The OpenStack project is an open source cloud computing platform for all
|
|
types of clouds, which aims to be simple to implement, massively
|
|
scalable, and feature rich. Developers and cloud computing technologists
|
|
from around the world create the OpenStack project.
|
|
|
|
OpenStack provides an :term:`Infrastructure-as-a-Service (IaaS)` solution
|
|
through a set of interrelated services. Each service offers an
|
|
:term:`application programming interface (API)` that facilitates this
|
|
integration. Depending on your needs, you can install some or all
|
|
services.
|
|
|
|
The following table describes the OpenStack services that make up the
|
|
OpenStack architecture:

* - Service
|
|
- Project name
|
|
- Description
|
|
* - `Dashboard <http://www.openstack.org/software/releases/mitaka/components/horizon>`__
|
|
- `Horizon <http://docs.openstack.org/developer/horizon/>`__
|
|
- Provides a web-based self-service portal to interact with underlying
|
|
OpenStack services, such as launching an instance, assigning IP
|
|
addresses and configuring access controls.
|
|
* - `Compute <http://www.openstack.org/software/releases/mitaka/components/nova>`__
|
|
- `Nova <http://docs.openstack.org/developer/nova/>`__
|
|
- Manages the lifecycle of compute instances in an OpenStack environment.
|
|
Responsibilities include spawning, scheduling and decommissioning of
|
|
virtual machines on demand.
|
|
* - `Networking <http://www.openstack.org/software/releases/mitaka/components/neutron>`__
|
|
- `Neutron <http://docs.openstack.org/developer/neutron/>`__
|
|
- Enables Network-Connectivity-as-a-Service for other OpenStack services,
|
|
such as OpenStack Compute. Provides an API for users to define networks
|
|
and the attachments into them. Has a pluggable architecture that
|
|
supports many popular networking vendors and technologies.
|
|
* - `Object Storage <http://www.openstack.org/software/releases/mitaka/components/swift>`__
|
|
- `Swift <http://docs.openstack.org/developer/swift/>`__
|
|
- Stores and retrieves arbitrary unstructured data objects via a RESTful,
|
|
HTTP based API. It is highly fault tolerant with its data replication
|
|
and scale-out architecture. Its implementation is not like a file server
|
|
with mountable directories. In this case, it writes objects and files to
|
|
multiple drives, ensuring the data is replicated across a server
|
|
cluster.
|
|
* - `Block Storage <http://www.openstack.org/software/releases/mitaka/components/cinder>`__
|
|
- `Cinder <http://docs.openstack.org/developer/cinder/>`__
|
|
- Provides persistent block storage to running instances. Its pluggable
|
|
driver architecture facilitates the creation and management of block
|
|
storage devices.
|
|
* - `Identity service <http://www.openstack.org/software/releases/mitaka/components/keystone>`__
|
|
- `Keystone <http://docs.openstack.org/developer/keystone/>`__
|
|
- Provides an authentication and authorization service for other
|
|
OpenStack services. Provides a catalog of endpoints for all
|
|
OpenStack services.
|
|
* - `Image service <http://www.openstack.org/software/releases/mitaka/components/glance>`__
|
|
- `Glance <http://docs.openstack.org/developer/glance/>`__
|
|
- Stores and retrieves virtual machine disk images. OpenStack Compute
|
|
makes use of this during instance provisioning.
|
|
* - `Telemetry <http://www.openstack.org/software/releases/mitaka/components/ceilometer>`__
|
|
- `Ceilometer <http://docs.openstack.org/developer/ceilometer/>`__
|
|
- Monitors and meters the OpenStack cloud for billing, benchmarking,
|
|
scalability, and statistical purposes.
|
|
* - `Orchestration <http://www.openstack.org/software/releases/mitaka/components/heat>`__
|
|
- `Heat <http://docs.openstack.org/developer/heat/>`__
|
|
- Orchestrates multiple composite cloud applications by using either the
|
|
native HOT template format or the AWS CloudFormation template format,
|
|
through both an OpenStack-native REST API and a
|
|
CloudFormation-compatible Query API.
|
|
* - `Database service <http://www.openstack.org/software/releases/mitaka/components/trove>`__
|
|
- `Trove <http://docs.openstack.org/developer/trove/>`__
|
|
- Provides scalable and reliable Cloud Database-as-a-Service functionality
|
|
for both relational and non-relational database engines.
|
|
* - `Data processing service <http://www.openstack.org/software/releases/mitaka/components/sahara>`__
|
|
- `Sahara <http://docs.openstack.org/developer/sahara/>`__
|
|
- Provides capabilities to provision and scale Hadoop clusters in OpenStack
|
|
by specifying parameters like Hadoop version, cluster topology and nodes
|
|
hardware details.
