This talk is for anyone who is considering whether OpenStack needs Queuing and Notification services as part of it, or anyone who is building applications on top of OpenStack and is finding these missing (esp as compared to AWS)
Comcast is a member of the OpenStack Community.Comcast also is a strategic collaborator with Cisco on OpenStack.This collaboration with Cisco is focused on getting Comcast's own applications to run on its own private OpenStack infrastructure.The intent is to share the results of this effort with the OpenStack community as open source.We are not disclosing which applications will run in the Comcast OpenStack environment at this time. However, we expect a wide variety of Comcast applications to be targeted.The expected result will be contributions to the OpenStack open source community that will enable OpenStack to become solid, scalable, and reliable infrastructure for service providers like Comcast.
