To reduce load on the app modules, the CDN caches all the content and delivers it to the user upon subsequent hits. When Arcadia Finance is front ended with the Distributed Cloud CDN, content no longer needs to be fetched by Frontend/Main every time the user accesses the page. In the context of CDN, we refer to this first case as a Cache-Miss. Only after the content has been successfully fetched by Frontend is the landing page finally presented to the user. The main pod then works to pull content from the backend, money-transfer, and refer-a-friend modules, all of which are available as different internal endpoints and virtual servers accessible only from other pods within the F5 Global Network. When a user accesses and logs into the Arcadia App, F5 Distributed Cloud CDN first screens each request and then passes it through to the backend, in this case, Frontend/Main. To support the above app, the following configuration has been added as a distribution in the Distributed Cloud Console CDN service: metadata:ĭns_name: ves-io-f85551e2-8a82-4fb4-88a4-b5c202e56d41.ac.vh.ves.io Refer-A-Friend is workload connected via F5 Distributed Cloud Customer Endpoint (CE) native to Google Cloud Service. Money-Transfer - IBM Cloud Satellite, OpenShift k8sįrontend/Main and Money-Transfer are workloads that run as pods in a k8s cluster on IBM OpenShift and are connected to the F5 Global Network using a Cluster-native k8s customer endpoint (CE), a workload managed by F5.īackend is a workload connected via F5 Distributed Cloud Customer Endpoint (CE) native to Azure. It uses independent modules that can live in multiple cloud providers and on different networks.įrontend/Main - IBM Cloud Satellite, OpenShift k8s Arcadia Finance is an example of a microservices app that we use at F5 to showcase new product features. Now, let's see an example of how we can use the F5 CDN to distribute a modern app. The centralized control plane provides both management and observability into specific application traffic and events across all the endpoints, including those on different network. Putting all the bits together, the F5 Distributed Cloud Console streamlines configuration for modern app types and API traffic (files, video, images), with integrated security control and advanced caching policies. From there, F5 provides global DDoS protection at OSI model Layers 3 through 7 with its consolidated DNS, and Web App and API Protection (WAAP). To do that, F5 uses its high-capacity global network to resolve DNS as close to that point as possible, and to direct clients to the closest regional point of presence. The first step for any CDN is to deliver content from the location closest to the point of origin. O Security, the fast-growing market segment More specialization – most CDN providers are now focusing primarily on:. A growing need to deliver application logic closer to consumers using standard software development pipeline and lifecycle management.Increased expectations for strong application performance, availability, uptime, and a robust security posture to support a user-focused experience.Stronger user-driven demand for personalized content, live streaming, on-demand video, and other dynamic elements.At F5, we see these trends grow by the day: If you're like me, you're probably wondering what's different in Content Delivery Networks today? Higher expectations and more specialization among providers. This is where F5 Distributed Cloud CDN breathes new life and adds color to readily accessible on-demand content. Modern apps now pull content from everywhere, and depending on how frequently the content is accessed, it doesn't make sense to pay a premium to have all of it always available within milliseconds. Most apps nowadays aggregate content from many sources, and many don't use the same internal networks or even one specific cloud provider.
