In this paper, we introduce Apache Airavata, a software framework to compose, manage, execute, and monitor distributed applications and workflows on computational resources ranging from local resources to computational grids and clouds. Airavata builds on general concepts of serviceoriented computing, distributed messaging, and workflow composition and orchestration. This paper discusses the architecture of Airavata and its modules, and illustrates how the software can be used as individualdoi:10.1145/2110486.2110490 dblp:conf/sc/MarruGHTPMSGCGSDPW11 fatcat:aumigogsh5gflc242vkm6fchni

This paper provides an overview of the Apache Airavata software system for science gateways. Gateways use Airavata to manage application and workflow executions on a range of backend resources (grids, computing clouds, and local clusters). Airavata's design goal is to provide component abstractions for major tasks required to provide gateway application management. Components are not directly accessed but are instead exposed through a client Application Programming Interface. This design allowsdoi:10.1109/iwsg.2014.15 dblp:conf/iwsg/PierceMGKSWWHCMST14 fatcat:bmlvgzzdxfcsjppkmrzqvtqhbi

This is particularly important as Airavata evolves to become a scalable, elastic "platform as a service" for science gateways. We illustrate the capabilities of Airavata through the discussion of usage vignettes. As an Apache Software Foundation project, Airavata's open community governance model is as important as its software base. We discuss how this works within Airavata and how it may be applicable to other distributed computing infrastructure and cyberinfrastructure efforts.
The UltraScan data analysis application is a software package that is able to take advantage of computational resources in order to support the interpretation of analytical ultracentrifugation (AUC) experiments. Since 2006, the UltraScan scientific gateway has been used with ordinary Web browsers in TeraGrid by scientists studying the solution properties of biological and synthetic molecules. Unlike other applications, UltraScan is implemented on a gateway architecture and leverages the powerdoi:10.1145/2484762.2484800 dblp:conf/xsede/MemonAGGRLMGJDSR13 fatcat:6tloafhrljdq5a75yqwqrewsji

In this contribution, we will focus on several improvements of the UltraScan scientific gateway that enable a standardized job submission and management to computational resources while retaining its lightweight design in order to not disturb the established workflows of its end-users. This paper further presents a walkthrough of the architectural design including one real installation deployment of UltraScan in Europe. The aim is to provide evidence for the added value of open standards and resulting interoperability enabling not only UltraScan application submissions to resources offered in the US cyber infrastructure Extreme Science and Engineering Discovery Environment (XSEDE), but also submissions to similar infrastructures in Europe and around the world. The use of the Apache Airavata framework for scientific gateways within our approach bears the potential to have an impact on several other scientific gateways too.
