What is Composite Application service? What are the features included in it?
The Composite Application service is a multi-tenant, managed service which consumes the .NET based Composition Model definition and automates the deployment and management of the end to end application – eliminating manual steps needed by both developers and ITPros today. It also directly executes application components to provide a high-performance runtime optimized for cloud-scale services and mid-tier components (automatically delivering scale out, availability, multi-tenancy and sandboxing of your application components). It also delivers a complete hosting environment for web services built using Windows Communication Foundation (either natively developed or using WCF Data Services and WCF RIA Services) and workflows built using Windows Workflow Foundation.
