Elastic Compute Cloud Plugin

This is a plug-in for the ETICS Submission Webservice that manages jobs executed on EC2.

Being meant to work with Grid middleware (Metronome, gLite, UNICORE), the ETICS Submission Web Service architecture was designed to leverage their job management functionalities. Though with slight differences, all Grid middlewares supports operation for submitting, getting the status, and canceling a job. Elastic Compute Cloud (EC2) has a different semantic. It provides machines, not environment execution for computational jobs. Though the architecture could have been forced to support this case as well, it was decided, in a SOA fashion, to provide a service on its own that deals with execution of jobs in EC2.

Need drawing here with the ETICS Submission Web Service in front of the EC2 execution service, and possibly one with the gLite so to understand the difference.

EC2 Very Basic Execution Service EC2VBES is a service that executes computational jobs on EC2. It implements a (rather small) subset of the OGF OGSA Basic Execution Service V1.0 specification, that present a specification for a service to which clients can send requests to initiate, monitor, and manage computational activities.
