-init to configure additional environment specific elements. Disclaimer: Packaging is an art, just look at the rise of Docker and new operating systems. Ideally, the more you bake into the image upfront, the more predictable it will be and faster it deploys. However, the less you build-in, the more flexible you can be. Things like installing libraries, compiling, etc. are usually worth building in the image upfront. However, the BIG-IP is already a hardened image and things like installing libraries is not something required or recommended so the task is more about addressing the last/lighter weight configuration steps. However, depending on your priorities and objectives,installing sensitive keying material, setting credentials, pre-provisioning modules, etc. might make good candidates for investing in building custom images. Using Cloud-init with CloudFormation templates Remember when we talked about how you could use CloudFormation templates in a previous post to setup BIG-IP in a standard way? Because the CloudFormation service by itself only gave us the ability to lay down the EC2/VPC infrastructure, we were still left with remaining 80% of the work to do; we needed an external agent or service (in our case Ansible) to configure the BIG-IP and application services. Now, with cloud-init on the BIG-IP (using version 12.0 or later), we can perform that last 80% for you. Using Cloud-init with BIG-IP As you can imagine, there’s quite a lot you can do with just that one simple bash script shown above. However, more interestingly, we also installed AWS’s Cloudformation Helper scripts. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-helper-scripts-reference.html to help extend cloud-init and unlock a larger more powerful set of AWS functionality. So when used with Cloudformation, our User Data simply changes to executing the following AWS Cloudformation helper script instead. "UserData": { "Fn::Base64": { "Fn::Join": [ "", [ "#!/bin/bash\n", "/opt/aws/apitools/cfn-init-1.4-0.amzn1/bin/cfn-init -v -s ", { "Ref": "AWS::StackId" }, " -r ", "Bigip1Instance", " --region ", { "Ref": "AWS::Region" }, "\n" ] ] } } This allows us to do things like obtaining variables passed in from Cloudformation environment, grabbing various information from the metadata service, creating or downloading files, running particular sequence of commands, etc. so once BIG-IP has finishing running, our entire application delivery service is up and running. For more information, this page discusses how meta-data is attached to an instance using CloudFormation templates: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-init.html#aws-resource-init-commands. Example BYOL and Utility CloudFormation Templates We’ve posted several examples on github to get you started. https://github.com/f5networks/f5-aws-cloudformation In just a few short clicks, you can have an entire BIG-IP deployment up and running. The two examples belowwill launch an entire reference stack complete with VPCs, Subnets, Routing Tables, sample webserver, etc. andshow the use of cloud-init to bootstrap a BIG-IP. Cloud-init is used to configure interfaces, Self-IPs, database variables, a simple virtual server, and in the case of of the BYOL instance, to license BIG-IP.

Take a look at the “Ref” stanzas. When this file is laid down on the BIG-IP disk itself, those variables will be interpolated and contain the actual contents. The idea here is to try to keep config and execution separate. /tmp/firstrun.utils – These are just some helper functions to help with initial provisioning. We use those to determine when the BIG-IP is ready for this particular configuration (ex. after a licensing or provisioning step). Note that instead of creating the file inline like the config file above, we simply “source” or download the file from a remote location. /tmp/firstrun.sh – This file is created inline as well and where it really all comes together. The first thing we do is load config variables from the firstrun.conf file and load the helper functions from firstrun.utils. We then create separate log file (/tmp/firstrun.log) to capture the output of this particular script. Capturing the output of these various commands just helps with debugging runs. Then we run a function called checkF5Ready (that we