US Patent 10013275 Executing code referenced from a microservice registry

Methods and systems for executing code referenced from a microservice registry are disclosed. For example, a microservice registry is stored in a memory. The microservice registry includes references to a plurality of microservices including a first microservice. An isolated guest executing on one or more processors receives a request to execute an executable code and determines that the executable code is unavailable in the first isolated guest. The isolated guest determines that, based on the microservice registry, the first microservice executes the executable code. The isolated guest forwards the first request to the first microservice and receives a result of the request from the first micro service.
