I have 15 databases that are running off my shared hosting account for $5/mnth. I would like to use AWS RDS.
1) Do I have to create a new INSTANCE for each database?
2) Won't this be expensive $191/mnth ($12.75/mnth x 15DBs for the cheapest db.t2.micro instance)? http://aws.amazon.com/rds/pricing/
3) How can I optimize the management of resources? (eg. Is putting more tables into a single DB instance the best solution?)
