Apache Airavata is software for providing services to manage scientific applications on a wide range of remote computing resources. Airavata can be used by both individual scientists to run scientific workflows as well as communities of scientists through Web browser interfaces. Airavata is composed of several components (Registry, Orchestrator, Application Factory, Workflow Interpreter, Messenger, Credential Store) that implement these capabilities. Airavata community is in the process of rearchitecting Airavata software to serve as the basis of a multi-tenanted, elastically scalable, fault-tolerant Platform as a Service for our community. This introduces several challenges to the current architecture as well as opportunities to leverage and collaborate with other Apache projects. We discuss these experiences and future directions.
