F5 Distributed Cloud (XC) is a SaaS-based platform that enables Network and Security services in data path to your application. If customer desires to add also custom Security services in the data path, customer will deploy Platform as a Services (PaaS), a container based solution.

This folder shares some typical customer use cases of PaaS:

First, a quick introduction to F5 XC:

Application Delivery Network (ADN)

F5 XC Application Delivery Network (ADN) is a Virtual Backbone that interconnects clients and services to be consumed by them. Edges of F5 XC ADN are:

  • F5 Regional Edges (RE): F5’s Points of Presence, based hardware managed by F5

  • or/and Customer Edges (CE): Customer’s Points of Presence (or site), based hardware managed by customer or by a Cloud Service Provider

Interconnections between Edges, as described here , are:
  • F5 private backbone: REs are interconnected using a multi-terabit, dedicated and redundant private backbone for maximum performance. These PoPs are densely peered and connected with multiple Tier1 transit providers to deliver high-quality internet access for applications and consumers. REs are directly connected to multiple cloud providers from these locations to provide a reliable and predictable experience across cloud providers.

  • Tunneling: REs-CEs and CEs-CEs are interconnected using tunnels IP over IP, IPsec or TLS depending on the trust of the underlay network.

Edges have the same software that provides Network, Security and K8S services managed in F5 XC Console.

Virtual Load Balancer (LB)

A Virtual Load Balancer - like a Virtual Server in F5 BIG-IP - is an object that is listening on a Virtual IP + Protocol + Port + FQDN and somewhere (Internet, interface of a CE or a K8S namespace). Once traffic is matched, Network and Security services are applied on the TCP session or the HTTP transaction. Then the traffic is Load Balanced to a pool of origin servers.

Platform as a Service (PaaS)

If customer wants to apply custom traffic management - like an iRule in F5 BIG-IP that could do “everything else” - or add a specific security protection that is not proposed by F5 XC, it’s possible with Platform as a Service feature.

Because ADN is one giant Kubernetes cluster, named Virtual Kubernetes, F5 XC is designed to execute containers in a pool of edges, named Virtual Site. These containers can be :
