Hi Sujatha, You should really do the same stuff to improve latency in the cloud as what you would do on a dedicated server. Amazon-specific stuff: Bigger EC2 instances have better IO. EBS performance varies. Some people mount N of them and stripe across them. Some people try N EBS volumes to find the best performing one(s) and discard the rest. Some people pay for provisioned IOPS.
