Folks, I am getting really tired of people bashing the cloud by saying things like “Amazon’s outage in third day: debate over cloud computing’s future begins”. People need to understand that the cloud is not some magical place you put your applications into and never have to worry ever again. There are always a bunch of servers in racks somewhere or some power lines going to the data center, and there is always a driver that can run

I was playing around with Amazon RDS today. It’s a web service that makes it easy to set up, operate, and scale a relational database in the cloud.

All this experience makes for a great book for anyone who wants to

I just finished reading Cloud Application Architectures by George Reese. It’s good reading for folks that are just getting into cloud computing but are already somewhat technically savvy around systems engineering. The book is focused on AWS, as it's the prevalent and most feature-rich public cloud out there. It’s a good primer for folks getting started with AWS and has some cool AWS command line tool examples and goes over some of the AWS services and concepts. The
