  1. SESSION CODE: ASI201 Intro to Workflow Servicesand Windows Server AppFabric Matt Milner Instructor Pluralsight

  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

  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

  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 Lock Retry Durable Timer 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 Id=456 Id=789 Id=123 WMS WMS WMS State Id=789 Id=456 Id=123 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
