Paper Abstract:
|
Nowadays, due to the rapid increase in the number of available web services, more and more emphasis is put on their reliability, availability, security, etc. In order to meet such non-functional requirements, a service needs to be designed for reliability by making design decisions on a high, architectural level. Fortunately, web service related standards also include how to provide reliable messaging between services (e.g. in WS-ReliableMessaging and WS-Reliability). Several frameworks (like RAMP, RM4GS) implement the standard to provide a reliability middleware. However, these standards typically offer very low, XML-level mechanisms for specifying the reliability parameters of web services when deploying them to a reliability middleware. For this purpose, we propose a model-driven approach for the deployment of web services to standards-compliant reliable middleware. The actual XML descriptors are generated automatically from platform-independent description of services enriched with reliability attributes by model transformations. |
