Self-healing system for distributed services and applications

Abstract:

A self-healing system configured to automatically restore non-responsive or failed applications to a normal operating state. A self-healing system may restart an application after confirming that the application itself has failed--and not an underlying dependency failure. The self-healing system may also evaluate a server hosting an application reported as being non-responsive to determine whether that server has itself failed. If an application is non-responsive or has failed on an otherwise healthy host, and the dependent service use by the application are available, the self-healing system automatically restores the application to a responsive state. To do so, the self-healing system may generate a run list specifying a sequence of scripts invoked to restore the application to the responsive state.
