The first section tells the story of why Netflix migrated to cloud, how we think about choosing AWS as our cloud supplier and what features of the Netflix site were moved to the cloud over the last three years.
The second section is a detailed explanation of the globally distributed Java based Platform as a Service (PaaS) we built, the open source components that we depend on, and the open source projects that we have started to share at http://netflix.github.com.
The final section talks about how we run these PaaS services in the cloud, and includes details of our million writes per second scalability benchmark.
If you would like to see these slides presented in person, I'm teaching a half day cloud architecture tutorial at Gluecon in Broomfield Colorado in May 23-24th. I hope to see you there...
