3. Reasons to scale out Increases Reliability Increases Performance Provides Elastic Scalability

4. So why isn’t everyone doing it?

5. Scale Out Challenges Design Considerations Management Complexities Maintenance Challenges

6. Components of a scaled out architecture Load Balancing Network Load Balancing Queued Processing Workflow Distribution Distributed Caching

7. Increase Reliability & PerformanceLoad Balancing Use load balancing to spread work across multiple machines Building out instead of building up uses lower cost resources Elastic scaling for extra capacity Prevent single point of failure

8. Network Load Balancing NLB: Network Load Balancer ARR: Application Request Routing F5 BigIP Local Traffic Manager Increase Reliability & PerformanceLoad Balancing Options

9. Workflow Distribution Windows Server AppFabric Increase Reliability & PerformanceLoad Balancing Options

10. Increase Reliability & PerformanceLoad Balancing Options Queued Processing Pick a queue: MSMQ, SQL Service Broker, SQL Table, etc. Process it with a multi-threaded Always-On Services Queue Workers Enqueue

11. Effects of Queued Processing

12. Increase Reliability & PerformanceCaching Using caching to decrease load on centralized database resources Load balanced web servers required shared session

13. Increase Reliability & PerformanceDistribute Your Cache A Distributed Cache has these benefits: In-Memory for Performance Replicated for Reliability ASP.NET providers for easy integration Doesn’t add a single point of failure Options Windows Server AppFabric Cache (“Velocity”) MemCached

14. Management & MaintenanceChallenges A scaled out infrastructure presents its own set of challenges: How do I provision resources easily? Do I need to manage each machine individually? How do I deploy application updates? How do I automate the manual tasks?

15. The Solution…

16. Management & Maintenance Solutions:Application Platform IIS7+AppFabric: Application Platform Unified application platform: web sites, web services, always-on services Move your Windows Services to IIS7 with AppFabric to improve management & deployment

18. Server-side service

19. MSBuild packaging support

21. Management & MaintenanceSolutions Web Farm Framework 2.0 Centralized farm management Easily provision resources Distribute updates across the farm Ease maintenance with rolling upgrades & automatic load balancer control Extensible: Plug-ins for managing 3rd party load balancers
