2. Overview Declarative programming with WF4
Creating declarative workflow services
Understanding Windows Server AppFabric
Deploying and configuring services in Windows Server AppFabric
Managing services with Windows Server AppFabric

3. What is Windows Workflow Foundation?
A framework for declarative programming
Tools for creating program definitions
A runtime for executing program logic

4. Programming frameworks
Declarative programming
Models are the code
Runtime handles execution
Managed languages
Abstract management of memory, objects, etc.
Object oriented languages
Simplified programming constructs
Work with objects just like the real world
C style languages
Move away from machine language to human language
Assembler
Write code for the machine

5. DEMO: Declarative programming with WF

6. Declarative workflow services
Services (WCF) extend the reach of workflows
WF = declarative service authoring and composition
Write services as workflows
Consume services from workflows

7. Benefits of declarative service authoring
Declarative flow control – parallel / async / compensation
Automatic state management
Tracking / visibility
Ideal for:
Long running, multi-interaction processes (e.g. approvals, applications)
Coordinating multiple interactions (e.g. aggregation, composition)

8. Workflow services in WF 4
Messaging activities
Model communications (e.g. receive, reply, send)
WorkflowServiceHost
Customized WCF host for workflow services
Integrates WCF with WF
Message correlation
Enables long running, multi-exchange messaging

9. Content based correlation
1. Start Task123
Application
2. Store Task123
3. Send
Submit Task TaskID= 123
Task789
Task456
Task123
4. Receive
5. Lookup Task123
Task Complete TaskID= 123
6. Task123 Complete
Application State

10. Demo: Declarative workflow services

11. Windows Server AppFabric
Most WCF services are hosted in IIS / WAS
IIS tooling designed for managing web applications
Windows Server AppFabric = service management
Simplified configuration of services and workflows
Operations dashboard
Workflow service management
GUI and PowerShell tools

12. AppFabric hosting architecture
Tools
System Center Operations Manager
IIS Manager
PowerShell
Visual Studio
Runtime services
Workflow management service
Runtime databases
Monitoring
State
.NET Fx
Persistence
Monitoring
Durable
Timer
Lock
Retry
WCF
Tracking WF
Tracking
Routing Service
SQL provider
WCF message logging
IIS / Windows

13. AppFabric deployment and configuration
Simplified configuration and deployment
Default connection strings for persistence and tracking enables xcopy deploy
Many WCF configuration settings surfaced in API and UI
Graphical configuration window
Persistence, diagnostics, WCF throttles, workflow host settings
Easier operations management
Switch tracing levels through API and UI as needed
Enable more detailed tracking of WF events at runtime

14. Demo: Deploying and configuring services
Simplified configuration of services in IIS

15. AppFabric operations dashboard
Health overview provides information about services
Exceptions / completed call count / throttling limits reached
Workflow instances (active / suspended)
Recent history – activations / failures
Access to workflow information
List of persisted workflows
Tracked workflow data and events
Tools are based on tool scope (site / application / service)
Custom queries also possible

16. Workflow instance management
Workflow management service
Windows NT Service running in the background
Monitors persistence store for workflows with work to be done
Ready to run, expired timers, abandoned instances
IIS tooling enables manual service management
Find suspended instance easily
Suspend, resume, or terminate instances

17. Instance recovery State WMS WMS WMS Heartbeats Id=456 Id=789 Id=123

18. PowerShell support
PowerShell is THE modern scripting environment on Windows
Most commands and data available as PowerShell cmdlets
Get and set configuration settings
Enable application messaging
Instance management – resume, suspend, terminate
Combine with other web modules
Web Administration PowerShell module for managing IIS
MSDeploy – synch or deploy local or remote services

19. Demo: Managing services
Operational management of services

20. Summary
WF provides tools for writing declarative programs and services
AppFabric gives you the tools to configure and manage services
Use IIS Manager or PowerShell
Provides additional services beyond .NET Framework
Scalable, manageable solution for hosting services on Windows
