Component

Description

Nova (compute resource management)

Manages compute resources for VMs; coordinates and manages storage, images, and network resources.

Neutron (network resource management)

Manages network resources for VMs and handles data forwarding to and from VMs, allocates port resources, configures IP addresses and layer-2 interconnect resources (including VLAN and VXLAN), and provide layer-3 routing capabilities for VMs.

Cinder (block storage management)

Provides persistent block storage services that provision storage resources on demand through unified interfaces; allows connection to different types of backend storage via storage drivers.

Swift (object storage management)

Provides a scalable, redundant storage system. By adopting a fully symmetrical, resource-oriented distributed architecture, Swift ensures that all components are scalable and enhances service availability by eliminating single points of failure.

Glance (image management)

Provides VM image query, upload, and download services.

KeyStone (identity management)

Provides a central identity management mechanism in the OpenStack framework, including authentication, service rules management, and token management. It implements the OpenStack identity API.

Heat (service orchestration)

Orchestrates multiple complex cloud applications using templates through OpenStack APIs.

Ceilometer (telemetry)

Measures and monitors resource usage.

Ironic (bare metal server provisioning)

Provides a number of APIs for physical machine management. It is able to manage physical machines with no OS installed, covering powering on of physical machines, installing OSs for physical machines, and removing physical machines for repair.

Service OM

Provides cloud service O&M capabilities.

Virtualized pool

KVM compute nodes are connected to cascaded FusionSphere OpenStack systems to provide virtualized pools.

Bare metal server pool

Bare metal server compute nodes are connected to cascaded FusionSphere OpenStack systems to provide bare metal server pools.

Block storage pool

Block storage devices are connected to the cascaded FusionSphere OpenStack systems to provide block storage pools.

Network resource pool

Network nodes provide network resource pools.
