Corporation 2012 What Do Developers Care About? •  Common development tasks include: •  All tasks should be as painless as possible, with special emphasis on the more frequent ones. If the time taken to accomplish these tasks is an impediment to the development, the cost of the fidelity of the test server runtime is challenged •  These kind of capabilities reflect on the Application Server runtime as well as the tools Hourly Daily Weekly Monthly Frequency •  Modify file within an application •  Debug a problem in an application •  Restart/redeploy application •  Restart server •  Share code with team •  Change app structure (add/remove a module/bundle) •  Make config change •  Share config change with team •  Reproduce problem from another environment •  Upgrade to new service release •  Create application •  Install server fastest faster fast Time to complete 6

Corporation 2012 WAS v8.5: Introduces the Lightweight “Liberty” Profile – For Web, OSGi and Mobile Apps Dynamic Server Profile Not static like Web Profile – determines by app at a fine- grained level Developer First Focus Simplified, shareable server config (like a dev. artifact). One XML file or several to simplify sharing & reuse of config Lightweight runtime Small memory footprint: (46MB for TradeLite) Integration with ND Job Mgr Optionally manage server lifecycle through ND Job Mgr Fidelity to full profile WAS Same reliable containers & QOS (easy migration from dev to ops) Dynamic Runtime Adding features & updating configs does not require server restart A highly composable, dynamic Server profile Popular Platforms Adds MAC OS for development Incredibly fast: start times: < 5 secs Small Download: < 50MB WAS v8.5 Liberty Profile Unzip Install & Deploy IM or unzip to install. Unzip deploy of server + app + config Integrated Tooling Powerful tools. Simple Eclipse feature 7

Corporation 2012 No Hurdles to Install •  Tools and runtime are free for development. No time limit •  Eclipse feature install for tools; 40MB zip download for server profile. –  Installation Manager also supported à same installed result. •  2 minutes from “Nothing” to “Done”: •  Install WAS Developer Tools for Eclipse Feature •  •  Use the Tools to download the WAS Liberty Profile or download 40MB zip from WASdev.net www.wasdev.net 8

Corporation 2012 Simplified Server Configuration •  Simplest case: One XML file for all server config •  Editable within the workspace •  Exportable, shareable, versionable No need for Admin Console, wsadmin, or extended EARs ws-security.xml server.xml etc. resources.xml X 9
