Asgard is a web interface for application deployments and cloud management in Amazon Web Services (AWS).
Asgard was the home of the Norse god of thunder and lightning, and it's where you go to control things in the cloud.
Netflix has been using Asgard for cloud deployments since early 2010. It was initially named the Netflix Application Console.
The project became open source on June 25, 2012, announced in this Netflix Tech Blog post.
Refer to the Quick Start Guide to get started setting up and using Asgard.
