…. maybe not so easy, after
all.
But there’s middleware to help
with most of this …
… all sorts of middleware, in fact
Windows Azure AppFabric
Service Bus Access Control Web Services
Workflow
Integration
• How do you linearly scale your application to handle increasing load?
• How do you get better performance and reduced data access
latencies?
• How do you store data mash-ups from multiple data repositories?
• How do you manage ASP.NET session state and page output
caching?
• How do you reduce data-tier pressure without complex partitioning?
• How do you do all this with a predictable cost model?
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
Web Role
• Easily integrates into existing apps

Data
• Very low latency with Local Cache
• Caches any serializable CLR object

Data
– No serialization costs for local caching
• Secured w/ Access Control Service
DB
Cache Capacity
• Available in multiple sizes
– 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB
• Use combination of these sizes or multiple of these
to create your desired cache capacity
• Increase/decrease cache capacity dynamically
– Data preserved when increasing capacity
– Eviction policy followed when decreasing capacity
