3. Who am I? Maarten Balliauw Antwerp, Belgium www.realdolmen.com Focus on web ASP.NET, ASP.NET MVC, PHP, Azure, VSTS, … MVP ASP.NET http://blog.maartenballiauw.be http://twitter.com/maartenballiauw

4. Agenda Cloud computing? Windows Azure? Application architecture Getting started Resources Q&A

5. What’s in the cloud? Cloud Computing

6. What is Cloud Computing ? What is cloud computing ? Offering infrastructure, platform and software as a service over the internet to a global market. Move on-premises management of non functional IT assets to a provider. Difference from traditional hostings Sold on demand “pay as you grow” Elastic scalability Service is fully managed by the provider End user centric (IW or developer) Strong focus on integration (cloud-cloud or cloud-on-premises)

7. Definition of cloud (NIST) On-demand self service Standardized access Location independant resource pooling Rapid elasticity Pay per use

8. IAAS, PAAS, SAAS ? infrastructure as a service (hardware) Servers available in the cloud, Managed by cloud vendor platform as a service (developer) Delivery of a OS for custom, cloud enabled apps Support for service hosting and interopability Relational data storage in the cloud software as a service (end users) Exchange online Sharepoint online Dynamics CRM online

9. IT as a Service Private (On-Premise) Infrastructure (as a Service) Platform (as a Service) You manage Applications Applications Applications You manage Runtimes Runtimes Runtimes Security & Integration Security & Integration Security & Integration Managed by vendor You manage Databases Databases Databases Servers Servers Servers Managed by vendor Virtualization Virtualization Virtualization Server HW Server HW Server HW Storage Storage Storage Networking Networking Networking

10. Classic IT Capacity problem. Allocated IT-capacities Load Forecast “Under-supply“ of capacities “Waste“ of capacities Fixed cost of IT-capacities IT CAPACITY Barrier for innovations ActualLoad TIME

11. Capacity in a cloud model Load Forecast Allocated IT capacities No “under-supply“ IT CAPACITY Reduction of “over-supply“ Possible reduction of IT-capacities in case of reduced load Reduction of initial investments ActualLoad TIME

12. What’s in the cloud? Windows Azure

13. The Windows Azure Platform Windows Azure SQL Azure Windows Azure platform AppFabric Developer tools Microsoft Codename “Dallas”

14. Windows Azure Flexible application hosting Lights-out service management Provide code & service model, hit ENTER Storage at massive scale Compute Storage Management

15. SQL Azure Relational database as a service Highly available, automatically maintained Extension of the SQL Server Data Platform Business Analytics Reporting Data Sync Database

16. SQL Azure Relational database, provided as a service Highly symmetrical development and tooling experience (use TDS protocol and T-SQL) Highly scaled out, on commodity hardware Built on the SQL Server technology foundation Beyond “hosted database” High availability, DB provisioning, and DB management are provided by the service Pay for what you use

17. Windows Azure AppFabric Secure connections between services Across organizational boundaries Claims-based access control != Windows Server AppFabric (yet?) ServiceBus AccessControl

18. Windows Azure AppFabric - Service Bus Securely connect applications Over the internet Across any network topology Across organizational boundaries Primary application patterns Eventing: Notify applications and/or devices Service Remoting: Securely project on-premises services out to the cloud Tunneling: App-to-app communication with NAT/Firewall traversal

19. Service Bus Overview

20. Windows Azure AppFabric - Access Control Provides outsourcing of claims-based access control for REST web services Key capabilities: Usable from any platform Low friction way to onboard new clients Integrates with AD FS v2 Supports WRAP / SWT Enables simple delegation Used today by Service Bus and “Dallas”

21. Access Control Service

22. Microsoft Codename “Dallas” Content brokerage and discovery platform Available as a CTP at commercial launch Microsoft Codename “Dallas”Information Services

23. Introducing “Dallas” Content Brokerage and Discovery platform Discover, Explore, and Use any type of content (blobs, structured, real-time web services) Tap into an ecosystem of global content providers Process & analyze data Empowers developers of all sizes Built on Windows Azure and SQL Azure

24. Quincy, WA: Complete, approx 500K sq ft San Antonio, TX: Complete, approx 475K sq ft Chicago, IL: Complete, approx 550K sq ft Dublin, Ireland: Opening Summer 09, approx 570K sq ft Des Moines, Iowa: Recently announced land purchase

27. Windows Azure

28. Blob Container Entities Account Table http://<account>.blob.core.windows.net/<container> Messages Windows Azure Storage Concepts http://<account>.table.core.windows.net/<table> Queue http://<account>.queue.core.windows.net/<queue>

29. Blob Storage Store sets of binary data Text files, images, … Highly Available Automatically scales to multiple servers and locations Durable Data is replicated at least 3 times

30. Table Storage Store sets of structured data Not bound to schema! Billions of entities (rows) and TBs of data Automatically scales to thousands of servers as traffic grows Highly Available Can always access your data Durable Data is replicated at least 3 times

31. Table Storage Capabilities What tables don’t do What tables can do             Not relational No Referential Integrity No Joins Limited Queries No Group by No Aggregations Transactions (limited) Very Scalable Flexible Durable Store LOTS of stuff  Cheap If these are important to you, use SQL Azure

32. Queue Service Store a queue of messages FIFO Can be used by multiple worker roles

33. Windows Azure Summary Many is better than one Let Microsoft worry about this Loose coupling Web Role and Worker Role Storage choice Azure Storage: Simple stores scale Table, Blob, Queue SQL Azure: Full RDBMS Stored Procedures, Schema, Transactions, Views etc

34. Windows Azure - Coming soon… Programming model Administrator privileges in the VM Deployment of pre-configured VM images Still obtain the benefits of the WA service model Storage User-selectable geo-locations for replicas Secondary indices on tables Service management Remote terminal server access to VMs

35. What’s in the cloud? Application Architecture

36. Architecture Quote: “Some architectures will require rework” All of them will require rework to do it right… Many application architectures not suited for large scale! I can go for multiple web roles But not for unlimited web roles…(think performance vs. overhead) Think in “multiple roles” Web roles Backedbyworkerroleswhereneeded Architecture will be one of the challenges

37. Typical Architecture Service Unavailable VIP Worker Role Web Role Windows Azure Storage (Blob, Table, Queue)

38. Web + Worker Role Service Model Worker Role Service Still Available Worker Role Web Role VIP Worker Role Web Role Worker Role Worker Role Windows Azure Storage (Blob, Table, Queue)

39. SB Pattern : Pub/Sub Publisher AppFabric Servicebus Multiple Subscribers

40. SB Pattern : Public REST service http://realdolmen.servicebus.windows.net/restservice/XXX/YYY AppFabric Servicebus Service

41. AccessControlHelper.DemandActionClaim(“ManagePrices"); ManagePrices

42. Access Control Service

43. SB Pattern : Access Control Access Control Service Access Control Service Unrelayed communication

44. What’s in the cloud? Getting started with Azure

45. What you will need… Tools Windows 2008, Windows Vista, Windows 7 (IIS7+) Visual Studio (or Eclipse if you want to go PHP/JAVA) Windows Azure SDK Use the Web Platform Installer www.microsoft.com/web Account http://www.microsoft.com/windowsazure/account
