WAN Optimization is not Application Acceleration
Increasingly WAN optimization solutions are adopting the application acceleration moniker, implying a focus that just does not exist. WAN optimization solutions are designed to improve the performance of the network, not applications, and while the former does beget improvements of the latter, true application acceleration solutions offer greater opportunity for improving efficiency and end-user experience as well as aiding in consolidation efforts that result in a reduction in operating and capital expenditure costs. WAN Optimization solutions are, as their title implies, focused on the WAN; on the network. It is their task to improve the utilization of bandwidth, arrest the effects of network congestion, and apply quality of service policies to speed delivery of critical application data by respecting application prioritization. WAN Optimization solutions achieve these goals primarily through the use of data de-duplication techniques. These techniques require a pair of devices as the technology is most often based on a replacement algorithm that seeks out common blocks of data and replaces them with a smaller representative tag or indicator that is interpreted by the paired device such that it can reinsert the common block of data before passing it on to the receiver. The base techniques used by WAN optimization are thus highly effective in scenarios in which large files are transferred back and forth over a connection by one or many people, as large chunks of data are often repeated and the de-duplication process significantly reduces the amount of data traversing the WAN and thus improves performance. Most WAN optimization solutions specifically implement “application” level acceleration for protocols aimed at the transfer of files such as CIFS and SAMBA. But WAN optimization solutions do very little to aid in the improvement of application performance when the data being exchanged is highly volatile and already transferred in small chunks. Web applications today are highly dynamic and personalized, making it less likely that a WAN optimization solution will find chunks of duplicated data large enough to make the overhead of the replacement process beneficial to application performance. In fact, the process of examining small chunks of data for potential duplicated chunks can introduce additional latency that actual degrades performance, much in the same way compression of small chunks of data can be detrimental to application performance. Too, WAN optimization solutions require deployment in pairs which results in what little benefits these solutions offer for web applications being enjoyed only by end-users in a location served by a “remote” device. Customers, partners, and roaming employees will not see improvements in performance because they are not served by a “remote” device. Application acceleration solutions, however, are not constrained by such limitations. Application acceleration solutions act at the higher layers of the stack, from TCP to HTTP, and attempt to improve performance through the optimization of protocols and the applications themselves. The optimizations of TCP, for example, reduce the overhead associated with TCP session management on servers and improve the capacity and performance of the actual application which in turn results in improved response times. The understanding of HTTP and both the browser and server allows application acceleration solutions to employ techniques that leverage cached data and industry standard compression to reduce the amount of data transferred without requiring a “remote” device. Application acceleration solutions are generally asymmetric, with some few also offering a symmetric mode. The former ensures that regardless of the location of the user, partner, or employee that some form of acceleration will provide a better end-user experience while the latter employs more traditional WAN optimization-like functionality to increase the improvements for clients served by a “remote” device. Regardless of the mode, application acceleration solutions improve the efficiency of servers and applications which results in higher capacities and can aid in consolidation efforts (fewer servers are required to serve the same user base with better performance) or simply lengthens the time available before additional investment in servers – and the associated licensing and management costs – must be made. Both WAN optimization and application acceleration aim to improve application performance, but they are not the same solutions nor do they even focus on the same types of applications. It is important to understand the type of application you want to accelerate before choosing a solution. If you are primarily concerned with office productivity applications and the exchange of large files (including backups, virtual images, etc…) between offices, then certainly WAN optimization solutions will provide greater benefits than application acceleration. If you’re concerned primarily about web application performance then application acceleration solutions will offer the greatest boost in performance and efficiency gains. But do not confuse WAN optimization with application acceleration. There is a reason WAN optimization-focused providers have recently begun to partner with application acceleration and application delivery providers – because there is a marked difference between the two types of solutions and a single offering that combines them both is not (yet) available.Lightboard Lessons: Service Consolidation on BIG-IP
