Re: Kafka on EC2
I'd only consider m1.xlarge and higher for Kafka. The m1.xlarge have "high" I/O performance according to Amazon. This is disk I/O and network I/O performance. Of course you need to use EBS volumes if you want your Kafka brokers to survive reboots - you can expect reboots on AWS. Some people have reported I/O improvements by RAIDing EBS volumes (http://alestic.com/2009/06/ec2-ebs-raid). Deploying in the same region as your application will also improve performance.
