OpenStack – Building and managing public and private cloud computing platforms
On June 11, 2014 by Liju Gopinathan
- Cloud
OpenStack is a free and open-source software cloud computing software platform. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. Currently, it is managed by the OpenStack Foundation, a non-profit corporate entity established in September 2012 to promote OpenStack software and its community.
Openstack family components :
- Compute (Nova)
- Object Storage (Swift)
- Block Storage (Cinder)
- Networking (Neutron)
- Dashboard (Horizon)
- Identity Service (Keystone)
- Image Service (Glance)
- Telemetry (Ceilometer)
- Orchestration (Heat)
- Database (Trove)
- Bare Metal Provisioning (Ironic)
- Multiple Tenant Cloud Messaging (Zaqar)
- Elastic Map Reduce (Sahara)
- Container Infrastructure Management Service (Magnum)
- Key Manager Service (Barbican)
| Service | Project name | Description |
| Dashboard | 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 | Nova | Manages the lifecycle of compute instances in an OpenStack environment. Responsibilities include spawning, scheduling and decommissioning of virtual machines on demand. |
| Networking | 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. |
| Storage | ||
| Object Storage | 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. |
| Block Storage | Cinder | Provides persistent block storage to running instances. Its pluggable driver architecture facilitates the creation and management of block storage devices. |
| Shared services | ||
| Identity service | Keystone | Provides an authentication and authorization service for other OpenStack services. Provides a catalog of endpoints for all OpenStack services. |
| Image Service | Glance | Stores and retrieves virtual machine disk images. OpenStack Compute makes use of this during instance provisioning. |
| Telemetry | Ceilometer | Monitors and meters the OpenStack cloud for billing, benchmarking, scalability, and statistical purposes. |
| Higher-level services | ||
| Orchestration | Heat | Orchestrates multiple composite cloud applications by using either the native HOTtemplate format or the AWS CloudFormation template format, through both an OpenStack-native REST API and a CloudFormation-compatible Query API. |
| Database Service | Trove | Provides scalable and reliable Cloud Database-as-a-Service functionality for both relational and non-relational database engines. |