The Consolidation of point devices and services in your datacenter or cloud can help with cost, complexity, efficiency, management, provisioning and troubleshooting your infrastructure and systems. In this Lightboard Lesson, I light up many of the services you can consolidate on BIG-IP. psHardware Acceleration Critical Component for Cost-Conscious Data Centers
Better performance, reduced costs and data center footprint are not niche-market interests. The fast-paced world of finance is taking a hard look at the benefits of hardware acceleration for performance and finding additional benefits such as a reduction in rack-space via consolidation of server hardware. Rich Miller over at Data Center Knowledge writes: Hardware acceleration addresses computationally-intensive software processes that task the CPU, incorporating special-purpose hardware such as a graphics processing unit (GPUs) or field programmable gate array (FPGA) to shift parallel software functions to the hardware level. … “The value proposition is not just to sustain speed at peak but also a reduction in rack space at the data center,” Adam Honore, senior analyst at Aite Group, told WS&T. Depending on the specific application, Honore said a hardware appliance can reduce the amount of rack space by 10-to-1 or 20-to-1 in certain market data and some options events. Thus, a trend that bears watching for data center providers. But confining the benefits associated with hardware acceleration to just data center providers or financial industries is short-sighted, because similar benefits can be achieved by any data center in any industry looking for cost-cutting technologies. And today, that’s just about … everyone. USING SSL? YOU CAN BENEFIT FROM HARDWARE ACCELERATION Now maybe I’m just too into application delivery and hardware and all its associated benefits, but the idea that hardware acceleration and offloading of certain computationally expensive tasks like encryption, decryption, TCP session management, etc… seems pretty straightforward, and not exclusive to financial markets. Any organization using SSL, for example, can see benefits in both performance and a reduction in costs through consolidation by offloading the responsibility for SSL to an external device that employs some sort of hardware-based acceleration of the specific computationally expensive functions. This is the same concept used by routers and switches, and why they employ FPGAs and ASICs to perform network processing: they’re faster and capable of much greater speeds than their software predecessors. Unlike routers and switches, however, solutions capable of hardware-based acceleration provide the added benefit of reducing the utilization on hardware servers while improving the speed at which such computations can be executed. Reducing the utilization on servers means increased capacity on each server, which results in either the ability to eliminate a number of servers or the need to invest in even more servers. Both strategies result in a reduction in costs associated with the offloading of the expensive functionality. Add hardware-based acceleration of SSL operations with hardware-based acceleration for compression of data and you can offload yet another computationally expensive piece of functionality to an external device, which again saves resources on the server and increases its capacity as well as the overall response time for transfers requiring compression. Now put that functionality onto your load-balancer, a fairly logical place in your architecture to apply such functionality both ingress and egress, and what you’ve got is an application delivery controller. Add to the hardware-based acceleration of SSL and compression an optimized TCP stack that reuses TCP connections and you not only increase performance but decrease utilization on the server yet again because it’s handling fewer connections and not going through the tedium of opening and closing connections at a fairly regular rate. NOT JUST FOR ADMINS and NETWORK ARCHITECTS Developers and architects, too, can apply the benefits of hardware accelerated services to their applications and frameworks. Cookie encryption, for example, is a fairly standard method of protecting web applications against cookie-based attacks such as cookie tampering and poisoning. Encryption of cookies mitigates that risk by ensuring that cookies stored on clients are not human-readable. But encryption and decryption of cookies can be expensive and often comes at the cost of performance of the application and, if not implemented as part of the original design, can cost in terms of the time and money necessary to add the feature to the application. Leveraging the network-side scripting capabilities of application delivery controllers removes the need to rewrite the application by allowing cookies to be encrypted and decrypted on the application delivery controller. By moving the task of (de|en)cryption to the application delivery controller, the expensive computations required by the process are accelerated in hardware and will not negatively impact the performance of the application. If the functionality is moved from within the application to an application delivery controller, the resulting shift in