US Patent 10990369 Repurposing serverless application copies

A selection is received of a copy of an application backed up from a first FaaS environment for deployment into a second FaaS environment. An application manifest used to backup the application is accessed. The manifest specifies application functions, backend services, and application function mappings. An application function interacts with a backend service in executing the application. An application function mapping includes a condition under which the application function is invoked. The copy of the application is restored into the second FaaS environment. A condition specified in the restored version of the application function mapping is changed. Based on the changed condition, the restored version of the application function is invoked when the restored version of the backend service performs an operation, and the application function of the application corresponding to the restored version of the application function is not invoked.
