6. Windows Azure Basics Windows Azure can potentially provide various kinds of Windows-based environments The current Community Technology Preview (CTP) release supports both.NET and unmanaged applications More might appear before general availability

8. Windows Azure Compute Service Points of interest The VMs are provided by a cloud-optimized hypervisor They run 64-bit Windows Server 2008 Each VM has a one-to-one relationship with a processor core For developers: It’s mostly standard Windows and.NET A few things require accessing the Windows Azure Agent, e.g., logging A desktop facsimile of Windows Azure in the cloud is provided for development

9. … Fabric Compute Storage Application Windows Azure Storage Service A closer look Blobs HTTP/ HTTPS TablesQueues

10. Windows Azure Storage Points of interest Storage types: Blobs: a simple hierarchy of binary data Tables: entity storage (not relational tables) Queues: allow communication among web and worker role instances Access: Data is exposed via a RESTful interface Data can be accessed by: Windows Azure applications Other on-premises or cloud applications

11. Table... Table Entity... Entity Property... Property Windows Azure Storage A closer look at tables Name Type Value

12. Windows Azure Storage Tables: Challenges Access via REST You can’t use ordinary ADO.NET No SQL No real joins, aggregates, etc. An unfamiliar hierarchical structure You can’t easily move relational data to it Supporting services are scarce, e.g., reporting No schema

13. Windows Azure Storage Tables: Strengths Massive scalability By effectively allowing scale-out data Applied to the right problem, Windows Azure Tables are a beautiful thing Amazon, Google, and others provide quite similar technologies This appears to be the state of the art for scale-out data

14. Web Role Instance Queue 1) Receive work 3) Dequeue message 4) Do work 2) Enqueue message 5) Delete message Worker Role Instance Windows Azure Storage: Queues The suggested application model

16. Using Windows Azure Some examples A start-up might create a new Web application on Windows Azure They can fail fast or scale fast An ISV might create a SaaS version of an existing.NET application on Windows Azure It’s.NET, so porting the code is doable An enterprise might build a new application on Windows Azure It’s.NET, so developers are plentiful

27. Using SQL Services Some examples A Windows Azure application might use SQL Data Services for its data A departmental app could use SQL Data Services rather than a local database For better reliability and availability An organization might make data available to both in-house and partner apps through SQL Data Services Such as a company with a far-flung dealer network An enterprise might sync distributed data with the “Huron” Data Hub

29. .NET Services Windows Azure Live Services Applications SQL Services Others Windows Mobile Windows Mobile Windows Vista/XP Windows Vista/XP Windows Server Windows Server Service Bus Access Control ? ? Workflow.NET Services Infrastructure in the cloud

30. The Access Control Service The problem: Different organizations identify users with tokens containing different claims Applications can be faced with a confusing mess The solution: The Access Control Service implements a security token service (STS) in the cloud It accepts one token and issues another The claims in the outgoing token can differ from those in the incoming token An administrator can define rules for how this claims transformation is done

31. Service Bus The problem: Exposing internal applications on the Internet isn’t easy Network address translation (NAT) and firewalls get in the way The solution: Service Bus provides a cloud-based intermediary between clients and internal applications It also provides a service registry that clients can use to find the services they need

32. Access Control Service Bus Workflow Service Bus Registry Endpoints Organization Y Organization X Application Service Bus 2) Discover endpoints 1) Register endpoints 3) Access application

33. The Workflow Service The problem: Where should workflow logic that coordinates cross-organizational composite apps run? The solution: The Workflow Service runs WF-based workflows in the cloud There are some limits on what WF activities can be used No Code activities, for example

34. Using.NET Services Some examples An app that’s accessed over the Internet from different organizations might rely on Access Control to rationalize the identity information it receives And to do access control An enterprise might expose an internal application to its trading partners via Service Bus A group of trading partners might use Workflow to automate their cross-organizational business process

35. Conclusions Cloud platforms are here Microsoft is placing a big bet with the Azure Services Platform A new world is unfolding Prepare to be part of it
