AppFabric Applications
Windows Azure AppFabric Applications is a Community Technology Preview supporting the composition of services into an application in a manner that simplifies the development and deployment of interacting services.

What you get in CTP 1
AppFabric Developer Tools
Application composition
Package creation
AppFabric Application Manager
Deployment
Monitoring
AppFabric Container
Runtime environment

Service Composition
Services
Properties
Endpoints
Service references
Link endpoints
Container Topology
Scalability (instance count)
Monitoring (trace level)

Modeled Properties
Referenced services include the following properties:
Service-specific definition
ProvisionAction
UnprovisionAction
E.g. SQL Azure ProvisionAction specifies a DACPAC that can provision a SQL Azure database

Referenced (External) Services
The following external services are supported:
Service Bus Queue
Service Bus Topic
Service Bus Subscription
Windows Azure AppFabric Caching
SQL Azure
Windows Azure Blob Service
Windows Azure Table Service
Use MEF to add other services (e.g. Bing Maps)

Service Groups
AppFabric Applications
AppFabric Container (stateless)
Stateful AppFabric Container
Web Container
Each service group deployed to a container
Horizontal scalability at the container level
No vertical scalability in CTP1

AppFabric Container
Contains the following stateless services
Code
WCF Service
Workflow

Stateful AppFabric Container
Contains the following stateful services:
Task scheduler
WCF Stateful services

Web Container
Contains the following web-based services:
ASP.NET
WCF Domain Service – Web (for Silverlight)
WCF Service - Web

Adding a Service Reference
New file: ServiceReferences.g.cs
Contains a class named ServiceReferences
Contains method pair for each service reference:
public static AppFabricContainer1.StatelessContract1.Service1.IService1 CreateImport1();
Use:
CloudTableClient tableClient = ServiceReferences.CreateCloudTableClient();
tableClient.CreateTableIfNotExist(tableName);

Referenced Service Objects

Development Environment
AppFabric Application storage (SQL Express)
File system (C:AF, C:AFSdk)
Windows Azure compute emulator
ContainerGatewayWorkerRole (1)
ContainerStatefulWorkerRole (2)
ContainerStatelessWorkerRole (2)
WebRole
Windows Azure storage emulator
