Representational state transfer (REST) or RESTful web services allow you to provide interoperability between computer systems on the Internet. Using the REST-compliant web services you can request systems to access and manipulate textual representations of web resources using a uniform and predefined set of stateless operations. Cisco has now built capabilities of using RESTful APIs to configure the UCS C-series servers using the Redfish™ technology.
Redfish™ is an open industry standard specification and schema that specifies a RESTful interface and utilizes JSON and OData to help customers integrate solutions within their existing tool chains. It utilizes a range of scalable IT technologies that are widely used, and by using these accepted technologies, it makes the use of Redfish™ easier. Redfish™ is sponsored and controlled by the Distributed Management Task Force, Inc. (DMTF), a peer-review standards body recognized throughout the industry.
