A private cloud is a collection of compute, storage, and network resources for a single tenant that are accessed programmatically via an Application Programming Interface (API) endpoint. A private cloud can be located on-premise or hosted by a third-party provider.
How does this differ from traditional data centers and virtualization? Virtualization is a technology underlying most private cloud implementations. Virtualization enables multiple virtual machines to run on a single physical node. But a private cloud is more than just virtualization. It is a programmatic interface, driven by an API and managed by a cloud controller that enables automated provisioning and management of virtual machines, networking resources, storage, and other infrastructure services.
How Does RightScale Fit In?
Most private clouds are built using a cloud infrastructure technology such as CloudStack or OpenStack. These cloud infrastructure technologies provide the virtual machine, storage, and networking controllers that interact with your hypervisors or bare metal infrastructure. Cloud infrastructure technologies expose these resources as a private cloud.
RightScale interoperates with and orchestrates these private clouds. RightScale gives you the tools to create an elastic data center that is automated and secure. RightScale provides a number of benefits to make your private cloud manageable:
- Link multiple private clouds in your data centers with public clouds.
- Manage and port configurations across your private and public clouds.
- Automate, monitor, and orchestrate your infrastructure resources for scalability, availability, and business continuity.
- Govern your private cloud with role-based access controls, federated identity, auditing, and reporting.
- Abstract and interoperate across private cloud technologies such as CloudStack, Eucalyptus, and OpenStack.
Supported Private Cloud Technologies and Vendors
RightScale supports leading cloud infrastructure technologies such as CloudStack and OpenStack. Each of these technologies, in turn, supports a range of hypervisors. RightScale provides support for ESX, KVM, and XenServer. In addition, RightScale supports hosted private cloud offerings built from these technologies and offered by Datapipe and SoftLayer.
