Subject Re: Latency Comparison between cloud hosting Vs Dedicated hosting

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.
