Hi David,
The answer: it depends.
So, I've set up a public testing instance on a micro-instance on EC2, all
pieces on that same server. I followed the Aaron Helton guide. It was
really easy and quick. My experience of using a micro instance is that its
under-powered for this. Fine for a cheap testing instance though.
One of the main draws of the Amazon stack is all the goodies that Amazon
throws in. So: manage your own database backups, or have RDS-Postgres do it
all for you, it depends on if you want to deal with doing it yourself. The
Amazon Linux AMI allows you to yum install everything you need too (java,
tomcat, apache, mvn, ant).
I think you can probably start off on a single instance that has all of the
DSpace components on the same instance (Apache, Tomcat, Postgres,
Solr/Elasticsearch). However, for our production setup, we have distinct
vm's (on our own local data-center) for each component, which has helped us
to scale better. When we had all of these on one box, its hard to diagnose
exactly what thing is causing the CPU to spike to 100% for a few minutes.
If you have the funds to do so, and your starting fresh, it might make
sense to go with the architecture you want, as opposed to having to deal
with a migration shortly down the road.
