The document discusses GSK's Edge Node on Demand (ENOD) capability, which enables rapid prototyping by allowing users to provision pre-configured computing environments on demand. ENOD uses Docker containers to deploy virtual computing environments connected to GSK's Hadoop clusters, allowing users to access data and run queries and Spark jobs without needing local software installations. The demo showcases how ENOD provides user isolation, reusability, seamless migration, and sharing of environments across GSK researchers. Some challenges along the way included optimizing network file system performance and container image sizes.
