Benchmarking Cassandra Scalability on AWS - Over a million writes per second

We picked a write oriented benchmark using the standard Cassandra "stress" tool that is part of the product, and Denis ran and analyzed the tests on Amazon EC2 instances. The time taken by EC2 to create 288 new instances was about 15 minutes out of our total of 66 minutes.

Startup Lessons Learned

per-IP maintenance of SG’s across regions. Reserved instances purchased in EC2 classic do not automatically transfer, so don’t forget to transfer them (doesn’t cost anything). So, let your ACLs be permissive and ALLOW ALL and then DENY a specific IP address/range instead. Route53 has no support for “views” in VPC – a public DNS name that is seen via dig publicly with the public IP and private IP on the private network.

How To Bootstrap Your Startup

We are on the high end of the range, and I think expecting less would be unrealistic unless you are building something really simple (and therefore with limited inherent IP).
