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 DistributionAppWorld LATAM 2026 - "Write Your First iRule" Contest
