Pat Helland is a really smart guy. He was Platform Architect at Microsoft (big-picture strategy), then spent a couple of years at Amazon.com helping the company with its service-oriented-architecture (SOA) strategy. In March 2007 Pat rejoined Microsoft to become a part of the company’s Developer Division.
He recently has worked on the projects like:
- Bing Infrastructure.
There is a blog
Pat authored a set of extremely interesting and thoughtful papers:
- Life Beyond Distributed Transactions: An Apostate's Opinion
- Memories, Guesses, and Apologies
- Building on Quicksand
These papers help to shape understanding and body of knowledge in building massively scalable systems. It's strong recommendation to read these if you are studying CQRS and xLim or simply building solution for the cloud computing environment.
