I'm looking for resources that will help me design an optimum multi-user multi-server LAMP environment.
We currently have 7 servers (2 load-balanced webservers, 2 redundant clustered web-content servers, 2 redundant clustered MySQL servers, 1 VirtualMin Developer server), but am having difficulty determining if what I have done is common/optimum/good practice, etc.
Can anyone point me to any good/great resources for designing (and running) multi-server LAMP environments?
Note: I asked this question on StackOverflow some time ago, but didn't get any great results. Perhaps I should have waited until the end of the Beta (for more of a non-SO audience)
