Redis vs MySQL vs Tokyo Tyrant (on EC2)

September 29th, 2009

So, the question I am trying to answer is “roughly how much performance can we gain from using Redis for storing simple data instead of MySQL?”. Then it is up to you to look at all the differences and decide whether it is worth pursuing a switch to Redis.

ec2-consistent-snapshot: Creating Consistent EBS Snapshots with MySQL and XFS on EC2

September 29th, 2009

The name of the new program is ec2-consistent-snapshot.

Over the last year as I and my co-workers have been using this code in production systems, we identified a number of ways it could be improved.

A Scalable DNS scheme for Amazon’s EC2 Cloud

September 28th, 2009

One of the fundamental issues to deal with while building out my company’s cloud deployment was the need to assign our own hostnames to our instances. To accomplish this, we needed some sort of internal dns solution.

Each Amazon region has it’s own private class A ip range, to which the instances are NAT’d, and public class B’s.
