1. A method comprising: detecting, at a control system comprising a processor, a validation request comprising a request to create an end-to-end validation function to perform end-to-end validation of a service; analyzing, by the processor, a policy to determine components of the end-to-end validation function and a virtual machine that will host the end-to-end validation function, wherein the components comprise a generator function and a receiver function, and wherein the generator function and the receiver function encompass the service; triggering, by the processor, loading of an image to the virtual machine and instantiation of the virtual machine, wherein the image comprises the end-to-end validation function; and validating, by the processor, the service using the end-to-end validation function based upon a test scenario stored in a test library of the end-to-end validation function.
