My main use case for F5 BIG-IP Virtual Edition is mostly for application hosting, load balancing, and reverse proxy.
A specific example of how I use F5 BIG-IP Virtual Edition for application hosting, load balancing, or as a reverse proxy is that we had limited sets of IP addresses for the public and multiple applications—around more than 100. We didn't have 100 public IPs for each application, so using F5 BIG-IP Virtual Edition, we used only one virtual server, and behind that, we were able to take all the 100 applications. Basically, using one public IP, we are hosting all of our 100 applications, which is a lot of cost saving and also less overhead on the administration side. This was one of the use cases for which we have used F5 BIG-IP Virtual Edition.
I have a few other use cases for F5 BIG-IP Virtual Edition where there was a requirement for a persistent session to be implemented to have the proper load balancing and maintain the session with the back-end server, and we have a few applications that use this persistence feature. Apart from that, we are also using the WAF on top of our virtual edition of F5 BIG-IP Virtual Edition as a part of the security enhancement and application security requirements.