loaded from that helper function file) to make sure BIG-IP’s database is up and ready to accept a configuration. The rest may look more familiar and where most of the user customization takes place. We use variables from the config file to configure the BIG-IP using familiar methods like TMSH and iControl REST. Technically, you could lay down an entire config file (like SCF) and load it instead. We use tmsh here for simplicity. The possibilities are endless though. Disclaimer: the specific implementation above will certainly be optimized and evolve but the most important take away is we can now leverage cloud-init and AWS's helper libraries to help bootstrap the BIG-IP into a working configuration from the very first boot! Debugging Cloud-init What if something goes wrong? Where do you look for more information? The first place you might look is in various cloud-init logs in /var/log (cloud-init.log, cfn-init.log, cfn-wire.log): Below is an example for the CFTs below: [admin@ip-10-0-0-205:NO LICENSE:Standalone] log # tail -150 cfn-init.log 2016-01-11 10:47:59,353 [DEBUG] CloudFormation client initialized with endpoint https://cloudformation.us-east-1.amazonaws.com 2016-01-11 10:47:59,353 [DEBUG] Describing resource BigipEc2Instance in stack arn:aws:cloudformation:us-east-1:452013943082:stack/as-testing-byol-bigip/07c962d0-b893-11e5-9174-500c217b4a62 2016-01-11 10:47:59,782 [DEBUG] Not setting a reboot trigger as scheduling support is not available 2016-01-11 10:47:59,790 [INFO] Running configSets: default 2016-01-11 10:47:59,791 [INFO] Running configSet default 2016-01-11 10:47:59,791 [INFO] Running config config 2016-01-11 10:47:59,792 [DEBUG] No packages specified 2016-01-11 10:47:59,792 [DEBUG] No groups specified 2016-01-11 10:47:59,792 [DEBUG] No users specified 2016-01-11 10:47:59,792 [DEBUG] Writing content to /tmp/firstrun.config 2016-01-11 10:47:59,792 [DEBUG] No mode specified for /tmp/firstrun.config 2016-01-11 10:47:59,793 [DEBUG] Writing content to /tmp/firstrun.sh 2016-01-11 10:47:59,793 [DEBUG] Setting mode for /tmp/firstrun.sh to 000755 2016-01-11 10:47:59,793 [DEBUG] Setting owner 0 and group 0 for /tmp/firstrun.sh 2016-01-11 10:47:59,793 [DEBUG] Running command b-configure-BigIP 2016-01-11 10:47:59,793 [DEBUG] No test for command b-configure-BigIP 2016-01-11 10:47:59,840 [INFO] Command b-configure-BigIP succeeded 2016-01-11 10:47:59,841 [DEBUG] Command b-configure-BigIP output: % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 40 0 40 0 0 74211 0 --:--:-- --:--:-- --:--:-- 40000 2016-01-11 10:47:59,841 [DEBUG] No services specified 2016-01-11 10:47:59,844 [INFO] ConfigSets completed 2016-01-11 10:47:59,851 [DEBUG] Not clearing reboot trigger as scheduling support is not available [admin@ip-10-0-0-205:NO LICENSE:Standalone] log # If trying out the example templates above, you can inspect the various files mentioned. Ex. In addition to checking for their general presence: /tmp/firstrun.config= make sure variables were passed as you expected. /tmp/firstrun.utils= Make sure exists and was downloaded /tmp/firstrun.log = See if any obvious errors were outputted. It may also be worth checking AWS Cloudformation Console to make sure you passed the parameters you were expecting. Single-NIC Another one of the important building blocks introduced with 12.0 on AWS and Azure Virtual Editions is the ability to run BIG-IP with just a single network interface. Typically, BIG-IPs were deployed in a multi-interface model, where interfaces were attached to an out-of-band management network and one or more traffic (or "data-plane") networks. But, as we know, cloud architectures scale by requiring simplicity, especially at the network level. To this day, some clouds can only support instances with a single IP on a single NIC. In AWS’s case, although they do support multiple NIC/multiple IP, some of their services like ELB only point to first IP address of the first NIC. So this Single-NIC configuration makes it not only possible but also dramatically easier to deploy in these various architectures. How this works: We can now attach just one interface to the instance and BIG-IP will start up, recognize this, use DHCP to configure the necessary settings on that interface. Underneath the hood, the following DB keys will be set: