Automatic Certificate Management with ACMEv2 in F5 BIG-IP
One of the most anticipated features of F5 BIG-IP is integration with ACMEv2. With the General Availability of BIG-IP 21.1.0 on May/26, this feature came into being. In this tutorial, we are going to configure it, using Let's Encrypt as the CA. The domain for which we are generating/renewing certificates is carlosf5lab.lat. The official docs for this feature are located in SSL Certificate Management | BIG-IP Documentation. Pre-requisite 1: DNS Resolver that can reach the internet (at least the CA endpoints). In this case, we are using the native DNS Resolver that comes with BIG-IP. Pre-requisite 2: The internal proxy that will make the connection with the CA. Pre-requisite 3: a self signed SSL certificate that the ACMEv2 protocol uses as the identifier for a device account. You don't have to fill the Subject Alternative Name. For the Common Name, an e-mail contact is advised. Now, we are going to create the ACME Provider object. Give it a name, and select the internal proxy previously created. For the CA Certificate to enable the secure connection with the Directory URL, you can use the default ca-bundle.crt. The Directory URL is the endpoint for the ACMEv2 protocol. In Let's Encrypt case, it is https://acme-v02.api.letsencrypt.org/directory For the Account Key, choose the previously created self-signed certificate. For the trickier part of all, the field "Contacts" is mandatory, and it must be an URL. That’s why you must use the format mailto:email_address. Check the Terms and Conditions, and the Create Account boxes. After a while, the Account Status must read as "Valid". To prove you own the domain whose certificate Let's Encrypt is going to create/renew, it must be pointing to an IP (A Record) where you must have your Virtual Server listening on Port 80 configured to respond to the ACMEv2 Challenge. (In this specific lab, the domain carlosf5lab.lat points to a Public IP mapped to an internal IP). Now you can order your first certificate via ACMEv2 on BIG-IP: After a while, the Key tab should read something like: Which means your certificate was generated: To track the ACME Provider, you can check its statistics: That's it, my friend!

The guidelines presented in this walkthrough are informed by extensive field experience, incorporating insights from customers, F5 Solutions Engineers, Architects, and Professional Services teams. Having supported numerous deployments across diverse environments, this cumulative knowledge provides a practical and reliable starting point for publishing applications. This guide aims to help navigate the Distributed Cloud platform, offering a balanced approach to application delivery and security. The below figure represents the HTTP-LB configuration options alongside the typical flow of traffic from downstream client to upstream origin or application endpoint. Prerequisites: Article on how Distributed Cloud advertises and picks up traffic (Listener Logic) can be found here: F5 Distributed Cloud - Listener Logic Domains and Certificates: This is where you define what the load balancer listens on and how it presents itself to clients. For an initial deployment with a publicly accessible application, the following settings cover most use cases. We recommend a single HTTP-LB per application for visibility, telemetry, day 2 operations, and blast radius. Any more consolidation may cause friction going forward. Recommended Settings: Domain Name:Your application FQDN (e.g., app.example.com) Load Balancer Type: Certificate: Use F5 XC Auto-Cert when possible. If your domain is delegated to XC DNS, certificate management is fully automated. For non-delegated domains, F5 XC provides a cname challenge record value that you can add to your DNS provider to satisfy the Lets Encrypt ACME challenge, then add the provided Host Name.ves.io CNAME record pointing to XC to complete the certificate setup HTTP to HTTPS Redirect:Enable HSTS Header:Enable Listener Port: 443 Client-Side TLS: High security profile Protocol: HTTP/1.1 and HTTP/2 Origins and Health Checking: Origin Pools: A note on structure and origin access: Use Routes (covered in the next section) as the primary mechanism for attaching Origin Pools to your HTTP LB. The default Origin Pool field on the HTTP LB itself is best reserved as a potential fallback option depending on origin and route design (Engage your F5 SE if you need to discuss further). This approach gives you path-aware routing controls and per-route retry and timeout tuning. Also at the origin premise you should limit access to F5 Distributed Cloud RE’s only. You have a few options to achieve this. Limit via a security group or IP Access List to RE IP ranges, mTLS, insert a response header from the HTTP-LB that the origin server is expecting, or a combination of the 3. Recommended Settings for Publicly Available Endpoints: Origin Server Type: Public IP-based. Provide the IPv4 address directly. Where possible, target origins by IP with Host Header. If using public DNS-based origin