DESCRIPTION
Presentation given at Spring One 2013 by Cornelia Davis and Scott Frederick. Covers the different types of Cloud Foundry services, including marketplace services on run.pivotal.io, user defined service instances and Cloud Foundry Service Brokers. Also covers buildpacks, the mechanism for bringing application context to the applications that are deployed to and run within the Cloud Foundry PaaS.TRANSCRIPT

New (V2) Services API• Simplifies things a bunch!• Unidirectional - everything initiated from Cloud Controller• Asynchronous provisioning• From V1 RESTful Services API:
– Replace offerings registration with endpoint that allows the CC to GET the offerings
– Remove orphan management
