We repeat an introductory presentation on the OpenStack project, as many of our new members have asked to receive a complete overview. During this presentation we shall visit the different components and provide a high-level description on the architecture of OpenStack software. We shall also refer to the community around the project and as usual discuss any issues posed by the attendees. This is a great chance to get to know better the internals of OpenStack, so i highly recommend to share with any interested party.

1. Project: OpenStack

2. The mission
“to produce the
ubiquitous Open Source Cloud Computing platform
that will meet the needs of public and private clouds
regardless of size, by being simple to implement and
massively scalable”

3. The character
•
•
•
•
Complete open-source IaaS solution
Open everything
Python written
Community powered
•
•
•
•
Scalability: shared nothing architecture
Diversity: Plugins and drivers
Quality: Code reviews / Continuous Integration
Support: Bugs and Blueprints
OpenStack = Code + Community
