> Currently Airavata supports single jobs by wrapping it as a single node task within a workflow. This wrapping is justified if workflow is the predominant use of Airavata and single application execution is a rare usage pattern. As Airavata is getting more usage, the simple execution but for large number of invocations and diverse applications is getting more widely used. 
> Providing a first class way of a simple application execution will reduce the overhead in creating and managing workflows. But this takes away all the orchestration capabilities provided by the Workflow Interpreter. This Epic is to discuss a new component to Airavata which provides based job orchestration while persisting the request state to registry so the application management component (GFac) can be stateless and recover the job from a frequently checkpointed state from the registry
