Leveraging Jetstream2's Multi-Region Cloud Infrastructure to Develop and Support a Science Gateway

This paper explores the experience and benefits ofleveraging the multi-region cloud infrastructure of Jetstream2to develop and support science gateways, with a specific focuson the Hawaii Climate Data Portal (HCDP). As climate changeimpacts intensify, access to up-to-date climate information anddata is critical for researchers, decision-makers, and communitiesto facilitate appropriate preparation and response. The HCDP,a web-based portal, provides access to historical and near-real-time gridded monthly and daily climate products for Hawaii,enabling applications such as drought planning and wildfiremanagement. A key challenge for such gateways is ensuring theconsistent acquisition of transient datasets that are only availablefor limited time windows, sometimes less than 24 hours. Thisdocument details how deploying the HCDP’s data acquisitionand processing workflows across multiple Jetstream2 regionsaddresses this challenge, offering improved availability, failovercapabilities, and data backup. We discuss the architecture,benefits, and inherent challenges (such as cost and complexity)associated with this multi-region deployment approach, providingan experiential case study of its implementation for a criticalclimate science gateway.
