We run about 100 domains on two apache servers (two physical machines, one Apache process each)
Each domain is configured to go explicitly to one server or the other and that set up is fine, except when there is a hardware issue.
If we need to direct all traffic to one server, we need to do it via DNS and that takes a long time to propagate.
We're in the process of converting the two machines to Virtual Machines, but I would still like a bit of flexibility in terms of Apache configuration.
NOTE: we don't want round robin between servers, requests for a domain should go to a single machine unless asked to change.
I was thinking about a hardware solution, but I'm not sure what they cost and whether they will do what we want.
My preferred solution may be to set up a thin VM that provides a single front end for all requests and directs (per virtual domain name) to an internal apache server.
or am I missing something?
