Server Redundancy
With this bad experience, I'm start thinking about server redundancy. Do you guys have a disaster recovery plan in place? if you do, how did you do it?
Ideally, when the 1st server is not functioning for whatever reason (the whole data center building collapsed/burnt down etc), I want my users to be automatically directed to the 2nd server at different data center.
In short, the 2nd server is acting as a hot standby for *all* services running on the 1st server (DNS, WWW, Email, FTP, MySQL, etc).
The next question is, how do you synchronize the data between the 2 servers? The assumption is my users always update/upload their data to the 1st server.
of course I don't want to break the bank, and I want this redundancy solution to be cost effective (look at it as an "insurance policy" for your webhosting business).
