• Beta community projects: Profile tool, Cloud launcher

Community projects: Profile tool and Cloud Launcher

The profile tool and cloud launcher are beta open source projects that we have recently kicked off on github.  These projects are nascent at this point and we are looking for more people to get involved and help get them going.

• Profile Tool: The idea behind the profile tool is to provide access to a library of community created profiles on github, such as Ruby and Android, to quickly set up your development environments and tool chains.
• Cloud launcher: The cloud launcher enables you to create “microclouds” on your laptop, simulating an at-scale environment, and then deploy that environment seamlessly to the cloud.  Today the launcher utilizes Linux Containers to model your environment on your laptop and then uses Juju to jettison that environment to the cloud.  The launcher project on github allows for community expansion on this concept using different technologies and approaches.
