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.

  2. 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. 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
  4. 4. Official programs • • • • • • • • • Compute (Nova) Object Storage (Swift) Image Service (Glance) Identity (Keystone) Dashboard (Horizon) Networking (Neutron) Block Storage (Cinder) Telemetry (Ceilometer) Orchestration (Heat) Incubation • Oslo (common libraries) • Infrastructure • Documentation • QA (tempest) • Database Service (Trove) • Bare metal (Ironic) • Queue service (Marconi) • Data processing (Savanna) • Deployment (TripleO) • Devstack • Release cycle management OpenStack Programs are reviewed by the Technical Committee to become official
