Sounds like the AWS architecture caused Netflix to write better code ( read: more durable, more fault tolerant ). Less assumptions baked in the code, and it will be easier to port it to a new data center/cloud architecture if AWS doesn't meet their needs. As Netflix continues to scale, these changes will make managing that growth much easier. A lot of you seem to take this post as being negative against AWS architecture. I take it more as a good collection of common things that you need to watch out for in distributed environments, specifically the dangers of assumptions within your current infrastructure which may change dramatically as you scale.
