The following list (Table 17-1) provides a brief description of each OpenStack service and the Heat
Orchestration program provided in the previous example. The identity, compute, and image
services are standard dashboard components. The other components are optional.
Details of the OpenStack system is out of scope for this document. Refer to the OpenStack
documentation for more details on these services and other OpenStack services, programs, and so
on.
Table 17-1. OpenStack Services
Service Name Service Type Description
Heat Orchestration Implements an orchestration engine to launch multiple
composite cloud applications based on templates in the form of
text files that are treated like code.
Horizon Dashboard Provides the Web-based user interface used to manage
OpenStack services (network, compute, image, block and object
storage, and identity).
Neutron Network Provides network connectivity between interface devices
managed by other OpenStack services, such as Compute.
Nova Compute Provides the ability to manage your computing resources, such as
CPU, memory, disk, and network interfaces.
This allows you to easily migrate workloads and run them at scale
with predictability, consistent performance, control, and visibility.
Glance Image Stores images from the compute service.
Swift Object Storage Provides cloud-storage software so that you can store and retrieve
data with an API (application programming interface).
Ideal for storing unstructured data that grows without bounds,
such as image files.
Cinder Block Storage Provides the ability to virtualize block storage devices
management and provide a self-service API for end-users to
request and consume resources without knowing where their
storage is actually deployed or on what type of device.
In our example, it stores volumes for the Compute service.
Tel emetry Ceilometer Monitors, collects, normalizes, and transforms data produced by
OpenStack services (network, compute, image, and block
storage).
Use this data to create different views to help solve telemetry
issues.
Keystone Identity Provides authentication (authN) and high-level authorization
(authZ) for the dashboard, network, compute, image, block
storage, and object storage services.