endpoint targeting, be aware that XC does not honor standard DNS TTL and overrides the value! Origin Server Port: 443 Connection Pool Reuse: Enable Health Check Port: Endpoint port (same as origin port unless otherwise directed) Load Balancing Algorithm: Load Balancer Override (Load Balancer algorithm set at HTTP-LB) Endpoint Selection: Local Endpoints Preferred (Distributed Cloud Construct to leverage local endpoints over remote endpoints goal is to Egress the same RE as Ingress) TLS to Origin: Enable TLS SNI: Host Header TLS Security Level: High Origin Server Verification: Use Default Root CA Certificate mTLS: Disable unless required Other Origin Pool Options: Exception Handling: Setup for specific application/origin server requirements (configurable options available for application specific error-handling requirements) Origin Server Subsets: Disable unless you have a specific canary or subset routing requirement HTTP Protocol Configuration: Automatic (adjust to a specific version if your origin requires it) Proxy Protocol: Disable LB Source IP Persistence: Disable Health Checks: The default health check thresholds are tuned conservatively. In practice, this means a failed origin stays in rotation longer than it should, and a recovered origin comes back into rotation slowly. Adjust the thresholds to react more aggressively to recovery while still being tolerant of transient failures. Recommended Health Check Settings: Setting Recommended Value Default Why Healthy Threshold 1 3 Bring a recovered endpoint back into rotation after a single successful check Unhealthy Threshold 3 1 Require 3 consecutive failures before removing an endpoint — avoids flapping on transient issues Interval 15 seconds 15 seconds No change needed Jitter Percent 30% 30% Stagger health check timing across endpoints (30% of 15s = up to 4.5s offset) Key insight for jitter setting: When you have multiple endpoints in a pool, health checks without jitter all fire at the same instant that can create amongst other issues a temporary artificial network congestion or failure at endpoints. The 30% jitter setting randomizes the start time of each health check within a window (default: 15s interval with a 30% jitter, so checks are offset by up to 4.5 seconds). Leave this at the default unless you have a specific reason to change it. Advanced health check options: Host Header: Set to the value your application expects (do not leave blank if your origin validates the Host header) Path: Set a meaningful health endpoint like /healthz a common convention, but use whatever your application exposes Expected Status Codes: 200, 3xx Request/Response Header Manipulation: Add or remove headers as required by your application Expected http response: Validate the Raw Bytes expected in the Response of HTTP Health Check Origin Pool Display in UI: Routes: Routes are where your HTTP LB gains precision. Rather than sending all traffic to a single origin pool, Routes let you make forwarding decisions based on path, method, headers, and query parameters. They also expose per-route controls for timeouts, retries, header manipulation, and security policy controls that are not available at the origin pool level. Recommended Route Configuration: Route Type: Simple Route HTTP Method: Any Path Match: Prefix (use Regex or Exact match when you need more specificity) / Headers: Add header match conditions only if required Port Match: Adjust only if needed Origin targeting: Origin Pools:Add the Origin Pool(s) you configured in the previous section Host Rewrite Method: Automatic Host Rewrite (or set a specific value if your origin requires a fixed Host header) Query Parameters: Retain (Remove and Replace are available options) Route Activation: Enabled (Disable option) Advanced route options: Load Balancing Control: Use LB Hash Policy Priority: Default Origin Server Subsets: Leave unset unless subset routing is required Request/Response Manipulation: Header add/remove, cookie add/remove, set-cookie add/remove -configure as needed for your application Security (per-route overrides): WAF:Inherit from HTTP LB (recommended) or specify a different policy per route WAF Exclusion:Inherit from HTTP LB or specify an Exclusion Policy — see the note in the Gotchas section below on inline exclusions CORS and CSRF:Configure as needed Protocol Upgrades: SPDY:Disable (enable only if required) WebSockets:Disable (enable only if your application requires WebSocket support) Retry Policy: Key insight “retry values”: The retry settings below are tuned for typical HTTPS application traffic. The per-retry timeout of 1000ms prevents a slow origin from consuming the full route timeout on every attempt, and the retry interval backoff (25ms initial, 2500ms max) avoids hammering a struggling origin. Validate these values with load testing before going live. Custom Retry Policy Settings: Retry Conditions: 500 Gateway-error Connect-failure Refused-stream Reset Retriable-4xx Number of Retries: 3 Per-Retry Timeout: 1000ms Retry Interval: 25ms Max Retry Interval: 2500ms