admin@(ip-10-0-1-65)(cfg-sync Standalone)(Active)(/Common)(tmos)# list sys db provision.1nic one-line sys db provision.1nic { value "enable" } admin@(ip-10-0-1-65)(cfg-sync Standalone)(Active)(/Common)(tmos)# list sys db provision.1nicautoconfig one-line sys db provision.1nicautoconfig { value "enable" } provision.1nic = allows both management and data-plane to use the same interface provision.1nicautoconfig = uses address from DHCP to configure a vlan, Self-IP and default gateway. Ex. network objects automatically configured admin@(ip-10-0-1-65)(cfg-sync Standalone)(Active)(/Common)(tmos)# list net vlan net vlan internal if-index 112 interfaces { 1.0 { } } tag 4094 } admin@(ip-10-0-1-65)(cfg-sync Standalone)(Active)(/Common)(tmos)# list net self net self self_1nic { address 10.0.1.65/24 allow-service { default } traffic-group traffic-group-local-only vlan internal } admin@(ip-10-0-1-65)(cfg-sync Standalone)(Active)(/Common)(tmos)# list net route net route default { gw 10.0.1.1 network default } Note: Traffic Management Shell and the Configuration Utility (GUI) are still available on ports 22 and 443 respectively. If you want to run the management GUI on a higher port (for instance if you don’t have the BIG-IPs behind a Port Address Translation service (like ELB) and want to run an HTTPS virtual on 443), use the following commands: tmsh modify sys httpd ssl-port 8443 tmsh modify net self-allow defaults add { tcp:8443 } tmsh modify net self-allow defaults delete { tcp:443 } WARNING: Now that management and dataplane run on the same interface, make sure to modify your Security Groups to restrict access to SSH and whatever port you use for the Mgmt GUI port to trusted networks. UPDATE: On Single-Nic, Device Service Clustering currently only supports Configuration Syncing (Network Failover is restricted for now due to BZ-606032). In general, the single-NIC model lends itself better to single-tenant or per-app deployments, where you need the advanced services from BIG-IP like content routing policies, iRules scripting, WAF, etc. but don’t necessarily care for maintaining a management subnet in the deployment and are just optimizing or securing a single application. By single tenant we also mean single management domain as you're typically running everything through a single wildcard virtual (ex. 0.0.0.0/0, 0.0.0.0/80, 0.0.0.0/443, etc.) vs. giving each tenant its own Virtual Server (usually with its own IP and configuration) to manage. However, you can still technically run multiple applications behind this virtual with a policy or iRule, where you make traffic steering decisions based on L4-L7 content (SNI, hostname headers, URIs, etc.). In addition, if the BIG-IPs are sitting behind a Port Address Translation service, it also possible to stack virtual services on ports instead. Ex. 0.0.0.0:444 = Virtual Service 1 0.0.0.0:445 = Virtual Service 2 0.0.0.0:446 = Virtual Service 3 We’ll let you get creative here…. BIG-IP Auto Scale Finally, the last component of Auto Scaling BIG-IPs involves building scaling policies via Cloudwatch Alarms. In addition to the built-in EC2 metrics in CloudWatch, BIG-IP can report its own set of metrics, shown below: Figure 3: Cloudwatch metrics to scale BIG-IPs based on traffic load. This can be configured with the following TMSH commands on any version 12.0 or later build: tmsh modify sys autoscale-group autoscale-group-id ${BIGIP_ASG_NAME} tmsh load sys config merge file /usr/share/aws/metrics/aws-cloudwatch-icall-metrics-config These commands tell BIG-IP to push the above metrics to a custom “Namespace” on which we can roll up data via standard aggregation functions (min, max, average, sum). This namespace (based on Auto Scale group name) will appear as a row under in the “Custom metrics” dropdown on the left side-bar in CloudWatch (left side of Figure 1). Once these BIG-IP or EC2 metrics have been populated, CloudWatch alarms can be built, and these alarms are available for use in Auto Scaling policies for the BIG-IP Auto Scale group. (Amazon provides some nice instructions here). Auto Scaling Pool Members and Service Discovery If you are scaling your ADC tier, you are likely also going to be scaling your application as well. There are two options for discovering pool members in your application's auto scale group. 