F5 - is it just a reverse proxy (as far as fronting 100 webservers)

Also, just a personal observation: If you are fronting 100+ web services, I very much recommend:

1) Creating a dynamic type of origin server pool (e.g a phantom pool consisting of 100s of fallow members that can be dynamically populated)

2) A heterogeneous server arsenal (e.g a team of Ngninx Servers JUST for content that lives under /images, a team of Apache Servers for .js content, a team of Microsoft for asp[x], etc)

THESE are the type of things you can do with [only] F5, and play to it's strengths.