Miscellaneous Route Options: Route Timeout: 30000ms (30 seconds) Route-Specific Buffering: Common Mirroring: Disable Cluster Retract: Disable (validate with testing before enabling) Security Settings: Security configuration in F5 XC is layered. The settings below represent a solid baseline for an initial deployment. Individual applications will likely require tuning — use this as a starting point, not a final state. Web Application Firewall: The recommended starting posture is blocking mode with High and Medium attack signatures active. This catches the most common attack patterns while keeping false positive rates manageable. Do not start in detection-only mode and leave it there — establish a review cycle and move to blocking on a defined schedule. WAF: Enable Enforcement Mode: “Monitor” then after review migrate to “Blocking” Security Policy:Custom Attack Signatures: Default signature set High, Medium, and Low severity Automatic Attack Signature Tuning:Disable Automatic Signature Staging:Enable (7days) Threat Campaigns:Enable Violations:Default Signature-Based Bot Detection:Default Enhance with AI: Enable Mitigate High and Medium (have a review cadence) WAF Exclusion: Use a dedicated WAF Exclusion Policy object — do not use inline exclusions (see Gotchas below) Additional WAF-adjacent features — configure as needed for your application: Data Guard CSRF Protection GraphQL Inspection Cookie Protection API Protection: Enable as needed. If your application exposes a defined API surface, uploading an OpenAPI spec and enabling API Discovery is a worthwhile early step. Malware Protection: Disable DoS Settings: Mitigation Action: Block RPS Threshold: Typically based on Capacity of origin application endpoints Client-Side Challenge: Enabled if web based application Custom Service Policy for DoS: Apply a specific geo location and IPI during DDoS DDoS Mitigation Rules: Default Slow DDoS: Default Service Policies: Service Policies match on a set of criteria and apply an action. They operate at the connection level and complement WAF, which operates at the request content level. Service Policies: Apply Specified Service Policies (list any access restriction policies you need) IP Reputation: select the reputation categories appropriate for your threat model Threat Mesh: Disable User Identifier Policy: Create a policy using Client IP and TLS Fingerprint based on JA4 as identifiers (other identifier types are available) Malicious User Detection: Enable Malicious User Mitigation: Enable, Default settings Rate Limiting: Configure as needed based on expected traffic profile Trusted Client Rules: Configure as needed Client Blocking Rules: Configure as needed CORS Policy: Configure as needed Other Settings: VIP Advertisement: This is what makes the HTTP LB publicly reachable through the F5 Regional Edge network. If you change this to a Custom setting, validate your advertisement policy carefully as a misconfiguration here means no traffic reaches your LB. Advertise Internet Load Balancing Algorithm: Choose based on your application's session and traffic characteristics. Round Robin is the default and works for most stateless applications. If you have session affinity requirements, evaluate the hash-based options. Trusted Client IP: Disable unless you have a specific use case that requires preserving the original client IP through a proxy chain upstream of XC. Location Header: Enable “Add XC RE Ingress Location” to include the Regional Edge location in response headers. This is useful for troubleshooting and for understanding which RE node handled a request. Header and Cookie Options: Configure request/response header additions, removals, and cookie manipulation as required by your application. Error Response: Configure custom error response pages as needed. The default F5 error pages are functional but not branded. Most production deployments will want custom responses for 4xx and 5xx errors. Buffer Policy: Default: No buffering (requests are streamed to the origin) Max Buffer Size: 10,485,760 bytes (10MB) – if the request body exceeds this, XC returns HTTP 413 (Payload Too Large) Timeout behavior: If the full request body is not received before the timeout, XC returns HTTP 408 (Request Timeout) When to enable: Enable buffering if your origin cannot handle streaming request bodies, or if you are using WAF inspection on large POST requests Compression: Algorithm: GZIP only (not configurable) Compression Level: 5 (not configurable) Behavior: XC compresses responses dispatched from the upstream origin when the client signals support via “Accept-Encoding” Enable if your origins do not already compress responses and your client traffic includes browser-based users Idle Timeout: Default: Client Side - 30 seconds Behavior: A stream with no activity (upstream or downstream) for this duration is terminated with HTTP 504 Increase for applications with long-running server-sent events, streaming responses, or slow upload scenarios Common Gotchas: These are the issues that come up repeatedly in initial