computational burden can reduce utilization on the server – particularly in heavily used applications or those with a larger set of cookies – which, like other reductions in server utilization, can lead to the ability to consolidate or retire servers in the data center. HARDWARE ACCELERATION REDUCES COSTS, INCREASES EFFICIENCY By the time you get finished, the case for consolidating servers seems fairly obvious: you’ve offloaded so much intense functionality that you can cut the number of servers you need by a considerable amount, and either retire them (decreasing power, cooling, heating, and rack space in the process) or re-provision them for use on other projects (decreasing investment and acquisition costs for the other project and maintaining current operating expenses rather than increasing them). Basically, if you need load balancing you’ll benefit both technically and financially from investing in an application delivery controller rather than a traditional simple load balancer. And if you don’t need load balancing, you can still benefit simply by employing the offloading capabilities inherent in such platforms endowed with hardware-assisted acceleration technologies. The increased efficiency of servers resulting from the use of hardware-assisted offload of computationally expensive operations can be applied to any data center and any application in any industry.CloudFucius Shares: Cloud Research and Stats

At Interop this week, security experts have begun sounding the drum regarding the security risks of virtualization and reminding us that virtual server sprawl magnifies that risk because, well, there are more virtual servers to manage at risk. Virtual sprawl isn't defined by numbers; it's defined as the proliferation of virtual machines without adequate IT control, [David] Lynch said. That's good, because the numbers as often cited just don't add up. A NetworkWorld article in December 2007 cited two different sets of numbers from Forrester Research on the implementation of virtualization in surveyed organizations. First we are told that: IT departments already using virtualization have virtualized 24% of servers, and that number is expected to grow to 45% by 2009. And later in the article we are told: The latest report finds that 37% of IT departments have virtualized servers already, and another 13% plan to do so by July 2008. An additional 15% think they will virtualize x86 servers by 2009. It's not clear where the first data point is coming from, but it appears to come from a Forrester Research survey cited in the first paragraph while the latter data set appears to come from the same recent study. The Big Hairy Question is: how many virtual servers does that mean? This sounds a lot like the great BPM (Business Process Management) scare of 2005 when it was predicted that business users would be creating SOA-based composite applications willy nilly using BPM tools because it required no development skills, just a really good mouse finger with which you could drag and drop web services to create your own customized application. Didn't happen. Or if it did, it happened in development and test and local environments and never made it to the all important production environment, where IT generally maintains strict control. Every time you hear virtual server sprawl mentioned it goes something like this: "When your users figure out how easy it is..." "Users", whether IT or business, are not launching virtual servers in production in the data center. If they are, then an organization has bigger concerns on their hands than the issue of sprawl. Are they launching virtual servers on their desktop? Might be. On a test or development machine? Probably. In production? Not likely. And that's where management and capacity issues matter; that's where the bottom line is potentially impacted from a technological black plague like virtual server sprawl; that's where the biggest security and management risks associated with virtualization are going to show themselves. None of the research cited ever discusses the number of virtual servers running, just the number of organizations in which virtualization has been implemented. That could mean 1 or 10 or 100 virtual servers. We just don't know because no one has real numbers to back it up; nothing but limited anecdotal evidence has been presented to indicate that there is a problem with virtual server sprawl. I see problems with virtualization. I see the potential for virtualizing solutions that shouldn't be virtualized for myriad reasons. I see the potential problems inherent in virtualizing everything from the desktop to the data center. But I don't see virtual server sprawl as the Big Hairy Monster hiding under the virtual bed. So as much as I'd like to jump on the virtual sprawl bandwagon and make scary faces in your general direction about the dangers that lie within the virtual world - because many of them are very real and you do need to be aware of them - there just doesn't seem to be any real data to back up the claim that virtual sprawl is - or will become - a problem.Simplify VMware View Deployments
