I know there are users that use aws with geoserver but I don't really have
any reference sites off hand. That said I do have some experiences with
setting up geoserver on aws.
The biggest pitfall I have to say is the disk depending on how you set up
your amazon images and how much data you need to serve. If you are going to
serve any serious volume of data (be it vector or raster) you
will undoubtedly need to use an EBS volume to avoid losing data. EBS being
network storage which is slow and unreliable.
To get around this people typically RAID together a number of EBS volumes
which makes things more resilient to both the poor performance and the
unreliability of the network storage. I have seen people successfully create
huge databases (all of osm) with this scheme. There are scripts available
from various sources online to automate building fo the RAID.
And finally instances with lots of memory work best. The more the better.
Again because this allows postgres and the OS to cache more data in memory
and save accesses to disk. I have not experimented in specifically but if
serving lots of coverage data in geoserver the more memory that can be given
to the jai caches follows the same principles.
Hope that helps.