1) FQDN Nodes For example, in a typicalsandwichdeployment, your application members might also be sitting behind an internal ELB so you would simply point your FQDN node at the ELB's DNS. For more information, please see: https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-12-1-0/25.html?sr=56133323 2) BIG-IP's AWS Auto Scale Pool Member Discovery feature (introduced v12.0) This feature polls the Auto Scale Group via API calls and populates the pool based on its membership. For more information, please see: https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-ve-autoscaling-amazon-ec2-12-1-0/2.html Putting it all together The high-level steps for Auto Scaling BIG-IP include the following: Optionally* creating an ElasticLoadBalancer group which will direct traffic to BIG-IPs in your Auto Scale group once they become operational. Otherwise, will need Global Server Load Balancing (GSLB). Creating a launch configuration in EC2 (referencing either custom image id and/or using Cloud-init scripts as described above) Creating an Auto Scale group using this launch configuration Creating CloudWatch alarms using the EC2 or custom metrics reported by BIG-IP. Creating scaling policies for your BIG-IP Auto Scale group using the alarms above. You will want to create both scale up and scale down policies. Here are some things to keep in mind when Auto Scaling BIG-IP ● BIG-IP must run in a single-interface configuration with a wildcard listener (as we talked about earlier). This is required because we don't know what IP address the BIG-IP will get. ● Auto Scale Groups themselves consist of utility instances of BIG-IP ● The scale up time for BIG-IP is about 12-20 minutes depending on what is configured or provisioned. While this may seem like a long-time, creating the right scaling policies (polling intervals, thresholds, unit of scale) make this a non-issue. ● This deployment model lends itself toward the themes of stateless, horizontal scalability and immutability embraced by the cloud. Currently, the config on each device is updated once and only once at device startup. The only way to change the config will be through the creation of a new image or modification to the launch configuration. Stay tuned for a clustered deployment which is managed in a more traditional operational approach. If interesting in exploring Auto Scale further, we have put together some examples of scaling the BIG-IP tier here: https://github.com/f5devcentral/f5-aws-autoscale * Above github repository also provides some examples of incorporating BYOL instances in the deployment to help leverage BYOL instances for your static load and using Auto Scale instances for your dynamic load. See the READMEs for more information. CloudFormation templates with Auto Scaled BIG-IP and Application Need some ideas on how you might leverage these solutions? Now that you can completely deploy a solution with a single template, how about building service catalog items for your business units that deploy different BIG-IP services (LB, WAF) or a managed service build on top of AWS that can be easily deployed each time you on-board a new customer?
Why the BIG-IP VE OVA does not work on Virtualbox
I've seen this question asked on this forum as well as on several other forums across the internet, so I wanted to put together this article to answer folks' questions and to settle the discussion. I'll also discuss options that you have for working around it. The VE images I am working with will be from downloads.f5.com. Perspective Sometimes things like this get lost in the noise that PM should be channeling back to the maintainers of these products. Other times, PM does exactly what's needed to be done, but then it gets filed as "meh, not that important" and it gets checked on every 6 months or so to see if there has been any movement on it. In this case, I just don't think enough people were making a fuss about it to attract any development effort. If something is listed as "not supported", that's usually why its not supported. There are many times though that a person in-house will need to scratch an itch. This is one of those cases. I do not work on the team that builds the images that are available for download, but I have a great working relationship with them, so