Research and Engineering Studio on AWS (RES) is an open-source, user-friendly web portal designed to empower researchers and engineers (end-users) with seamless access to cloud storage and compute resources. RES enables research IT administrators to easily create and manage projects, including budgets, software stacks, users, and groups, all within a secure environment. With RES, end-users can run simulations, process, share, and visualize their data, access interactive applications, and leverage other native AWS services and solutions without the need to provision AWS accounts or navigate the AWS Management Console directly. In this demo session, we will explore the architecture of RES, showcase its intuitive user interface, highlight the platform's extensibility, and provide examples of how to integrate RES with other AWS services, such as HPC clusters."
