The document discusses how a company called ACME developed and tested a new application on Oracle Cloud. It describes ACME's need to upgrade an existing on-premise application within 2 months. Using Oracle Java Cloud Service and Developer Cloud Service, ACME was able to quickly set up development and test environments in the cloud. Developers could then collaborate on tasks, commit code changes, and have the code built and deployed to the test environment for automated testing. When ready, the application domain could also be migrated from on-premise to Java Cloud Service.