they gave me the access needed to squirrel around and find the answer. Build process insight The build process itself is encapsulated in a biiiiiig shell script. It throws off a number of different VE images. To understand why the OVA fails, you need to understand what the build process does a little something about virtualbox The process to build the VE's starts with QEMU. For the, what I will call "standard" VE's ( ALL-ide.ova , ALL-scsi.ova , ALL.qcow2 , etc),the QEMU command attaches 2 disk drives during build; 1 for the system, and one for a data store. For the VE's that are known as 1SLOT VE's, that second disk (the data store one) is never created. 1SLOTS are intended only to be used for LTM. As such, adequate disk space is not allocated for "everything else". You get ~7G of space and that's it. To create those drives and attach them as needed by qemu, we simply append more and more " -drive=blah blah blah " parameters. Ok, so that collection of QEMU commands eventually gets us a RAW image that we can transform into a number of different formats. One of those formats is OVA, which is created by use of the ovftool command. The output of that command is an OVA file. For those unfamiliar with it, an OVA file is just a tarball that includes an OVF file, a number of disks, and some other "stuff" that you might want to include (certificates, eula files, yada yada yada). An OVA file is picky though as to the order that files are added to it. The OVF file must come first. Virtualbox Virtualbox will happily support more than one disk on a single controller. It will not, however, support more than one controller. On the surface, you would think this is not a problem. After all, when you "Import Appliance", it will happily list both of the controllers there. In fact, the OVF file can even include multiple controllers in it, as we'll see below. The Problem So the problem stems from one of these tools, qemu or ovftool , attaching the second disk to the second controller. If the disk were attached to the first controller, then everything would be fine. It's the lack of multiple controller support in Virtualbox that gums up the machine. VMWare allows multiple controllers, so this would explain why nobody in CM saw this problem when they created the OVA. So can you workaround this problem in any way so that you get a working OVA on Virtualbox? Answer: Yes. It's not even a difficult workaround, but I wonder if it changes anything in the functionality of the OVA as imported into Virtualbox? I suspect not, but if you're willing to hack on the VE, then I assume you're not all that concerned with the VE working 100% as designed either. I just needed it to give me a REST and SOAP API that I could throw scripts at to test stuff. I'm OK with hacking on the VE. Workarounds Since I'm not privy to the CM team's work pipeline, I can't even begin to guess at when (or if) this will be fixed. I suspect that "since it works in our supported platforms" it won't be fixed any time soon. Who knows. In the meantime, here is a way to fix the problem if you are unable to resort to using the 1SLOT OVA. I am going to use the IDE version in this example, but similar steps will apply to the SCSI image. Starting with the VE image, we'll use tar to extract its contents to view them. SEA-ML-RUPP1:tim trupp$ tar xvf BIGIP-12.0.0.0.0.606.ALL-ide.ova x BIGIP-12.0.0.0.0.606-ide.ovf x BIGIP-12.0.0.0.0.606-ide.mf x BIGIP-12.0.0.0.0.606-ide.cert x BIGIP-12.0.0.0.0.606-disk1.vmdk x BIGIP-12.0.0.0.0.606-disk2.vmdk SEA-ML-RUPP1:tim trupp$ Now, let's take a moment to just copy those file names and put them in a temporary file. The reason we do this is because we will need to recreate the OVA later, but because it has a specific file list we need to specify that list when we recreate the file. I just stick the file list in a file called "files.txt" BIGIP-12.0.0.0.0.606-ide.ovf BIGIP-12.0.0.0.0.606-ide.mf BIGIP-12.0.0.0.0.606-ide.cert BIGIP-12.0.0.0.0.606-disk1.vmdk BIGIP-12.0.0.0.0.606-disk2.vmdk From here on out, the remaining work will be done in the OVF file, so open that in your favorite editor. With it open, search around the bottom of the file for this