PAAS is the preferred approach according to Paul Maritz of Pivotal, who said "PAAS is the new OS" and that "Speed is the new Currency" according to Angel Diaz of IBM. Cloud Foundry is an open source PAAS that is considered the world's most open PAAS, with over 15,000 commits and 700 developers, and is endorsed by Pivotal, IBM, and GE. The presenter demonstrated Cloud Foundry through run.pivotal.io and Pivotal CF and encouraged the audience to learn more through Cloudfoundry.org.
