OpenStack (http://www.openstack.org) is an open-source cloud computing platform for public and private clouds. The technology consists of a series of interrelated projects delivering various components—including compute resources, a distributed object store, and image management—for a cloud infrastructure solution. RightScale currently supports the OpenStack Juno, Kilo, and Liberty versions.

Here is an overview of the various features available through OpenStack.
Virtual machine instance in the cloud.
The name of the machine image that was used to build the instance. A virtual image (or virtual appliance, in hypervisor terminology) represents a collection of software: generally an operating system and accompanying applications or utilities. Administrators use machine images installed in virtual environments (such as a public or private cloud) to define and run virtual machines on a hypervisor.
Every cloud infrastructure provides compute resources and the ability to provision these resources. The most important characteristics of compute resources are CPU, memory and local storage. They tend to factor most heavily into the decision making process of which compute resource you should use to meet your specific requirements. Each cloud provider has varying resources and levels of granularity that they provide. RightScale uses Instance Types to help normalize the offerings. (Note that your cloud provider may not refer to compute resources by the same name.) Instance Types are coded into the RightScale Dashboard; you cannot just create, delete, and maintain your own Instance Types arbitrarily.
A regional datacenter in the cloud. (Datacenter and zone are synonymous.) A cloud will often have multiple Datacenters which can help when architecting a highly available Deployment.
The name of the instance's Security Group. Security Groups serve as firewalls for instances that restrict ingress (incoming traffic) communication based on protocol type (TCP, UDP, ICMP), IP address, and ports. Each instance that is launched must be assigned a Security Group. Security Groups essentially control who can communicate with instances that have been assigned that Security Group. By default, all ingress (incoming) network traffic to an instance is rejected unless the instance belongs to one or more Security Groups whose rules specifically allow that traffic.
