DESCRIPTION
Speaker: Joe Sondow Asgard is a free and open source Grails application built and used by Netflix to deploy code changes and to manage resources in the Amazon cloud at large scale. In this talk we'll delve into how Asgard works, covering topics such as: Open source motivation, presence, and support. Tour of the user interface. Customizing Asgard for your own company. How Netflix philosophies drive Asgard's design. The Netflix Cloud Model. Easy large deployments and fast rollback. Caching the cloud with Groovy. Visual language for the cloud. Publishing a REST API. Mocking AWS for offline testing. Comparison with the AWS Management Console.
