Cloud Recovery

In general, disaster recovery is a plan for duplicating computer operations after a catastrophe occurs, such as fire or earthquake. It includes routine off-site backup as well as a procedure for activating vital information systems in a new location. One method of off-site backup is often referred to as backing up to the cloud.

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the “cloud” that supports them.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.

Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, comprises of hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.

Cloud architecture extends to the client, where web browsers and/or software applications access cloud applications. Cloud storage architecture is loosely coupled, where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or users.

A cloud computing provider or cloud computing service provider owns and operates live cloud computing systems to deliver service to third parties. A user is a consumer of cloud computing. With disaster recovery, you can recover from the cloud at a low cost though time to recover (RTO) depends on the architecture.
