OpenStack Services:

• Building blocks of the cloud and the OpenStack services:
  • Core services
    • Identity Management (Keystone)
    • Image Service (Glance)
    • Compute Service (Nova)
    • Networking Service (Neutron)
    • Block Storage Service (Cinder)
  • Other services:
    • Telemetry Service (Ceilometer)
    • Load Balancing-as-a-Service (Octavia)
    • Object Storage (Swift)
    • Orchestration Service (Heat)
    • Database-as-a-ServiceTrove
    • Bare Metal-as-a-Service (Ironic)
    • Shared File System (Manila)
    • DNS-as-a-Service (Designate)
    • Key Management (Barbican/Castellan)
  • OpenStack clients
    • Web Interface (Horizon)
    • CLI clients (python-openstackclient, python-serviceclients)
    • REST API
    • 3rd party integrations (Terraform, Ansible)
