John Bravenec from the Windows Azure team will provide an overview of the Service Management, Storage, Compute, and Developer Experience in Windows Azure. John will discuss how Windows Azure enables developers to focus on their business logic as opposed to operational details like patching OSs, maintaining servers, and ensuring fail-over.

1. Windows Azure  John Bravenec Lead Program Manager Windows Azure Microsoft

2. The Windows Azure Platform Web and clouds Third party cloud Web applications Compute Storage Management Management Relational data Connectivity Interoperability Access control On-premises On-premises systems Composite applications

3. Windows Azure is a place to run your applications.

4. Windows Azure is a cloudcomputing platform, so it’s designed to scale.

5. Windows Azure is a utility computing platform, so you pay for what you use.

6. Inside are many servers.

7. with VMs running Windows.

8. We call this the Fabric,

9. and it’s where your app runs. Your Application

10. Management tasks are automated by the Fabric Controller.

11. You tell the Fabric Controller what to do, and it figures out how to do it.

12. For this to work, you need to tell us about your application.

13. The Service Model What are the components (roles)? How do they interact? At what scale? Web role Worker role Web role Worker role Web role Worker role LB

14. Windows Azure does scale out.

15. Stateless compute + Durable storage = Scalable application

16. Storage is just another app. Storage Service

17. Durable Storage Three abstractions: Three replicas of everything Shared key authentication REST API Blobs Tables Queues …

18. Blobs Like files Up to 50GB each 8KB metadata each Stored in containers Public or private access at container level

19. Tables Entities with properties Non-relational Partitioned for scale No fixed schema ADO.NET Data Services

20. Queues Asynchronous message passing 8KB messages Two-phase commit …

21. Web role Worker role Web role Worker role Web role Worker role LB Storage Putting it All Together

22. Developer experience is key.

23. Making Your Life Easier Simulated cloud on your laptop Development fabric Development storage Local debugging Command-line + Visual Studio add-in ASP.NET providers Storage client library Management portal

24. Web Role Receives internet traffic Hosted by IIS Typically ASP.NET Partial trust

25. Worker Role Doesn’t receive internet traffic Runs forever .NET assembly Partial trust

26. Debugging Locally, what you would expect In the cloud, logging

27. Deployment and Maintenance Deploy Web portal Upload in browser or to storage APIs Upload to storage Maintain Scale, upgrade, reconfigure in portal, APIs Retrieve logs, set up alerts
