OpenStack Introduction
OpenStack is an open source cloud computing platform that provides common services for building public and private clouds. It was launched in 2010 as a collaboration between Rackspace and NASA to create an open source alternative to existing proprietary cloud platforms. OpenStack provides common services for compute, storage, networking and identity management and is made up of interoperable components that can be used together or independently. The project is overseen by the OpenStack Foundation and has grown significantly in contributors and companies involved since its inception.

History • 2009 – –EC2, Rackspace, Nebula (NASA), Cloud.com, vSphere… • August 2010 – Rackspace and NASA share a vision of an open infrastructure platform: OpenStack. – Compute (nova) contributed by NASA (used to power Nebula). – Storage (swift) contribued by Rackspace (used to power cloudfiles).

Editor's Notes
- #3 Virtualization provided a way to abstract data center resources (Compute, Networking, Storage) from their underlying physical infrastructure. This allowed these resources to be pooled and manipulated in multiple ways to provide consolidation, flexibility, and scale. Data center resources can now be scaled-up or scaled-down, moved from infrastructure to infrastructure, and repurposed as needed to meet the demands of the business.What was missing, however, was automation and orchestration of these virtualized resources.

- #6 A Cloud Computing platform sits above the virtual data center and provides both a control plane over and resource access to the virtualized data center. OpenStack, as a Cloud Computing platform, manages virtualized resources, such as virtual machines exported by a hypervisor, network overlays created by Software-Defined Network devices, and volumes exported by virtual storage arrays. OpenStack takes these data center resources and automates and orchestrates them so they can be accessed on demand and be scaled up and down as needed, turning these resources into consumable services.תשובה לשאלות

- #12 Despite common belief, OpenStack by itself is not a product; it is an organization, owned by an independent, non-profit foundation. The sole purpose of this organization is to provide an umbrella trademark and a governance structure for several open source software projects, licensed under Apache 2.0. In this sense it is very similar to the Apache Foundation.All projects under the OpenStack umbrella are united by a common theme: building a piece of software, meant to deliver some component of an IaaS cloud. All OpenStack projects are split into core, incubated and community. Core projects are those that formally fall under the OpenStack umbrella; i.e., they are subject to OpenStack community governance process and are officially endorsed by the community, with regularly scheduled releases. Incubated projects are those that have been voted to be included into core during one of the upcoming releases. Community projects are those that add some value to the OpenStack ecosystem, but are not governed or officially endorsed by the community. I won’t go into the details of the actual OpenStack projects here; there is already a good overview on the OpenStack website.
