Rolling restoration of enterprise business services following service disruption

摘要

Techniques are disclosed for restoring application services in a computer network following a service disruption. A faster service restoration (FSR) engine identifies one or more servers hosting a service. The service is associated with dependencies between the service and another one of the services. The FSR engine determines successive phases for restoring the application based on the dependencies. Each phase includes one or more clusters of servers, where each server in the cluster executes an instance one of the services. The FSR engine restores the application by each successive phase. In each phase, the restoration maintains a minimum availability of the instances of the services executed in each cluster.
