A few days ago, Tsuru got some attention in the news. After reading about Tsuru, and seeing some of its capabilities, people started asking for a way to try Tsuru. Well, your claims were attended! We're preparing a public cloud that will be freely available for beta testers.
TL;DR: go to tsuru.io/try, signup for beta testing and get ready to start deploying Python, Ruby, Go and Java applications in the cloud.
