Provide persistent block storage for CVM. The plug-in-driven architecture facilitates the creation and management of block storage devices.

Shared service

Identity service

Keystone

Authentication and authorization services are provided for other Openstack services. Provides an endpoint directory for all Openstack services.

Image service

Glance

Store and retrieve virtual machine disk images. OpenStack computing will use it when the CVM stores it.

Telemetry

Ceilometer

Provide display and metrology costs, specimen management, scalability and statistical purposes for the OpenStack cloud.

Higher level of servic

Orchestration

Heat

Coordinate multiple composite cloud applications by using native hot template format or AWS CloudFormation template format, through OpenStack's native REST API and CloudFormation compatible query API.
