We have 4 WFE servers farm, For load balancing, I can see following option.
- Purchase the F5 load balancer, don't use the RM.
- Have a one more server that will do Routing using RM and caching. Don't use the F5 load balancer.
- Have both F5 load balancer and RM
I am wondering what approach we should take. I have read a lot of articles in MSDN, all suggests that we should have a routing & caching layer at front of WFE server. Considering we have just 4 WFE Servers do we need to have a separate routing and cache layer along with F5 load balancer. I am really confused
