Accelerating and maintaining large-scale cloud deployment

A computer system comprising one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:

• program instructions to receive, by a server, a deployment specification, the deployment specification specifying a resource required to implement a requested cloud service;
• program instructions to query, by the server, a resource pool for available resources required by the deployment specifications, the resource pool including a plurality of pre-configured resources for implementing one or more cloud services, each of the plurality of pre-configured resources comprising a virtual machine provisioned from an infrastructure and available for deployment, the virtual machine having installed thereon a set of operating system components and an application;
• program instructions to determine that a first resource within the resource pool matches requirements of the deployment specification;
• program instructions to request first resource metadata associated with the first resource from a database, the first resource metadata including a resource identifier and a resource type of the first resource;
• program instructions to receive the first resource metadata associated with the first resource from the database;
• and
• program instructions to deploy the first resource from the resource pool according to the deployment specification to implement the requested cloud service, deploying the first resource including storing, in a resource registry, the first resource metadata.
