AMQP Messaging protocol support for Airavata WS-Messenger
---------------------------------------------------------
Key: AIRAVATA-339
URL: https://issues.apache.org/jira/browse/AIRAVATA-339
Project: Airavata
Issue Type: New Feature
Reporter: Suresh Marru
Airavata WS-Messenger is a Web Services-based Messaging System for
Service-Oriented Computing and is an implementation of WS-Notification and
WS-Eventing specifications. The message format can be automatically converted
between the two specifications.
With an increasing adoption of AMQP, Airavata community has interest to support
this protocol. The subscription request type can be AMQP or Ws-Notification or
WS-Eventing for a listener determines the message format that the notification
consumer will receive. Currently, if WS-Notification subscription request is
received by the broker, it will send WS-Notification messages to the listener.
Similarly, if WS-Eventing subscription is received by the broker, the broker
will produce WS-Eventing messages for that listener. The publisher can publish
messages in either format. The consumers will receive messages in the format
they subscribed irrespective of the format the message is published. We want to
extend this functionality to interoperate with AMQP similarly.
There is extensive literature about Airavata WS Messenger including 4 research
papers. The Airavata community will provide guidance and assistance with the
project.
User community & Impact of the software: Airavata is primarily targeted to
build science gateways using computational resources from various disciplines.
The initial targeted set of gateways include projects supporting research and
education in chemistry, life sciences, biophysics, environmental sciences,
geosciences astronomy and nuclear physics. The goal of airavata is to enhance
productivity of these gateways to utilize cyberinfrastructure of resources
(e.g., local lab resources, the Extreme Science and Engineering Discovery
Environment (XSEDE), the Open Science Grid (OSG), University Clusters, Academic
and Commercial Computational Clouds like FutureGrid & Amazon EC2). By using
open community based software components and services like Airavata, gateways
will be able to focus on providing additional scientific capabilities and to
expanding the number of supported users. The capabilities of these gateways
will offer clear benefits to society.