deployments. Check these before you go live. Using DNS-based origin targeting instead of IP + Host Header: By default Distributed Cloud rewrites the host header so validate and set appropriately. DNS-based origin targeting works but introduces a dependency on DNS TTL behavior that XC does override in non-standard ways. During a failover event, you may experience stale resolution longer than you expect. Use IP-based origin with Host Header wherever possible for predictable behavior. Not Configuring a Health Check at all or Leaving health check thresholds at defaults: By default, a health check is not added to an origin pool. Also, the default Healthy Threshold of 3 means a recovered origin must pass 3 consecutive checks before re-entering rotation. If your check interval is 15 seconds, that is 45 seconds of unnecessary exclusion for an endpoint that came back healthy. Set Healthy Threshold to 1. The default Unhealthy Threshold of 1 is the opposite problem a single failed check removes the endpoint. Set Unhealthy Threshold to 3 to tolerate transient blips. Attaching Origin Pools directly to the HTTP LB instead of utilizing Routes: The default Origin Pool field on the HTTP LB is a catch-all fallback. If you attach your primary origin there and do not configure Routes, you lose access to per-route retry policies, timeouts, header manipulation, and security overrides. Build your routing structure with explicit Routes from the start. Starting in WAF Monitor mode and never switching to blocking: Monitoring mode is a valid tuning step, but it is easy to leave it there indefinitely. Set a review date when you configure monitor mode. Establish your false positive baseline and move to blocking on a defined timeline. Not setting a Host Header on the health check: Leaving the Idle Timeout at 30 seconds for streaming applications: The 30-second idle timeout will terminate long-lived connections, WebSocket connections, server-sent event streams, slow uploads without warning. If your application uses any of these patterns, increase the Idle Timeout before testing.How I Did It: Simplifying BIG-IP Telemetry for Third-Party Observability Platforms
In this article, I introduce two community-supported projects designed to help customers get more value from BIG-IP telemetry. The BIG-IP Telemetry Streaming Validator and Configurator simplifies the deployment of Telemetry Streaming, while the BIG-IP Telemetry Exporter helps integrate BIG-IP metrics and logs into existing observability platforms such Grafana, Splunk, Elastic, Datadog, and other modern analytics ecosystems utilizing OpenTelemetry.Three Things I've Learned Recently While Deploying F5 CIS on OpenShift
Not every CIS deployment issue is actually a CIS issue. This article walks through three lessons learned from recent OpenShift deployments where the real culprit turned out to be NetworkPolicies, image selection, and version management rather than the controller itself.Migrate CDN Distribution to HTTP-LB Integrated One-Click CDN
You have an application on F5 Distributed Cloud (F5 XC) Content Delivery Network (CDN) in a service chained deployment model of CDN <-> HTTP-LB <-> Origin and want to migrate to the newly introduced HTTP-LB with integrated One-Click CDN. This guide walks through the process of being able to utilize the same Bring Your Own Certificate (BYOC) and domain from the CDN distribution to limit down time and make a smooth transition. Architecture Overview: Prior to the newly released HTTP-LB with Integrated One-Click CDN F5 Distributed Cloud CDN accommodated and still can accommodate multiple CDN deployment models with the 3 most common shown below: CDN to HTTP-LB Service Chain CDN closet to the end client and security services at HTTP-LB CDN to Origin CDN Side Car L7 Route off HTTP-LB or any Proxy to CDN distribution for a positive cache model or HA models between CDN providers The main take away is that you needed to configure a Proxy Layer (HTTP-LB) and a CDN Distribution layer, so 2 configuration objects within F5 Distributed Cloud or 3rd party platforms. With the recent announcement of Integrated One-Click CDN you no longer need to configure these 2 layers. This article will focus on migrating the CDN to HTTP-LB Service Chain model to the new F5 Distributed Cloud Integrated CDN model shown below. Requirements for Migration: Utilize the same Domain Name: Your applications FQDN (e.g. www.migration.example.com) Utilize the same BYOC Certificate that is applied to the current CDN Distribution: Inline Certificate Object Access to DNS record for CDN Distribution to lower DNS TTL Access to DNS record for CDN Distribution to change to HTTP-LB with integrated CDN Minimal Downtime Migration Process Steps: 1. Pre-Migration DNS: 24 Hours before migration we Lower the DNS TTL of the existing CDN distribution to DNS record (I set mine to 60 seconds). This should provide enough time for DNS TTL to globally propagate and then we rely on any Local DNS TTL to expire in path from Client to the Domain Name 2. HTTP-LB: Not including all the HTTP-LB