3. Windows Azure 6-10-2011 Cloud Operating System

4. Windows Azure Service Architecture 6-10-2011 Storage LB Windows Azure Data Center LB LB The Internet The Internet via TCP or HTTP

5. Worker Role Patterns Queue Polling Worker Poll and Pop Messages within while(true) loop E.g. Map/Reduce pattern, background image processing Listening Worker Role Create TcpListener or WCF Service Host E.g. Run a .NET SMTP server or WCF Service External Process Worker Role OnStart or Run method executes Process.Start() Startup Task installs or executes background/foreground process E.g. Run a database server, web server, distributed cache 6-10-2011

6. Web Role All features of a worker role + IIS 7 or 7.5 ASP.NET 3.5 SP1 or 4.0 – 64bit Hosts Webforms or MVC FastCGI applications (e.g. PHP) Multiple Websites Http(s) 6-10-2011

7. Virtual Machine Role Provided to help you move applications to Windows Azure Enables you to have full control over the OS Image Create your VHD locally Upload the VHD to storage Deploy a service package that uses the custom OS image The role is your VM – Specify <OsImage href=&quot;20101020BaseVM.vhd&quot; /> in the .cscfg Key considerations Image must be Windows Server 2008 R2 Enterprise Designed for long or non-automated installs No durability of OS image You configure and maintain the Operating System Currently available as a limited beta 6-10-2011

9. Azure Storage 6-10-2011 Blobs Tables Queues Storage HTTP

10. Windows Azure Storage Account User specified globally unique account name Can choose geo-location to host storage account US – “North Central” and “South Central” Europe – “North” and “West” Asia – “East” and “Southeast” Can CDN Enable Account Blobs delivered via 18 global CDN nodes Can co-locate storage account with compute account Explicitly or using affinity groups Accounts have two independent 512 bit shared secret keys 100TB per account 6-10-2011

12. How Windows Azure Drives Works 6-10-2011 Drive is a formatted page blob stored in blob service Mount obtains a blob lease Mount specifies amount of local storage for cache NTFS flushed/unbuffered writes commit to blob store before returning to app NTFS reads can be served from local cache or from blob store (cache miss) Windows Azure Blob Service Application Lease Drive X:

13. Table Storage Concepts 6-10-2011 Entity Table Account contoso customers Name =… Email = … Name =… EMailAdd= … photos Photo ID =… Date =… Photo ID =… Date =…

14. Table Storage 6-10-2011

15. Queue Storage Concepts 6-10-2011 Message Queue Account order processing customer ID order ID http://… customer ID order ID http://… adventureworks

16. Loosely Coupled Workflow with Queues 6-10-2011 Enables workflow between roles Load work in a queue Producer can forget about message once it is in queue Many workers consume the queue For extreme throughput (>500 tps) Use multiple queues Read messages in batches Multiple work items per message Queue Input Queue (Work Items)
