I'd do something like this: - One frontend webserver proxying for those two PHP app servers (or more depending on load and availability of redundant connectivity) - MySQL taken out from those app servers and put in a separate server (in another duo probably so I can do replication/clustering) - If applicable, compartmentalize the PHP and web servers so they can be made into virtual machines later (e.g. if you want to throw it to EC2 or to a private cloud) Generally I'd spread the workload to more machines to reduce single point of failure (and allow for future extensions implementing HA.) As others have pointed out, there's quite a lot of HA/failover solutions out there, so you may have to evaluate a few to determine if they fit your requirements. -- Zak B.
