23. Windows Azure AppFabric Cache
• A distributed, in-memory cache for apps running in Azure:
– In-memory cache located near your Azure applications
– Based on Windows Server AppFabric Caching
• Benefits:
– Highly scalable with low latency and high throughput
– Can dynamically increase and decrease as needed, without redeploying
or modifying your application
– User doesn’t have to bother with configuration, deployment, or
management of their cache infrastructure
24. Key Capabilities & Benefits
Web Role
• Easily integrates into existing apps Local Cache
– Cache-Aside Model
– One API for Server and Cloud Output
– ASP.NET Session State Provider Sessions
– ASP.NET Page Output Caching Provider Reference
