2. Agenda Caching 101 Introducing the new Windows Azure Caching (Preview)
Demos

3. Session Takeaways
Use caching to improve your app performance and reduce DB load
New model of caching on Windows Azure is available in Preview now
Faster, cheaper and easier to develop, deploy and manage

4. Basic caching concepts

5. What is Windows Azure Caching?
A distributed, in-memory, flexible cache for all data types that can be used to speed up Windows Azure applications and reduce database load.
Windows Azure
Caching
Basically, caching helps your app become faster.

6. Why do I need caching? Load on server increases with usersLB
Add a load balancer and more web instances
Web tier
Continue to scale out the web and BI tiers
BI tier
DB load starts to increase, DB becomes the bottleneck
Data tier

7. Why do I need caching? Improve application performanceLB

8. What can I cache? Reference Data Activity Data Resource Data
Product catalogs
Employee data
User profiles
Images
Session state
Shopping cart
Game scores and state
Social feeds
Query output results
Airline seating charts
Inventory management system
Game leaderboards
Performance counters
Weather
Stock quotes
Reference Data
Read-heavy, changes infrequently
Activity Data
Read/Write, created and maintained during a user session
Resource Data
Read/Write, common resource accessed by multiple users

11. Listening to you Raising the bar Better quota management
Relax the limits and warn me before I cross them
What if there were no cache quotas at all?
Flexibility, control, isolation
Make the service less of a black box
What if you had control over cache like your app?
Larger caches
Give me caches bigger than 4GB
How about hundreds of GB of cache?
Lower cost
Cache should be cheaper than $45/mo for 128MB
What if you didn’t pay a premium for cache?
No compromises with perf
Hold the bar
How about reducing latency by more than half?

12. Windows Azure Caching – (Preview)
Introducing…
Windows Azure Caching – (Preview)
The new fast, feature-rich and flexible cache on Azure

13. Windows Azure Caching (Preview) is a new model of caching on Windows Azure where…
Cache is a part of your app
Cache is deployed on regular web and worker roles
Cache lives inside your cloud service
Cache is scaled, managed and monitored just like your app

14. How is the new caching model different?

Cache cluster lives inside your cloud service
Cache is added to a web/worker role
Cache is packaged with your app
Caching server bits are delivered via the SDK

15. Benefits of the new caching model
No cache quotas or throttling
Your application is the only consumer of cache. Use as much cache as your app needs, only limited by physical capacity.
Isolation, Flexibility & Control
Co-located and dedicated topologies allow you maximize your resources. You have as much control over cache as you do over your own application.
Lower cost
Pay no premium for cache. Pay only for the web/worker roles on which cache runs. In co-located, you’ve already paid for the role!

16. Benefits of the new caching model
Easy to scale
Scale cache just like you scale your app. Scale up, scale out, as often as you want. Bigger caches – 100+ GB.
Great development experience
Integrated Visual Studio experience to make it easy to add cache to your app. Full fidelity devfabric experience for debugging your application before deployment.
Support for memcache
Support for the memcache binary and text protocols for easy migration of memcache-based applications to Windows Azure.

17. Benefits of the new caching model
Feature rich
Named Caches
Regions & Tags
High Availability
Local cache with notifications
API symmetry with AppFabric Server
Improved Performance
The bread and butter of caching - latencies that are 4x faster than Windows Azure Shared Caching.

22. Announcement
Support for memcache

23. Support for the memcache protocol
Open and Flexible
Windows Azure Caching (Preview) supports the memcache binary and text protocols and can be used with the dedicated and co-located deployments
Bring your existing memcache-based application to Windows Azure!
Existing .NET, Java, PHP, Node.js applications using memcache can migrate to Windows Azure easily with no changes to the caching code
Better than memcached
Take advantage of features like resiliency, local cache, Visual Studio and portal integration
