Handling Service Orchestration in the Cloud for GlassFish Presentation in JavaOne, San Francisco, 2011 Speakers: Jagadish Ramu and Sivakumar Thyagarajan, Oracle Corporation. --- Session details ---- Title: Handling Service Orchestration in the Cloud for GlassFish Time: Thursday, 02:00 PM, Hilton San Francisco - Imperial Ballroom B Length: 1 Hour Abstract: A PaaS offering typically facilitates application deployment without the cost and complexity of managing infrastructure, by providing all of the facilities required to build and deliver services. Current Java EE deployment models assume that the deployer provisions the various dependent services of an application. To support PaaS deployment scenarios, GlassFish is working to provide a simplified application provisioning and deployment interface to users, with the runtime handling the discovery of service dependencies, provisioning services, and associating service references with these services. This session details how Java EE containers such as GlassFish can provide such service orchestration capabilities to PaaS application deployers. Track: Enterprise Service Architectures and the Cloud Optional Track: Java EE Web Profile and Platform Technologies Experience Level: Advanced --- Session details ----

10. Cloud Computing
Service Models
• Software as a Service (SaaS)
