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

This paper explores the experience and benefits of
leveraging the multi-region cloud infrastructure of Jetstream2
to develop and support science gateways, with a specific focus
on the Hawaii Climate Data Portal (HCDP). As climate change
impacts intensify, access to up-to-date climate information and
data is critical for researchers, decision-makers, and communities
to 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 wildfire
management. A key challenge for such gateways is ensuring the
consistent acquisition of transient datasets that are only available
for limited time windows, sometimes less than 24 hours. This
document details how deploying the HCDP’s data acquisition
and processing workflows across multiple Jetstream2 regions
addresses this challenge, offering improved availability, failover
capabilities, and data backup. We discuss the architecture,
benefits, and inherent challenges (such as cost and complexity)
associated with this multi-region deployment approach, providing
an experiential case study of its implementation for a critical
climate science gateway.
