Hello GeoServer Users,

I wanted to ask you for some advice regarding memory allocation for a
simple Web mapping service based on PostGIS, GeoServer and
OpenLayers/GeoEXT.

By simple in this case  I mean serving maximum 5-10 WMS layers,
getFeatureInfo, and getting legends. Underlying dataset will consists of
~3000 polygons of administrative areas. It will be hosted on cloud VPS -
either AWS or rackspace.

I have two questions regarding this setup:

1. Does it make sense to keep PostgreSQL and Geoserver on two separate
instances? Or is it better to focus on one, more powerful server.

2. Cloud servers will be scalable. So assuming 100 is the total amount of
memory available - what would be your suggestions of setting memory
parameters in PostgrteSQL? And how about java memory allocation for
GeoServer?

Thanks a lot for help,
Radek
