Redundant and Load Balanced Apache across a WAN!
Posted on 2008-09-29
Hi, and thanks in advanced for any help given.
I currently have a scenario where i have a web site that has grown considerably and requires some sort of redundancy prefereably across a WAN connection in to a datacenter in Sydney and Melbourne.
I have looked at alot of the posts here regarding this and they leave a few questions unanswered in my mind. So before you direct me to already answered questions please remember I have looked around. Unless you think i may have missed it.
My Scenario is simple or i would have thought! I need to have a server that i need Apache, and MySQL replicate to another server in another data center and if one is down the other serves the pages. Ultramonkey it seems can offer load balancing and with 4 nodes can achieve this high availability. What i cannot seem to find is information about setting up Ultramonkey across a WAN, all the documentation is for a local setup. Which in my mind has a single point of failure with the internet connection. I need a solid setup that can handle a dropout in either dc and just keep going with minimal transition time.
I find it hard to think that this isn't an extremely common scenario.
Maybe im missing something that a bit of discussion will sort out.