configurations just the objects needed for the migration: Domain BYOC Inline-certificate CDN VIP Advertisement For other HTTP-LB settings please use your companies standard deployment methods and when needed work with your local F5 Sales Engineer Create a New HTTP-LB Utilize same inline certificate as current CDN Distribution Utilize same inline Domain of current CDN Distribution for the new http-lb www.migrate.example.com Enable Caching Set up cache policy or reuse existing cache policy rules as CDN Distribution Other Settings VIP Advertisement (This is why we can utilize the same domain and same BYOC. With F5 DIstrbuted Cloud HTTP-LB you can leverage the same Inline or Shared Certificate Object with the same domain across existing CDN distribution as long as the VIP is a different public IP. INTERNET SPECIFIED VIP Shared/IP Make sure the tenant has an additional VIP 3. DNS: Once the HTTP-LB is ready we can now migrate the DNS cname record of the CDN service name to the newly created HTTP-LB 4. Validate Traffic: At this point both the Old CDN Distribution and new HTTP-LB with One-Click CDN will be listening for traffic. After the DNS TTL expires and any Local DNS TTL or DNS cache expires the new HTTP-LB will be the only listener for the domain http://www.migrate.example.com 5. Decommission Old CDN Distribution: Once all traffic is utilizing the new HTTP-LB with integrated CDN you can delete the CDN DistributionAutomating F5 ADSP — Part 4: F5 XC and NGINX Gateway Fabric for Delivery and Security
What this use case demonstrates This use case deploys NGINX Gateway Fabric (NGF) on the Kubernetes Gateway API as the in-cluster data plane. WAF and API protection are provided by F5 Distributed Cloud (XC) at the edge. It covers all four ADSP areas: Delivery, Security, Deployment, and xOps. Delivery: F5 Distributed Cloud HTTP load balancer at the edge, NGF (running NGINX Plus) handling in-cluster delivery via the Gateway API. Security: XC WAF in blocking mode, XC API protection built from an OpenAPI spec, with validation and fall-through both in report mode by default. Deployment: XC consumed as SaaS, GKE Standard with private nodes, NGF installed via OCI Helm chart, the application deployed via a separate OCI Helm chart and exposed through a Gateway API HTTPRoute. xOps: The OpenAPI spec lives in the repo at config/uc4/app/oas/openapi.json. The OAS is the source of truth for API protection policy, change the spec, push, and enforcement follows. Architecture What gets deployed: A GCP VPC with a dedicated k8s subnet (with secondary ranges for pods and services), management subnet, and NAT for private nodes A GKE Standard zonal cluster with private nodes and a control plane locked down by authorized networks NGINX Gateway Fabric running NGINX Plus, installed from oci://ghcr.io/nginx/charts/nginx-gateway-fabric. The NGF control plane provisions a data plane Deployment and a LoadBalancer Service when the Gateway is created. Comfy Capybara deployed via oci://ghcr.io/knowbase/charts/comfy-capybara, exposed through a Gateway API HTTPRoute attached to the NGF Gateway An F5 Distributed Cloud HTTP load balancer with WAF and API protection. The origin pool is resolved from the NGF data plane LoadBalancer IP via Terraform remote state. The HTTPRoute splits traffic two ways: /api to the API service with a URL rewrite that strips the prefix, / to the frontend. DevSecOps in practice for UC4 The lead-in covers the approach. For UC4, that means: Terraform handles infrastructure, the GKE cluster, NGF, the application Helm release, and all F5 Distributed Cloud objects. No click-ops. State lives in a GCS bucket the workflow creates on the first run, with a separate state file per module. The XC origin pool reads the NGF data plane LoadBalancer IP from state/uc4/ngf, so no IP is ever pasted between configs. GitHub Actions runs the pipeline. Branch names trigger deployments, so git history shows what was meant to happen. GCP Workload Identity Federation replaces static service account keys. The XC API certificate, NGINX Plus JWT, and NGINX registry credentials live in GitHub Actions secrets, not the repo. The OpenAPI spec at config/uc4/app/oas/openapi.json is the source of truth for API protection. The workflow uploads it to the XC object store and binds it to the API definition. The pipeline Pushing to a branch runs the workflow. There is no manual terraform apply or helm install.

Why Origin Pool Health Monitors Prevent Outages
A single unhealthy origin can quietly turn into application errors, failed connections, and customer-facing outages. Health monitors help prevent that by continuously checking whether backend services are available and routing traffic only to origins that can successfully serve requests. For production deployments, configuring health monitors is one of the simplest ways to improve application availability, reduce operational risk, and protect the end-user experience. In short: if an origin matters to your application, it should be monitored.What’s new in F5 Insight for ADSP v1.2?

