A solution descriptor comprises a set of component workload units, a workload unit describing a deployable application component with application binary, configuration parameters and dependency declarations. An environment descriptor specifies a set of target platforms and plugins in an execution environment. A deployer interprets the solution descriptor and the environment descriptor, and generates a list of tuples comprising compatible workload-plugin-platform combinations. The deployer determines an execution order for the list of tuples, and invokes the plugins in the list of tuples in the execution order, wherein each of the plugins executes a corresponding compatible workload on a corresponding compatible target platform specified in the list of tuples. |

1. A method of specifying, deploying and managing composite applications, comprising:
receiving a solution descriptor comprising a set of component workload units, a component workload unit describing a deployable application component with application binary, configuration parameters and dependency declarations; receiving an environment descriptor specifying a set of target platforms and plugins available in an execution environment; generating, by a processor, based on the solution descriptor and the environment descriptor, a list of tuples comprising compatible workload-plugin-platform combinations; determining, by the processor, an execution order for the list of tuples; and invoking, by the processor, the plugins in the list of tuples in the execution order, each of the plugins executing a corresponding compatible component workload unit on a corresponding compatible target platform specified in the list of tuples, wherein the set of component workload units comprises an instance of a component application type in a set of component application types, and the set of component application types is extensible. |
