Systems and methods of executing an application in an application specific runtime environment are disclosed. The application specific runtime environment is defined by an application environment specification to include a minimal or reduced set of software resources required for execution of the application. The application environment is generated by determining software resource dependencies and is used to provision the application specific runtime environment in real-time in response to a request to execute the application. Use of the application specific runtime environment allows the application to be executed using fewer computing resources, e.g., memory.
