Orchestrating resources in a multilayer computing environment by sending an orchestration message between layers

Software that generates a message containing program instructions for multiple layers in a multi-layer environment, by performing the following operations: (i) receiving an operation to perform across a multilayer computing environment; (ii) generating a message for performing the operation across the multilayer computing environment, wherein the message includes a plurality of layer portions, wherein each layer portion corresponds to a respective layer in the multilayer computing environment and includes computer program instructions for performing a set of sub-operation(s) of the operation; and (iii) orchestrating, by one or more processors, performance of the operation by sending the message between layers in the multilayer computing environment, wherein when the message is located at a respective layer, the layer performs its respective set of sub-operation(s) according to the computer program instructions included in the layer's respectively corresponding layer portion of the message.
