This is a simple way to backup your MySQL tables to Amazon S3 for a nightly backup - this is all to be done on your server :-)
Sister Document - Restore MySQL from Amazon S3 - read that next
this is for Centos 5.6, see http://s3tools.org/repositories for other systems like ubuntu etc

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
