This is from my Tech-Ed Africa 2010 talk. For more information see: http://www.sadev.co.za/content/teched-africa-2010-slides-scripts-and-demos-my-talks This session looks at what AppFabric Caching is from start to deep dive.

2. Robert MacLean Technology Specialist BB&D Windows Server AppFabric Caching: What it is & When you should use it?

3. Who am I? Robert MacLean Microsoft ALM MVP Microsoft ALM Ranger Proud Community Lead Information Worker S.A. Architect www.sadev.co.za @rmaclean

4. Overture Level 300 State of play Briefly what is AppFabric? What do we get from AppFabric Caching and how to use it!

5. Advert Time AppFabric: Wed, 11:15pm - WCF Made Easy with .NET 4 and Windows Server AppFabric Other: Wed, 8:30pm - Tales From the field – Best practices and guidance on implementing TFS2010

6. State of play .NET prior to 4 ASP.NET Caching Enterprise Library Caching .NET 4 brings us .NET 4 Caching All are local in-memory caches!

7. .NET 4 Caching Demo

8. What is the issue with these? Limited to memory of current machine Limited to current process Imagine if I need 50Gb of cache? What about load balancing?

9. A rose by any other name… Windows Server AppFabric contains two key components Hosting EndPoint, Windows App Server Extensions, Dublin Caching Velocity Not to be confused with Azure AppFabric

10. N.B. AppFabric Requires .NET 4 on Server Not all applications need .NET 4, depends on features used Standalone download or Web Platform Installer High Availability is only in Windows Server 2008 Enterprise & Data Centre

11. What is AppFabric Cache? An in-memory distributed cache which you can call from any .NET application Optimised for the cache-aside pattern Programming against the cache is explicit Changing the cache doesn’t update the original data store

12. AppFabric Cache Single View Cache Server Single view from code Services Cache Server Data 1 Data 2 Data 3 Data 4 Cache Server Cache Server

13. AppFabric Caching Info Common Configuration Store XML Database Runs as Windows Service Communication Between Nodes WCF net.tcp Self Adjusting

14. AppFabric Server Types Dedicated Cache Server All it does is AppFabric caching – good for lots of memory and great performation Hybrid Cache Server Runs AppFabric caching & other tools. SQL + AppFabric Web + AppFabric Local Cache Server Runs AppFabric per application locally Used in conjunction with hybrid and/or dedicated

15. What can I cache? Anything that can be serialised XML POCO Binary Data

16. Data Cache Planning Reference Data Cities, provinces, product info, etc… Activity Data Session, per user etc.. Resource Data Data with contention We will look at this more later… NB: Plan, plan and plan some more

17. Management All Configuration and Administration is done via PowerShell From the MVP’s: http://mdcadmintool.codeplex.com/

18. AppFabric from IT Pro to Developer Demo

19. Cache Structure Review Server Server Server Named Cache: Default Named Cache: Products Named Cache: Users Region: Male Region: Female Items & Tags

20. Expiration of cache items Put & Add Timeout Notification Polling Default: 300 secs Expiration timeout defaults can be controlled on a cache level

21. Eviction @ Low watermark Expired items removed @ High watermark Items, expired or not, can be removed or allocated to another server Items picked by using LRU Can disable if needed

22. ORM’s Some ORM’s implement second level caching It is possible to change the second level to AppFabric Examples: NHibernate & Entity Framework

23. A Problem with Caching AppFabric Cache Name : Robert Balance: 1500 Write DB Name : Robert Balance: 15 ATM ATM ORM UI ORM UI Name : Robert Balance: 15

24. Solution .GetAndLock .PutAndUnlock .Unlock Supports locking timeout Locked items can survive expiration Unlock can prolong expiration

25. Data Cache Planning Reference Data Cities, provinces, product info, etc… Activity Data Session, per user etc.. Resource Data Data with contention NB: Plan, plan and plan some more Great with defaults Region per user Locking per item

26. Cluster Configuration First node initialises cluster Other nodes join During install you must configure projected size Small: 1 – 5 nodes Medium: 6 – 15 nodes Large: > 15 nodes Performance based on this setting – adding/removing nodes does not effect this

27. Security Domain: Authentication in AD, Authorisation in AppFabric Only authorised servers join clusters Only authorised clients connect to clusters Workgroup Authentication in network share, Authorisation in AppFabric Transport Level Security Signing and Encryption

28. Typical Web Architecture Users Web Servers Load Balancer State State State DB

29. ASP.NET Out of the box caching InProc (Default) StateServer SQLServer All can be enabled by via config change Now AppFabric support also just a config change

35. Summary Windows Server AppFabric Cache is a distributed application cache Caching is important to application scalability Explicit caching API available to .NET 3.5 SP1 and .NET 4.0 ASP.NET Session provider an implicit way to take advantage of the Cache’s capabilities Plan, plan and plan some more