Virtual Desktop Infrastructure (VDI) or the ability to deliver desktops as a managed service is an attractive and cost effective solution to mange a corporate desktop environment. The success of virtual desktop deployments hinges on the user experience, availability and performance, security and IT's ability to reduce desktop operating expenses. VDI deployments virtualizes user desktops by delivering them to distinctive end point devices over the network from a central location. Since the user's primary work tool is now located in a data center rather than their own local machine, VDI can put a strain on network resources while the user experience can be less than desired. This is due to the large amounts of data required to deliver a graphical user interface (GUI) based virtual desktop. For users who want to access their desktops and applications from anywhere in the world, network latency can be especially noticeable when the virtual desktop is delivered over a WAN. Organizations might have to provision more bandwidth to account for the additional network traffic which in turn, reduces any cost savings realized with VDI. In addition, VMware has introduced the PCoIP (PC over IP) communications display protocol which makes more efficient use of the network by encapsulating video display packets in UDP instead of TCP. Many remote access devices are incapable of correctly handling this distinctive protocol and this can deteriorate the user experience. Keeping mobile users connected to their own unique, individual environments can also pose a challenge. When a user is moving from one network to another, their session could be dropped, requiring them to re-connect, re-authenticate, and navigate to where they were prior to the interruption. Session-persistence can maintain the stateful desktop information helping users reconnect quickly without the need to re-authenticate. Secure access and access control are always concerns when deploying any system and virtual desktops are no different. Users are still accessing sensitive corporate information so enforcing strong authentication, security policies, and ensuring that the client is compliant all still apply to VDI deployments. Lastly, IT must make sure that the virtual systems themselves are available and can scale when needed to realize all the benefits from both a virtual server and virtual desktop deployment. The inclusion of BIG-IP APM's fine grained access control to BIG-IP LTM VE offers a very powerful enhancement to a VMware View deployment. BIG-IP APM for LTM VE is an exceptional way to optimize, secure, and deliver a VMware View virtual desktop infrastructure. This is a 100% virtual remote access solution for VMware View 4.5 VDI solutions. In addition, the BIG-IP APM for LTM VE system will run as a virtual machine in a VMware hypervisor environment so you can easily add it to your existing infrastructure. As the number of users on virtual desktops grows, customers can easily transition from the BIG-IP virtual edition to a BIG-IP physical appliance. The BIG-IP provides important load balancing, health monitoring and SSL Offload for VMware View deployments for greater system availability and scalability. Network and protocol optimizations help organizations mange bandwidth efficiently and in some cases, reduces the bandwidth requirements while maintaining and improving the user experience. BIG-IP APM for LTM VE also opens the possibility of making virtual server load balancing decisions based on user’s identity, ensuring the user is connected to the optimal virtual instance based their needs. F5 also overcomes the PCoIP challenge with our Datagram Transport Layer Security (DTLS) feature. This transport protocol is uniquely capable of providing all the desired security for transporting PCoIP communications but without the degradation in performance. In addition, F5 supports View’s automatic fallback to TCP if a high performance UDP tunnel cannot be established. Users no longer have to RDP to their virtual desktops but can now connect directly with PCoIP or organizations can plan a phased migration to PCoIP. The BIG-IP APM for LTM VE comes with powerful security controls to keep the entire environment secure. Pre-login host checks will inspect the requesting client and determine if it meets certain access criteria like OS patch level, Anti-virus/Firewall state or if a certificate is present. BIG-IP APM for LTM VE offers a wide range of authentication mechanisms, including two-factor, to protect corporate resources from unauthorized access. BIG-IP APM enables authentication pass-through for convenient single sign on and once a session is established, all traffic, including PCoIP, is encrypted to protect the data and session-persistence helps users reconnect quickly without having to re-authenticate. BIG-IP APM for LTM VE simplifies deployment of authentication and session management for VMware View enterprise virtual desktop management. ps Resources F5 Accelerates VMware View Deployments with BIG-IP Access Policy Manager on a Virtual Platform BIG-IP Local Traffic Manager Virtual Edition BIG-IP Access Policy Manager Application Delivery and Load Balancing for VMware View Desktop Infrastructure Deploying F5 Application Ready Solutions with VMware View 4.5 Optimizing VMware View VDI Deployments Global Distributed Service in the Cloud with F5 and VMware WILS: The Importance of DTLS to Successful VDI F5 Friday: The Dynamic VDI Security Game F5 Friday: Secure, Scalable and Fast VMware View Deployment Technorati Tags: F5, BIG-IP, VMWare, Optimization, Pete Silva, F5, vmview,virtualization,mobile applications,access control,security,context-aware,strategic point of controlWho In The World Are You?
