The Apache Airavata Application Programming Interface: Overview and Evaluation with the UltraScan Science Gateway

Abstract

We present an overview of the Apache Airavata Application Programming Interface (API), describe the design choices and implementation details, and describe how API methods map to the UltraScan Science Gateway use case. The Airavata API is designed to standardize access to Airavata services that provide gateways with scientific application metadata and execution management. The API also represents an important milestone in the development of Science Gateway Platform as a Service (SciGaP), a hosted, multi-tenanted gateway service based on open source Airavata software. The UltraScan gateway is a production XSEDE gateway that has been using Airavata services for over three years through customized interfaces and represents a stringent test of the API design and implementation.
