Abstract

In certain embodiments, a Service Deployment Infrastructure (SDI) request engine is disclosed. The SDI request engine performs the tracking, management and provisioning of services subscribed to by customers of the cloud infrastructure system. The SDI request engine is deployed to process large volumes of provisioning requests and deliver time critical applications for customers. The SDI request engine translates each request into a list of tasks of various sizes based on the requirement and configuration of the request. In some embodiments, the SDI request engine imposes control and management on both request and task levels in order to execute, rollback, retry or fail a task automatically and accurately.
