OpenStack is a provider of various open source project components that facilitate the establishment of cloud services. It has provided standard APIs that are well suited for multiple implementations. The OpenStack Compute API is a product of the OpenStack Nova project. The API provides a RESTful HTTP service platform for accessing the tremendously scalable and on-demand compute resources using either virtual or physical machines. Its deployment requires access to an OpenStack Compute service provider. The API strictly supports JSON-formatted requests and responses.
