Unified Programming Model

The SOA Journey Point-to-Point Message Based

Microsoft & SOA Provides the best integrated, cost effective, interoperable, and scalable SOA Platform Windows Servers, BizTalk Server, SQL Server,.NET Framework, Visual Studio.NET, CSF,… Connected Systems Division BizTalk Server Business Activity Monitoring Windows Communication Foundation WS-* compliant Windows Workflow Foundation How do we communicate with each other?

What Does WCF offer to the Enterprise Where are we? Do we have unified MS offering to compliment MS Server technology? Can WCF be the answer? MQ = WCF EAI Message Broker = Biztalk V.Next Mapping done by Biztalk Mapper Unified API to invoke ALL windows server technology Use Adapters (i.e. SAP, Oracle) for non MS products

The Challenge We are putting basic instrumentation, control mechanisms, diagnostics “in the box” with WCF Much of what you’ve had to code in the past is now done for you in the framework You’ll get manageable Web Services with WCF even if you don’t code for manageability You can raise the bar for manageability! Now that you don’t need to write timer code to determine latency, throughput, error rates… What can you do with that same investment?

What Does WCF Offer? Configuration driven Implementing logging and tracing Using performance counters WCF out of the box Create custom counters WMI objects. Out of the box Creating specified WMI objects Leveraging new.NET 3.0 utilities Configuration Editor Trace Viewer

Coding a WCF Service - The Basics Service Contract Contracts are interfaces Service Implements the contract to provide business logic for the server endpoint Service instancing Host Hosts the service to make it available to clients Self-hosted services Client Implements a UI to consume the service for the client endpoint
