In 2011, developers of the Ubuntu Linux distribution adopted OpenStack with an unsupported technology preview of the OpenStack "Bexar" release for Ubuntu 11.04 "Natty Narwhal".
Ubuntu is the most popular operating system for the cloud, and is the reference operating system for OpenStack.

Cloud computing

OpenStack is a free and open-source software platform for cloud computing, mostly deployed as infrastructure-as-a-service (IaaS), whereby virtual servers and other resources are made available to customers.
In July 2010, Rackspace Hosting and NASA jointly launched an open-source cloud-software initiative known as OpenStack.

HPE Helion

In May 2014, HP announced HP Helion and released a preview of HP Helion OpenStack Community, beginning with the IceHouse release.
HPE Helion is based on open-source technology, including OpenStack and Cloud Foundry.

Nebula (computing platform)

NebulaNebula platform
The early code came from NASA's Nebula platform as well as from Rackspace's Cloud Files platform.
One application Open Sourced by NASA and developed by the Nebula project, 'nova' became one of the two founding projects of the OpenStack project.

This report is contradicted in part by remarks made by Ames Research Center CIO, Ray Obrien.
In July 2010, NASA CTO Chris C. Kemp open sourced Nova, the technology behind the NEBULA Project in collaboration with Rackspace, launching OpenStack.

LIO (SCSI target)

LIOLIO Linux SCSI TargetTarget
In addition to local Linux server storage, it can use storage platforms including Ceph, CloudByte, Coraid, EMC (ScaleIO, VMAX, VNX and XtremIO), GlusterFS, Hitachi Data Systems, IBM Storage (IBM DS8000, Storwize family, SAN Volume Controller, XIV Storage System, and GPFS), Linux LIO, NetApp, Nexenta, Nimble Storage, Scality, SolidFire, HP (StoreVirtual and 3PAR StoreServ families) and Pure Storage.
It is included in most Linux distributions; native support for LIO in QEMU/KVM, libvirt, and OpenStack makes LIO also a storage option for cloud deployments.

Infrastructure as a service

infrastructure as a serviceIaaSInfrastructure as a Service (IaaS)
OpenStack Compute (Nova) is a cloud computing fabric controller, which is the main part of an IaaS system.
Typically IaaS involves the use of a cloud orchestration technology like Open Stack, Apache Cloudstack or Open Nebula.

HP Cloud

The RADOS Gateway also exposes the object store as a RESTful interface which can present as both native Amazon S3 and OpenStack Swift APIs.

Ubuntu version history

Ubuntu 10.04 LTS14.04 LTS13.04
In 2011, developers of the Ubuntu Linux distribution adopted OpenStack with an unsupported technology preview of the OpenStack "Bexar" release for Ubuntu 11.04 "Natty Narwhal".
The OpenStack cloud computing platform was added in this release.

Software-defined networking

Administrators can use software-defined networking (SDN) technologies like OpenFlow to support high levels of multi-tenancy and massive scale.
At the 2014 Interop and Tech Field Day, software-defined networking was demonstrated by Avaya using shortest path bridging (IEEE 802.1aq) and OpenStack as an automated campus, extending automation from the data center to the end device, removing manual provisioning from service delivery.
