3. Objectives What is PGA? Airavata API overview
Hands on session – using PGA as a science gateway user

4. What is PGA?
PGA is a web application that uses the Airavata API to showcase the features provided by Airavata middleware
Reference implementation
But also a full featured science gateway
PGA we’ll be using for this demo:
