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”

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

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

What about Amazon WS

OpenStack project Amazon Web Services

Virtual Machines Nova EC2

Block storage Cinder EBS

Object storage Swift S3

Virtual Networks Neutron VPC

Graphical User Interface Horizon AWS Management Console

• Every official program provides core functionality to operate a cloud infrastructure

• Glance provides disk image registry services and Keystone authentication and authorization functions
