Introducing .NET Services
Microsoft .NET Service BusNetwork infrastructure to connect applications over the cloud
Microsoft .NET Access Control ServiceClaims based access control in the cloud
Microsoft .NET Workflow ServicesInfrastructure for hosting and managing workflows on the cloud
Microsoft .NET Service Bus
Evolution of Distributed Computing
Emerging standards for distributed computingRPC, SOAP, WS-I, WS-* and SOA
MicrosoftCOM, DCOM, COM+, Web Services, WSE and WCF
From Components to Services and Monikers to Endpoints
COM ProgIDs – Customer.Account
WCF End-Point – mycrm.com/services/customer
There are still some challenges!

Benefits of Claims-based Identity
Your application is no longer responsible forAuthenticating users
Storing user accounts and passwords
Calling enterprise directories
Integration with proprietary authentication & authorization systems
Understanding ACS
Access Control for the Cloud Services
Can act as an issuing authority (under current CTP)
Will decouple authentication systems (Issuing Authority & Identity Provider) and clients (Relying Party)
Can be managed via Web Portal or API (Not under current CTP)
Microsoft .NET Workflow Service
Why Workflow in the Cloud?
Paradigm shift from (loosely coupled) components to (loosely coupled) services
Need for declarative way to define the service invocation path
Bring orchestration capabilities to the cloud services platform
Microsoft .NET Workflow Services
Based on the proven WF engine and framework
Full fidelity design, development and deployment environment
Easy and manageable web based portal for manipulating the workflow
Additional Cloud Activities for cloud-based workflow
Completed hosted and maintained on the cloud
Cloud Workflow Activities
Activity Function
CloudHttpReceive Receive HTTP requests posted to a specific URL for the workflow
instance
CloudHttpSend Invoke HTTP GET or POST operations to a specified URL and get the
response
CloudServiceBusSend Send a message to a specific endpoint on the ServiceBus
CloudXPathRead Reads specified data from an input XML
CloudXPathUpdate Set specified data in an input XML document
CloudDelay Waits for a specified time span
Bringing it All Together
.NET Services provide the key building block services for cloud applications
Service Bus for exposing on-premise services on the cloud
Access Control Service for claims-based, federated security service
Workflow service to orchestrate cloud services
