load balanced configuration

[Taylor, Kaia]

What extent of writing will the servers be doing?
a) mostly read-only - eg: two web servers that get the same content
updates once in a while, but not every minute), or 
b) writing too -- eg: will there be data written on a fairly constant
basis to either web server, that will then have to be shipped over to
update the other web server?
 
What kind of load balancing solution are you planning on?
(Some load balancing solutions are themselves single points of failure,
so you may need to consider redundancy with that)

Subject: load balanced configuration




Hi Plug,

I am considering combining the sites on two servers and creating a load
balanced configuration.  One server will be in one data center and
another will be in a different data center.  This is to ensure if one
data center goes off line that these site will still be available via
the Internet.  This is also a consideration for backing up our data and
content.  Each server is configured with a RAID 1 disk set.

I have never taken on such a responsibility so I am not sure of any
gotchas or anything I should be considering.

Our data center guy will be doing most of the work, which will help.  

Any suggestions or concerns I should have with two servers in a load
balanced arrangement with each server in a different location?

Thank you for your help!
