Eric Williams (Rackspace) - Using Heat on OpenStack
The document provides an overview of OpenStack's orchestration service, Heat, focusing on its role in managing infrastructure and applications in OpenStack clouds. It highlights Heat's features such as infrastructure as code, autoscaling, and service management, along with its comparison to configuration management tools. Opportunities for improvement and ways to get involved with the OpenStack community are also discussed.

Editor's Notes
- #5 Before discussing Heat, a word about openstack Run your own cloud, enough said. OK, not enough said: Open-Source Cloud Computing platform founded by NASA and Rackspace; behind some of the largest public clouds: Rackspace, HP, Also currently the private cloud of choice (compare maybe to Eucalyptus a few years ago, gauge the audience); huge opensource community, gigantic momentum.
- #8 Heat’s logo isn’t to my taste, so I grabbed something prettier from Openclipart.org (Public Domain). * Upstream project; service orchestration;
- #10 Heat gives provider-side access to infrastructure; In Rackspace’s implementation, all of these things are included. YMMV, because OpenStack administrators decide what is and is not available to their heat users.
- #12 Heat is about turning this (1) into this (2). Predictable, repeatable, extremely simple. Includes all the benefits of SCM: Versioning, Diff, test/dev/prod workflows
- #19 New DSLs seem to be the answer to all challenges these days: Chef, Puppet, Heat, you name it, *JUST MY OPINION, I MEAN NO OFFENSE Integrating with existing Chef or Puppet client-server infrastructures is doable, but should be easier. Upcoming Resource types for other integration points should resolve this Dealing with Failure is possible, but fiddly Reacting to failed nodes and services exposes the manual nature of integrating with existing integration points; self-healing is on the roadmap. better Scaling policies and newer resource types could address this
- #20 Integrates awesomely with OpenStack, because it’s official. Mention ceilometer. Focuses on Orchestration, leaving config management to the experts
