Introducing AppFabric
Windows Server AppFabric
Windows Azure AppFabric

What is Windows Server AppFabric?
Extensions to Application Server role on Windows Server Platform
Enhanced hosting, management and caching capabilities
Allows faster, more scalable and more manageable applications and services
In its first release, it comprises of
AppFabric Caching Services (remember Velocity?)
AppFabric Hosting Services (remember Dublin?)

Distributed Caching

AppFabric Cache
Caches any serializable CLR object and provides access through simple cache APIs.
Supports enterprise scale: tens to hundreds of computers.
Configurable to run as a service accessed over the network
Supports dynamic scaling-out by adding new nodes
Backup copy provides high availability
Automatic load balancing

AppFabric Cache Contd.
Integration with administration and monitoring tools such as PowerShell, Event Tracing for Windows, System Center, etc.
Provides seamless integration with ASP.NET to be able to cache session data in without having to write it to source databases. It can also be used as a cache for application data to be able to cache application data across the entire Web farm.
Follows the cache-aside architecture (also known as Explicit Caching) for V1. That is, you must decide explicitly which objects to put/remove in your applications and the cache does not synchronize with any source database automatically.
Types of data: Reference Data, Activity Data and Resource Data...

Demo
Simple Caching Client!

Asp.Net Caching Scenario

Demo
Asp.Net Caching Provider!

Setting up Asp.Net Caching Provider
<sessionStatemode="Custom"customProvider="SessionStoreProvider">
<providers>
<addname="SessionStoreProvider"type="Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider, Microsoft.ApplicationServer.Caching.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"cacheName=“YourCacheName"/>
</providers>
</sessionState>

High Availability Scenario

Hosting capabilities
Windows Server AppFabric

Hosting and Management
Extension to IIS7 using WAS
Hosting and Management of WCF and WF
Load balancing 100s of nodes
Increased availability
Easy to setup base configuration (replicated via msdeploy.exe/xcopy/powershell)
Event Collection via ETW for Windows
Lifecycle management of durable workflows
