12. Productivity Myths You have to give up control for more simplicity Not always… Less code = more productivity Productivity is measured by units of features being delivered (not lines of code) Opinionated architecture (Rails/Grails) is extremely productive ® Copyright 2011 Gigaspaces Ltd. All Rights Reserved 12 “..developing on GAE introduced such a design complexity that working around it pushes us 5 months behind schedule.” Carlos Ble's post Goodbye Google App Engine

13. So Who’s Better? Google/Heroku Top-down sandbox approach Highly opinionated Designed for extreme simplicity at expense of user control Amazon Bottom-up approach Designed for extreme simplicity with a significantly higher degree of control ® Copyright 2011 Gigaspaces Ltd.

15. PaaS on OpenStack – Aim Higher Anyone should be able to: Build their own PaaS in a snap Run on any cloud (public/private) Gain multi-tenancy, elasticity… Without code changes. Provide a significantly higher degree of control without substantial complexity Language choice OS Middleware stack Should come pre-integrated with popular stack Spring,Tomcat, DevOps, NoSQL, Hadoop… Designed to run the most demanding mission-critical apps ® Copyright 2011 Gigaspaces Ltd.

35. Summary Curving out complexity, opinionated architecture, relying on someone else’s stack is only one way to achieve productivity at the expense of control With OpenStack we can aim higher and make the application infrastructure simpler and better suited for the cloud in the first place ® Copyright 2011 Gigaspaces Ltd.
