Compute ("Nova") provides virtual servers upon demand. Compute resources are

accessible via APIs for developers building cloud applications and via web interfaces for

administrators and users. The compute architecture is designed to scale horizontally on

standard hardware, enabling the cloud economics companies have come to expect.

Network (Neutron") is a pluggable, scalable and API-driven system for managing

Jawdat2012 18

ne wor s an a resses. e o er aspec s o e c ou opera ng sys em, can e

used by administrators and users to increase the value of existing datacenter assets.

Block Storage ("Cinder") provides persistent block storage to guest VMs. This project

was born from code originally in Nova (the nova-volume service described below).

Dashboard ("Horizon") provides a modular web-based user interface for all the

OpenStack services.


19/40

Object Store ("Swift") provides object storage. It allows you to store or retrieve files

(but not mount directories like a fileserver).

Image ("Glance") provides a catalog and repository for virtual disk images. These disk

images are mostly commonly used in OpenStack Compute.

Identity ("Keystone") provides authentication and authorization for all the OpenStack

Jawdat2012 19

serv ces.

Orchestration (Heat) orchestrates multiple cloud applications using the AWS

CloudFormation template format, through both an OpenStack-native REST API and a

CloudFormation-compatible Query API.

Metering (Ceilometer) monitoring and metering framework using an agentless from

3rd party systems, all is natively implemented in OpenStack.