Steven Wright has said, 'It's a small world, but I wouldn't want to paint it.' The world is getting smaller with today's 24/7 global marketplace. Businesses have offices and employees around the world to serve the needs of the organization's global customers. Those users, whether they are in a branch office, home office or mobile need access to critical information. Data like corporate information, customer information, sales information, financial information, product information and any other sources of business material is important to be able to make smart enterprise decisions. Without access to this data, poor decisions are made and the business can suffer. The recent breaches, especially the intrusions tied to the RSA compromise, has put identity and access management in the spotlight. Once upon a time, users had to be in the office connected to the network to access corporate applications. IT organizations probably knew the user was since they were sitting at a desk; organizations knew the type of device since it was issued by IT and the business applications were delivered quickly and securely since it was from an internal local area network. Then, users needed access to that same information while they were away from the office and solutions like VPNs and Remote Access quickly gained acceptance. As adoption grew, so did requests for access above and beyond the normal employee. Soon partners, contractors, vendors and other 3rd party ecosystems were given access to corporate resources. Employees and partners from around the globe were connecting from a barrage of networks, carriers and devices. This can be very risky since IT might not know the identity of those users. Anonymous networks allow users to gain access to systems via a User ID and password but they cannot decipher exactly who the user actually is; an employee, guest, contractor, partner and the like. Anonymous networks do have visibility at the IP or MAC address level but that information does not equate to a user's identity. Since these networks are unable to attribute IP to identity, the risk is that information may be available to users who are not authorized to see it. There is also no reporting as to what was accessed or where a specific user has navigated within a system. Unauthorized access to systems is a huge concern for companies, not only pertaining to the disclosure and loss of confidential company data but the potential risks to regulatory compliance and public criticism. It is important that only authenticated users gain admission and that they only access the resources they are authorized to see. Controlling and managing access to system resources must be based on identity. A user's identity, or their expressed or digitally represented identity can include identifiers like: what you say, what you know, where you are, what you share, who you know, your preferences, your choices, your reputation, your profession or any other combination that is unique to the user. Access can mean different things - access to an intranet web application to search for materials, access to MS Exchange for email, access to virtualized Citrix, VMware or Remote Desktop deployments, access to a particular network segment for files and full domain network access as if the user is sitting in the office. The resources themselves can be in multiple locations, corporate headquarters, the data center, at a branch office, in the cloud or a mix of them all. When users are all over the world, globally distributed access across several data centers can help solve access and availability requirements. Organizations also need their application and access security solution in the strategic point of control, a centralized location at the intersection between the users and their resources to make those intelligent, contextual, identity based decisions on how to handle access requests. Residing in this important strategic point of control within the network, the BIG-IP Access Policy Manager (APM) for BIG-IP Local Traffic Manager (LTM) along with BIG-IP Edge Gateway (EGW) provide the security, scalability and optimization that's required for unified global access to corporate resources for all types of deployment environments. The ability to converge and consolidate remote users, LAN access and wireless junctions on a single management interface and provide easy-to-manage access policies saves money and frees up valuable IT resources. F5's access solutions secures your infrastructure, creating a place within the network to provide security, scalability, optimization, flexibility, context, resource control, policy management, reporting and availability for all applications. ps Resources: The IP Address – Identity Disconnect Lost Your Balance?
