Use Cases and Deployment Scope
We use BIG-IP for load balancing wherein we have pool members behind that particular VIP address and the entire traffic comes to the VIP. Then, depending on the policy, whatever we configure, the traffic gets directed to the backend pool members. Obviously it's a security reason as well. Why we use F5, we don't want to expose directly our servers to the traffic and obviously the major use case for us is for remote VPN users who remote in using F5 BIG-IP client and then they get onto the office network or corporate network. And then nowadays it's almost everyone is working remotely, so we heavily rely on BIG-IP.
Alternatives Considered
F5 BIG-IP Local Traffic Manager (LTM) and F5 Distributed Cloud WAF (Web Application Firewall)