block. <Item> <rasd:AddressOnParent>0</rasd:AddressOnParent> <rasd:ElementName>disk2</rasd:ElementName> <rasd:HostResource>ovf:/disk/vmdisk2</rasd:HostResource> <rasd:InstanceID>6</rasd:InstanceID> <rasd:Parent>3</rasd:Parent> <rasd:ResourceType>17</rasd:ResourceType> </Item> There are two values we will want to change here. They are <rasd:AddressOnParent>0</rasd:AddressOnParent> <rasd:Parent>3</rasd:Parent> You want to change those values to be the following <rasd:AddressOnParent>1</rasd:AddressOnParent> <rasd:Parent>4</rasd:Parent> Then, save the file. What we have accomplished with this change is that we have removed the disk from the second controller, and attached it as a second disk on the first controller. With all disks being on one controller, the OVA will now boot fine in Virtualbox. Let's repack up the OVA. tar-cvfBIGIP-12.0.0.0.0.606.ALL-ide-FIXED.ova -T files.txt This should deliver output that resembles the following SEA-ML-RUPP1:tim trupp$ tar -cvf BIGIP-12.0.0.0.0.606.ALL-ide-FIXED.ova -T files.txt a BIGIP-12.0.0.0.0.606-ide.ovf a BIGIP-12.0.0.0.0.606-ide.mf a BIGIP-12.0.0.0.0.606-ide.cert a BIGIP-12.0.0.0.0.606-disk1.vmdk a BIGIP-12.0.0.0.0.606-disk2.vmdk SEA-ML-RUPP1:tim trupp$ And that should be all you need to do. With the fixed OVA made, open it up in Virtualbox and have at it. One last thing. Remember I mentioned that multiple controllers could be specified as long as no disks were attached to the second controller? Take a look at the OVF file again and you will see this block <Item> <rasd:Address>1</rasd:Address> <rasd:Description>IDE Controller</rasd:Description> <rasd:ElementName>ideController1</rasd:ElementName> <rasd:InstanceID>3</rasd:InstanceID> <rasd:ResourceType>5</rasd:ResourceType> </Item> <Item> <rasd:Address>0</rasd:Address> <rasd:Description>IDE Controller</rasd:Description> <rasd:ElementName>ideController0</rasd:ElementName> <rasd:InstanceID>4</rasd:InstanceID> <rasd:ResourceType>5</rasd:ResourceType> </Item> Proof that more than one controller can exist, but when you boot the fixed OVA, it still works right? Weird. Anyways, I hope this was useful and answers any outstanding questions you may have had about why the OVA doesn't work on Virtualbox.
What am I doing wrong with this network configuration for KVM (F5 virtual edition)
Hello, I have been trying to setup an F5 lab using KVM on debian. I currently have the following network configuration (/etc/network/interfaces - see output pasted at end of post) although whenever I go to create the VM in KVM, only one tap is associated with the bridge (trying to use the taps for management, external, and internal interfaces on the F5 VM). (see screenshot at end of post) Would anyone have any suggestions for configuring networking properly for this setup? I'm open to anything at this point in time. Thanks for your help. source /etc/network/interfaces.d/* auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet dhcp iface eth0 inet6 auto auto br0 iface br0 inet dhcp pre-up ip tuntap add dev tap0 mode tap user root pre-up ip tuntap add dev tap1 mode tap user root pre-up ip tuntap add dev tap2 mode tap user root pre-up ip link set tap0 up pre-up ip link set tap1 up pre-up ip link set tap2 up bridge_ports all tap0 tap1 tap2 bridge_stp off bridge_maxwait 0 bridge_fd 0 post-down ip link set tap0 down post-down ip link set tap1 down post-down ip link set tap2 down post-down ip tuntap del dev tap0 mode tap post-down ip tuntap del dev tap1 mode tap post-down ip tuntap del dev tap2 mode tapCreated new vcmp guest with initial image 11.5.1, but sys software shows version 11.4.1
Hi, I just created a new vcmp guest using the initial image BIGIP-11.5.1.0.0.110.iso, after provisioning and deployment, from the Hypervisor dashboard I see that the initial image and hotfix are correctly applied. However, from the CLI tmsh, the output is different. How is this possible? What am I missing? [root@lb2-a-vm9:/S2-green-P:Active:Standalone] log tmsh root@(lb2-a-vm9)(cfg-sync Standalone)(/S2-green-P:Active)(/Common)(tmos) show sys software ------------------------------------------------------- Sys::Software Status Volume Slot Product Version Build Active Status ------------------------------------------------------- HD1.1 2 BIG-IP 11.4.1 647.0 yes complete HD1.2 2 none none none no complete HD1.3 2 none none none no complete Below is a snampshot of the Hypervisor vcmp guest showing the image:
