While working together with Microsoft on the Windows Azure SDK for PHP, we found that we needed an popular example application hosted on Microsoft’s Windows Azure. Wordpress was an obvious choice, but not an obvious task. Learn more about Windows Azure, the PHP SDK that we developed, SQL Azure and about the problems we faced porting an existing PHP application to Windows Azure.

7. Agenda Cloud computing? Windows Azure? Application architecture Using PHP with Windows Azure Wordpress Resources Q&A

8. What’s in the cloud? Cloud Computing

9. 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)

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

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

12. Microsoft’s cloud Windows Azure

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

14. Windows Azure Flexible application hosting Lights-out service management Provide code & service model, hit ENTER Storage at massive scale Blobs, tables, queues Compute Storage Management There’s an SDK for this: http://phpazure.codeplex.com

15. Windows Azure

16. Windows Azure Data Storage Queue Blob Account Tables Drives

17. Storage options Blobs, tables, queues Windows Azure Drive (a.k.a. XDrive) Virtual NTFS volume that can be mounted .vhd format Use existing NTFS API’s Easier migration Stored on blob storage provides quick mount/unmount in other VM

18. SQL Azure Relational database as a service Highly available, automatically maintained Extension of the SQL Server Data Platform Reporting Data Sync Business Analytics Database There’s a driver for this: http://sqlsrvphp.codeplex.com

19. 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 High availability, DB provisioning, and DB management are provided by the service

20. Windows Azure AppFabric Secure connections between services Across organizational boundaries Claims-based access control ServiceBus AccessControl There’s an SDK for this: http://dotnetservicesphp.codeplex.com/

21. Service Bus Overview

22. Windows Azure AppFabric - Service Bus Securely connect applications Over the internet Across any network topology (= across firewalls!) 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

23. PortBridge - http://bit.ly/bCDrUs Bridge TCP over Service Bus A fun usage scenario…

24. Microsoft Codename “Dallas” Content brokerage and discovery platform Available as a CTP Microsoft Codename “Dallas”Information Services

25. Microsoft Codename “Sydney” - Connectivity WINDOWS AZURE PLATFORM ENTERPRISE Data Service Service Bus Access Control Service Code Name “Project Sydney”

28. Developer tools Development Use your favourite editor Local debugging Windows with IIS 7.x Visual Studio Windows Azure tools for Eclipse Packaging Windows Azure SDK Deployment Any browser

39. Finally! Wordpress

40. Blogging engine Widely used Easy installation Gazillion plugins Huge community around it Free and open-source Wordpress

41. Runs on top of MySQL Has no database abstraction layer So: only runs on MySQL Windows Azure has Table Storage and SQL Azure I feel lots of work coming… But...

43. Easy way out Wordpress on Windows Azure MySQL on-premise / at other hoster Medium way out Wordpress on Windows Azure MySQL as well Hard way out Wordpress on Windows Azure MySQL out, SQL Azure in There are ways around!

44. The easy way out Windows Azure Storage VIP Load Balancer PHP Web Role MySQL Windows Azure Platform On-Premise / hosted

45. The easy way out Fresh Windows Azure project in Eclipse Fresh Wordpress.org download Point wp-config.php to some MySQL server Package & deploy

46. The medium way out Windows Azure Storage VIP Load Balancer PHP Web Role WorkerRole runningMySQL Windows Azure Platform On-Premise / hosted

47. Fresh Windows Azure project in Eclipse Fresh Wordpress.org download “Windows Azure MySQL PHP Solution Accelerator” http://code.msdn.microsoft.com/winazuremysqlphp Some configuration Some anger Some configuration Point wp-config.php to the above MySQL server Package & deploy The medium way out

48. BUT! Instance count! Pricing! (5 x 240 EUR / month adds up...) Easier migration, but at a cost... The medium way out

49. Yes, you can run MySQL on Windows Azure! More “solution accelerators”: MySQL http://code.msdn.microsoft.com/winazuremysqlphp Memcached http://code.msdn.microsoft.com/winazurememcached MediaWiki http://code.msdn.microsoft.com/winazuremediawiki Tomcat http://code.msdn.microsoft.com/winazuretomcat So...

51. Fresh Windows Azure project in Eclipse Fresh Wordpress.org download Point wp-config.php to SQL Azure Package & deploy Fail! There’s no SQL Server / SQL Azure support in Wordpress, remember? The hard way out

52. MySQL queries all over the place! “Data layer” (wp-db.php) = very thin Raw MySQL queries passed from app to db Logging Some other stuff That’s nowhere near a database abstraction... Have you ever looked at Wordpress?

53. Required: Re-build wp-db.php using SQL Server Driver for PHP http://www.microsoft.com/sqlserver/2005/en/us/PHP-Driver.aspx Options... Re-write every single query in Wordpress Future proof? Insane! Build a query translation tool, rewriting queries on-the-fly Future proof! Insane! Strategic options
