OpenStack Cloud

OpenStack is a community of open source developers, participating organizations and users who are building and running the open source cloud operating system.

“OpenStack is an Infrastructure as a service which is known as a Cloud Operating System, that takes resources such as compute, storage, network, virtualization technologies and controls those resources at a data center level”

“OpenStack’s basic requirement: “Cloud must be simple to implement and massively scalable”

OpenStack Project

• OpenStack Compute (Nova): Provision OpenStack Compute: provision and manage large networks of virtual machines

• OpenStack Object Store (Swift): Create petabytes of reliable storage using standard servers

• OpenStack Image Service (Glance): Catalog and manage large libraries of server images

• OpenStack Quantum Service: provide Network as a service to compute.

• Other components: Dashboard, Authentication(Keystone), CLI...

OpenStack Releases

Why OpenStack

• Control and Flexibility. Open source platform means you’re never locked to a proprietary vendor, and modular design can integrate with legacy or third-party technologies to meet  your business needs.

• Industry Standard.  More than 60 leading companies from over a dozen countries are participating in OpenStack, including Cisco, Citrix, Dell, Intel and Microsoft, and new OpenStack clouds are coming online across the globe.

• Proven Software.  Run the same software that today powers some of the largest public and private clouds in the world.

• Compatible and Connected. Compatibility with public OpenStack clouds means enterprises are prepared for the future—making it easy to migrate data and applications to public clouds when conditions are right—based on security policies, economics, and other key business criteria.

stack.sh: shell scripted source install

quickest path to running code that is accessible to change

see everything that gets installed and configured

nova services, glance, keystone, swift, dashboard and quantum

runs all the services in named screen sessions
