Windows Server AppFabric does this What’s the Problem? Who should create application infrastructure? Possible solutions: Application developers Software vendors, e.g., Microsoft Windows Server AppFabric does this

What Is Windows Server AppFabric? It’s application infrastructure technology with two parts: AppFabric Caching Services Provides a distributed cache AppFabric Hosting Services Provides hosting and management services for applications built using Windows Communication Foundation (WCF) 4 Especially WCF applications built using Windows Workflow Foundation (WF) 4 An application can use these two parts separately or together

AppFabric Caching Services Tech Ed North America 2010 5/27/2018 12:46 PM AppFabric Caching Services © 2010 Microsoft Corporation. All rights reserved.

AppFabric Caching Services does this (mostly) What’s the Problem? How can I increase the speed and scalability of applications that access data? Possible solutions: Buy a bigger database machine Cache repeatedly accessed data on the same computer as the application logic Cache repeatedly accessed data on one or more shared computers AppFabric Caching Services does this (mostly)

Illustrating AppFabric Caching Cache Cluster AppFabric Caching Services Cache Server Cached Data Cache Client AppFabric Caching Services Cache Server Cached Data Local Cache Cached Data AppFabric Caching Services Cache Server Cached Data

How Data Gets In and Out of the Cache All data in the cache is explicitly put there by a cache client AppFabric Caching Services provides an API Your code can be written to use the cache The ASP.NET Session object can store its state in AppFabric Caching Services via a config option Your code can use the cache with no changes The cache can delete data: After a configurable timeout To make room for other data that’s accessed more often

Using AppFabric Caching Services with ASP.NET Scenario Web Server Cache Cluster 1) Provide data that’s stored in the Session object ASP.NET Pages 2) Store Session object data in cache AppFabric Caching Services Web Server ASP.NET Pages 4) Retrieve Session object data from cache 3) Make request that relies on data stored in the Session object Web Server ASP.NET Pages Application Database

What Kinds of Data Can Be Cached? Changing data that’s accessed by a single client Such as the information in an ASP.NET Session object Unchanging data that’s accessed by multiple clients Such as catalog information for an online retailer Changing data that’s accessed by multiple clients AppFabric Caching Services provides both optimistic and pessimistic (lock-based) concurrency control

Using AppFabric Caching Services for High Availability Scenario Cache Cluster Cache Server AppFabric Caching Services 3) Return value of data item X from secondary copy Cache Client Primary copies X Secondary copies X Cached Data Cache Server 2) Access data item X AppFabric Caching Services 1) Cache server holding primary copy of data item X fails or is shut down Cached Data

AppFabric Hosting Services adds to this What’s the Problem? Where should I run WCF services? Especially those built using WF? And how can I manage them? Possible solutions: Build my own host process Use the IIS/WAS hosting and management infrastructure AppFabric Hosting Services adds to this

Illustrating WCF WCF provides a common foundation for building and consuming services RESTful, SOAP, and others Endpoint Visual Studio WCF Service Client HTTP, SOAP, Others

Illustrating WF Visual Studio Workflow WF Workflow Designer Activities Other Activities Workflow Activities Base Activity Library WF Runtime

Why Use WF? (1) It allows creating scalable applications With built-in state management (perhaps over a long period of time) It allows creating application logic in a unified way Rather than spreading it across, say, multiple ASP.NET pages It provides built-in tracking of an application’s execution Such as recording when each activity is entered and exited

Why Use WF? (2) It can make programming parallel work easier With the Base Activity Library’s Parallel activity It can help create re-usable logic With custom activities It allows defining logic graphically With the Workflow Designer

Illustrating a Workflow Service A WCF service whose logic is implemented as a WF workflow is called a workflow service WF Runtime WCF Client

Hosting a Workflow Service WF WCF IIS Worker Process IIS Manager AppFabric Extensions Client Persistence Store Monitoring Database

Scaling a Workflow Service with AppFabric Hosting Services Scenario Web Server 1) Make first request to application ASP.NET Pages 2) Invoke workflow service 3) Persist workflow state after handling request Web Server ASP.NET Pages Persistence Store AppFabric Hosting Services 4) Make second request to application 6) Load workflow state and handle request Web Server ASP.NET Pages 5) Invoke workflow service

AppFabric Hosting Services and BizTalk Server Scenario Workflow Service Client BizTalk Server Adapters Orchestration ERP Application

AppFabric Hosting Services or BizTalk Server? Making the choice AppFabric Hosting Services and BizTalk Server have some technical similarities, such as: Both use workflow/orchestration Both can use WCF-based communication Deciding which one to use is usually easy: AppFabric Hosting Services is for applications BizTalk Server is for integration Building your own integration server using AppFabric Hosting Services probably won’t make financial sense

AppFabric Hosting Services and Service Bus Scenario 3) Discover Service Bus endpoint 2) Expose Service Bus endpoint 4) Invoke operation on Service Bus endpoint 5) Invoke operation on service endpoint 1) Register service endpoint Organization Y Client Organization X AppFabric Hosting Services Service WCF

A Tale of Two AppFabrics Windows Azure AppFabric provides: Service Bus Access Control Windows Server AppFabric provides: Caching Services Hosting Services Microsoft tells us that Caching and Hosting will both appear in Windows Azure AppFabric sometime fairly soon

Creating Composite Applications Scenario Purchasing Application Business Partner Service Bus AppFabric Hosting Services Workflow Service CRM Application Client BizTalk Server ERP Application

Using Hosting and Caching Together Scenario AppFabric Caching Services Cache Cluster Cache requests spread across cache servers Web Server User requests spread across Web servers AppFabric Hosting Services Service requests spread across middle-tier servers

Conclusions Windows Server AppFabric provides supporting services for applications Caching services for ASP.NET applications and others Hosting services for WCF services, especially workflow services The goal is to let application developers spend more time building application logic And less building infrastructure
