Apache Airavata Stakeholders

Airavata is a framework which enables a user to build Science Gateways. It is used to compose, manage, execute and monitor distributed applications and workflows on computational resources. These computational resources can range from local resources to computational grids and clouds. Therefore, various users with different backgrounds either contribute or use Airavata in their applications. From the Airavata standpoint, three main users can be identified.

• Research Scientists (Gateway End Users)
• Gateway Developers
• Core Developers

Now let's focus on each user and how they fit into Airavata's big picture.

 

Gateway End Users

Gateway End User is the one who will have a model code to do some scientific application. Sometimes this End User can be a Research Scientist. He/She writes scripts to wrap the applications up and by executing those scripts, they run the scientific workflows in Super Computers. This can be called a scientific experiment. Now the Scientist might have a requirement to call multiple of these applications together and compose a workflow. That's where the Gateway Developer comes into the picture.

 

Gateway Developers

The Research Scientist is the one who comes up with requirement of bundling scienitific applications together and composing as a workflow.
The job of the Gateway Developer is to use Airavata and wrap the above mentioned model code and scripts together. Then, scientific workflows are created out these.
Above diagram depicts how Gateway Developer fits into the picture.

 

Core Developers

Core Deveoper is the one who develops and contributes to Airavata framework codebase. The Gateway Developers use the software developed by the Core Developers to create science gateways.
