Managing Open Source Releases of a Cloud Platform

Cloud Computing
Location: Portland 251

Tropo is a cloud communications platform for voice, SMS, and IM. In addition to the hosted service, we have opened the source of the core platform. In this session, we’ll talk about the lessons learned from running a cloud service and a parallel open source project. We did a lot wrong, and we got many things right. We’ll discuss what we’ve learned about product management, release management, marketing, and third party licensing.

  • Source Control – How we sync our internal source code with our external open source repository
  • Release management – How testing, releases, and change notifications differ between hosting and open source. Releases to one lag behind the other, so how do you manage that?
  • Marketing – How do your open source offerings affect the cloud offerings? Should you market them both through the same web site?
  • Licensing – If your cloud product contains services, features, or technologies that are licensed from third parties, how does your open source release cope?
