  2. This Session • The Cloud, Multi-Tenancy, and the Middle Tier • Why do we need a new middle tier? • What are the required capabilities? • Windows Azure and Server AppFabric • What’s in it? • When can I use it?

  3. Server Apps are Easy, Aren’t They?

  4. Browser Browser Web Server(ASP.NET, PHP, Ruby, …) Web Server(ASP.NET, PHP, Ruby, …) Sessions Sessions DB(SQL Server, MySQL, NoSQL) DB(SQL Server, MySQL, NoSQL)

  6. … add “The Cloud” …

  7. ‘Box’ ISV Business is about R&D Cost Customer Upfront Cost ISV Software License ISV Recurring Cost Customer Recurring Cost $ $ ISV Maintenance Fees Margin Infrastructure Investment (Servers, Switches, Disks, Racks, Server Software, Power Supply, Cooling, …) Per Customer R&D Cost T Income Scales With # of CustomersMargin Widens as R&D Cost is Distributed Box

  8. ‘Cloud’ ISV Business is about Ops Cost • Keys to lower ops cost • Deployment Automation • Self-Healing Architecture • Auto-Scale • High Density • Multi-Tenancy Customer Upfront Cost ISV Software License ISV Recurring Cost Customer Recurring Cost $ $ Service Operation Fee Margin Infrastructure Investment (Servers, Switches, Disks, Racks, Server Software, Power Supply, Cooling, …) Service Operation Cost Service Operation Cost T Growth Opportunity within Current Customer Base - Incentive to Optimize Cloud

  15. Service Bus Integration AppFabric Access Control Web Services Cache Workflow

  16. Service Bus 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? Web Services Access Control Cache Workflow

  17. Cache Service Commercial Availability End of April 2011* *Scheduled Release Date.

  18. Windows Azure AppFabric Cache • A distributed, in-memory cache for applications running in Windows Azure: • In-memory cache located near your Azure applications • Based on Windows Server AppFabricCaching • 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 Cache

  19. Key Capabilities & Benefits Web Role • 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 Local Cache Output Cache Sessions Reference Data Activity Data Resource Data DB

  20. 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 Cache

  21. Apps Browser AuthN/Z Web Server(ASP.NET, PHP, Ruby, …) Sessions Reference Data AuthN/Z Services(WCF, WF, …) Aggregate Data Sessions Reference Data DB(SQL Server, MySQL, NoSQL) LOB Systems

  22. Service Bus Integration • How do you achieve load-decoupling between subsystems? • How do you balance work across scale-out workers? • How do you distribute events to dynamic subscribers? • How do you transfer messages reliably and transactionally? • How do you reach into on-premise systems across firewalls? • How do you organize and discover service endpoints? Web Services Access Control Cache Workflow

  23. Service Bus Commercially Available since January 2010 Brand-New Community Technology Preview Coming May 2011

  24. Service Bus Windows Azure AppFabric Service Bus • Interconnect services across networks • Naming and Discovery • Connectivity w/ NAT and Firewall Traversal • Access Control Integrated Authorization • Cloud-Based Message-Oriented Middleware • Next Generation Message Queue Technology • Rich Publish/Subscribe with Filtering • Transaction Integration

  25. New: Queues Queue/Topic • Durable, Replicated • Rich Functionality • Grouping • For most decoupled scenarios 100MB Durable Storage 256KB No limit Producer SOAP/TCP TTL Storage Capacity Messages REST/HTTP In-Memory 10 min 2MB 60KB AMQP/TCP Consumer Message Buffer • Volatile, not replicated • Simple REST interface • Light online/offline scenarios

  26. New: Topics Service Bus <Topic>…</Topic > • Multiple independent (durable) subscriptions • Multiple rules per subscription, each with one or more filters. 1 Consumer 2 3 4 6 2 Consumer 4 5 Consumer 6 = 7 Topic <Subscribe> <Rule>…</Rule></Subscribe> 8 Producer
