Spring your apps into the cloud with a PaaS
summary
Live demo builds and deploys a Spring web app to OpenShift PaaS using Git and server-side Maven, adds Tomcat 7 and MongoDB 2.4 cartridges, imports 30 JSON documents, creates a 2D geospatial index, and serves a Leaflet/OpenStreetMap frontend. Deployments are tracked and rolled back by hash, port forwarding enables Eclipse debugging, Watchman restarts OOM processes, and auto-scaling kicks in (auto-scaling at 16 concurrent requests) to spin 512 MB gears up to five nodes under BlazeMeter load tests (BlazeMeter JMeter in the cloud).
