Likewise for software, we need middleware…

… all sorts of middleware, in fact

Windows Azure AppFabric

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

Key Capabilities & Benefits

• Easily integrates into existing apps – Cache-Aside Model

– One API for Server and Cloud

– ASP.NET Session State Provider

– ASP.NET Page Output Caching Provider

• Very low latency with Local Cache

• Caches any serializable CLR object – No serialization costs for local caching

• Secured w/ Access Control Service

We have “Topics” in the cloud. Do you?

Bridging on premise messaging with the Cloud

• Messages are pushed to MSMQ

• Broker reads off MSMQ and publishes to SB Queue

• Service Bus Queue Client can reads it off the queue
