Grid Computing Grid computing is the easiest application architecture to migrate into the cloud. A grid computing application is processor-intensive software that breaks up its processing into small chunks that can then be processed in isolation. If you have used SETI home, you have participated in grid computing. They collect volumes of data that subsequently need to be processed to search for a nonnatural signal that might represent attempts at communication by another civilization. It would take so long for one computer to process all of that data that we might as well wait until we can travel to the stars.

Cloud Application Architectures. This is a great book on how to build apps in the cloud! I was happy to see how much depth it went into. It is thorough. Finally, George Reese is a good writer! This is how he covers so much ground with so much depth in so few pages, and it all makes sense. For a technical book, it has an amazing narrative flow.

The book begins with an intro to cloud computing in general, with definitions and an explanation of different models, plus cost estimates of traditional IT, managed hosting, and cloud computing for an app. This book is mostly about Amazon, and states that up front. I was happy that the author brought in people to write those, instead of doing it himself. They are non-promotional in nature, and quite short.

That adds value to the book, which would have been fine without them, honestly. Here we also start to see a focus on the platform as a whole—availability zones, security, redundancy, reliability. These topics are treated fairly and woven into every chapter. Chapter 3 picks all this up again: considering a move into the cloud? More cost comparisons, more explanations of concepts such as availability and how they translate into the Amazon cloud. Performance, disaster recovery and a few other topics show up here.

Chapter 4 is about how to build an app in the cloud: web app design, making multiple machines work together, handling failure, building AMIs, privacy, and operating databases especially MySQL in the cloud. The privacy section is particularly good. And as I said already, this is one of the types of things he weaves into the whole book. And then Chapter 6 is on disaster recovery: planning, implementing, managing.

It starts with capacity planning. I saw that he was a tech reviewer for this book, too. It also talks about how you scale vertically in the cloud. Well, not a lot really. I read every word in this book, I promise. Nobody knows how much excess capacity Amazon has, and as we know, weird things happen. This book is the first one to go onto my list of essential books in a while. I write about topics such as technology, mindfulness, and fitness, and I tweet at xaprb.
