RUNTIME MANAGEMENT OF APPLICATION COMPONENTS

Techniques are described for runtime checking of function metadata prior to execution of a function in an environment. An application may include any appropriate number of components at one or more levels in a hierarchical arrangement, and each component may be packaged with metadata that describes the component. A function, or any component, may be packaged with metadata that includes term(s) governing the usage of the function. The term(s) may be checked, at runtime, during execution of the application to determine whether the function is to be executed. A function may also be hashed at runtime for verification of function version. Function(s) may be individually and independently executed as containerized nano functions within the environment.
