Computer-based methods and systems are provided for building, provisioning and executing one or more electronic service level agreements (eSLAs) for Web and other computer hosting services, which specify and enforce service contracts for Web and other computer hosting services. In one aspect of the invention, a computer-based eSLA system includes four main components: (1) an eSLA builder; (2) an eSLA provisioner; (3) one or more execution systems; and (4) a system configuration and measurement system. Generally, the eSLA builder component provides the mechanism for defining and pricing the eSLA, checking the validity of the eSLA and a repository for storing the completed eSLAs. The provisioning system is responsible for configuring the run-time system in order to meet one or a set of eSLAs. The execution system is responsible for handling the run-time user requests, e.g., Web servers and load distributors, and a mechanism for enforcing the eSLAs at run-time. The system configuration and measurement system maintains information on the current system configuration, and run-time information on the metrics that are part of the eSLA. |
