F5 Big-IP Competitors: Top 8 Alternatives 2023

You’ve probably heard the term “BIG-IP” used to describe F5® products if you’re familiar with the company. Many people are now confused about the function of F5 BIG-IP and what exactly it is. In this article, we will explain in layman’s terms what the F5 BIG-IP network is and who its competitors are.

F5 Big-IP Overview

A restriction in Red Hat OpenShift’s CNI prevents the pod’s IPs from being made available to third-party components like the Session Border Controller (SBC). As an SIP/RTP Application layer gateway, the F5 BIG-IP can help you get around this restriction. In order to connect the external components to the OpenShift cluster, an F5 BIG-IP is set up as part of the solution. The F5 BIG-IP is used to initiate VXLAN/GENEVE tunnels to the Red Hat OpenShift nodes. Each of the F5 BIG-IPs on the OpenShift cluster has its own set of host subnets that have been specifically defined.

One virtual server handles the SIP protocol, while the other handles the RTP/Media protocol for incoming calls. The host network contains the virtual server’s IP address, which third-party tools (like SBCs) can access with some straightforward routing. To ensure that all pod IPs accessible via VXLAN or Geneve tunnels receive an equal share of incoming traffic, the virtual server implements load balancing. When data exits the F5 BIG-IP, it undergoes network address translation, which changes the packet’s origin IP to one within the host subnet that the OpenShift cluster has designated. Configuring the virtual server with a message-routing SIP profile implements the SIP-ALG functionality.

Also, in order to connect the BIG-IP APIs with the Kubernetes APIs, a container component known as Container Ingress Services (CIS) must be used when integrating F5 BIG-IP with Red Hat OpenShift Kubernetes. Through VXLAN/GENEVE tunnels, the CIS component keeps tabs on the configured pods of namespaces and teaches the F5 BIG-IP how to translate IP addresses into MAC addresses for the pods. CIS uses the AS3 declarative API to automatically update the BIG-IP configuration whenever a user configuration is applied or a status change happens in the cluster.
