we are currently developing a high traffic rails application with facebooker (facebook game). since amazon simpledb (aws-sdb) is really slow, we are thinking of using a dedicated mongodb server as offered by mongoHQ for example.
questions:
- what is the read/writes peak value for a mongodb server running on a amazon ec2 instance?
- what would be a recommended setup for a ec2 hosted app with mongodb - a master on amazon EBS and replicas on the ec2 instances? any examples or experiences?
- is there a company that offers mongodb hosting in the cloud?
thanks, mz
