This presentation covers practical experience from building an OpenStack private cloud with a specific emphasis on high availability.
Based on a production deployment of OpenStack Grizzly at Pixelpark (a hosting company based in Berlin, Germany), we explore and explain
- highly-available data storage with Ceph,
- OpenStack service high availability with Pacemaker,
- virtual machine high availability in OpenStack Compute, and
- high availability considerations for OpenStack Networking.
We also outline the lessons a previously conventional hosting company has learned from moving to a private cloud deployment, both from a technical and organizational perspective.
About the speakers: Sebastian Kachel is an all-around devops guy at Pixelpark, and has been involved in the OpenStack deployment project since its inception. Florian Haas has provided consulting, training and guidance to Pixelpark over the course of the project.