Single-click CDN Experience for F5 Distributed Cloud Load Balancers
Fundamentals The modern CDN has evolved well beyond cache and serve. Today’s platforms are intelligent edge fabrics that combine performance optimization, layered security, multicloud routing, and even workload execution at the edge. Few products embody this evolution more completely than F5 Distributed Cloud CDN, and this post explores both why CDNs matter and what sets F5’s newest approach apart. At its core, a CDN is a globally distributed system of edge servers, called PoPs or Regional Edges (RE), that cache content and handle user requests on behalf of the server origin. When a user requests a resource, DNS resolution routes them to the nearest PoP. If the resource is cached there (a “cache hit”), it’s returned immediately. If not (a “cache miss”), the PoP fetches it from the origin, stores it, and returns it to the user. The speed improvement isn’t just perceptual. Reduced Round-Trip Time (RTT) correlates directly with business outcomes. Every page load shaved makes a difference for search rankings, checkout completion, and ad viewability all improve with lower latency. CDNs don’t just make things faster; they make digital businesses more competitive. To put the difference in concrete terms, here’s how a typical 200KB page might deliver across different scenarios. Platform deep dive Traditional CDNs optimize for one thing: getting cached bytes to users fast. Distributed Cloud CDN starts there but doesn’t stop, it's engineered as a unified platform where content delivery, application security, multicloud connectivity, and edge compute converge under a single operational surface. F5’s approach is architecturally distinct Most CDNs are standalone services that organizations integrate with separate security tools, load balancers, and observability stacks. The operational overhead of stitching these together and keeping policies consistent across them is substantial. F5 takes a different approach: CDN is one capability within the broader Distributed Cloud Platform, meaning it inherits the platform’s DNS, load balancing, WAF, observability, and multicloud networking services. The practical result, noted by enterprise users, is that WAF rules, DDoS policies, and CDN configurations all live in the same console. There’s no context switching between vendors, no policy drift between your security tool and your delivery tool, and no blind spots at the handoff between them. In the newest product update, anyone already using a Distributed Cloud Load Balancer can enable CDN acceleration with a single click: no rearchitecting, no new deployments. Built-in cacheability insights estimate performance improvement and cost savings before activation, so teams can make informed decisions without guesswork. Target use cases: Where F5 Distributed Cloud CDN fits best There are three primary use-case families for enabling an integrated CDN: Secure apps everywhere (WAAP + CDN): Organizations that need comprehensive web app and API protection with WAF, DDoS, bot defense, unified content delivery under a single policy plane and management console. Modern digital experiences: Dynamic, personalized applications spanning multiple public clouds, edge locations, and on-premises infrastructure that need consistent delivery regardless of where origin workloads live. Multicloud & edge initiatives: Enterprises migrating workloads across cloud providers or deploying edge compute who need a platform that bridges delivery, security, and service mesh without re-platforming for each environment. Visibility & Control: You can’t optimize what you can’t see F5’s Distributed Cloud Platform ships with unified observability that spans delivery performance and security posture. Real-time dashboards expose traffic patterns, cache efficiency metrics, origin health, and security event timelines, all from the same interface used to configure policies. Cache efficiency isn’t a static attribute either. Distributed Cloud CDN provides granular control over cache keys, TTL values, and path or header-based caching rules, enabling teams to optimize hit rates for specific content types and access patterns. Cacheability insights indicate which web apps are candidates for acceleration. For security operations, the edge generates rich telemetry: request rates, blocked attack types, geographic traffic distribution, and bot classification outcomes. This feeds into the same observability layer as performance data, giving teams a single pane of glass rather than separate dashboards for CDN and security. The recently announced F5 Insight capability extends this further, bringing OpenTelemetry-powered observability across BIG-IP, NGINX, and Distributed Cloud Services, consolidating performance and security intelligence across an organization’s entire F5 footprint into actionable, unified visibility. Demo Walkthrough Final thoughts A CDN is no longer an optimization. It’s table stakes for any organization serving digital experiences to a geographically distributed audience. The question isn’t whether to deploy one, but which platform best aligns with the complexity of your architecture and the ambition of your security posture. For organizations operating at the intersection of multicloud delivery, API-driven applications, and enterprise security requirements, Distributed Cloud CDN represents a compelling architectural choice: a platform that treats performance and security not as separate concerns to be stitched together, but as integrated properties of the same edge fabric. The bytes will always need to get from somewhere to your users. F5 makes that journey faster, safer, and smarter.
