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

APRIL 11, 2023 | SLIDE 6

What’s in the cloud?CLOUD COMPUTING

APRIL 11, 2023 | SLIDE 7

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)

APRIL 11, 2023 | SLIDE 8

DEFINITION OF CLOUD (NIST)

On-demand self service Standardized access Location independant resource pooling Rapid elasticity Pay per use

THE WINDOWS AZURE PLATFORM

Windows Azure SQL Azure Windows Azure platform AppFabric Microsoft Codename “Dallas”

APRIL 11, 2023 | SLIDE 12

AZURE SERVICE PLATFORM

Windows Azure is an Operating System as a Service for the Cloud.

Compute – auto-provisioning 64-bit application containers in Windows Server VMs; supports a wide range of application models

Storage – highly available distributed table, blob, queue, & cache

Languages – .NET 3.5 (C#, VB.NET, etc.), IronRuby, IronPython, PHP, native Win32 code

SQL Azure is a Relational Database for the Cloud.

RDBMS – Tables, Views, Indexes, Stored Procedures, Triggers, ...

Programmability – Managed ADO.NET data access, native ODBC, support for PHP

Tools – SQLCMD and the SQL Azure Database account portal

AppFabric is the glue between on-premises and the cloud.

Service Bus – connectivity to on-premises applications; secure, federated fire-wall friendly Web services messaging intermediary; durable & discoverable queues

Identity Management – rules-driven federated identity; AD federation; claims-based authorization

Live Services is a building block within the Azure Services Platform.

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

There’s no SQL Server / SQL Azure support in Wordpress, remember?

APRIL 11, 2023 | SLIDE 46

HAVE YOU EVER LOOKED AT WORDPRESS?

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...

APRIL 11, 2023 | SLIDE 47

STRATEGIC OPTIONS

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!

APRIL 11, 2023 | SLIDE 48

HERE’S WHAT WE DID...

Hooks in Wordpress Wp-contents/db.php Wp-includes/wp-db.php

Strategy Create wp-db.php class on top of SQL Server Driver for PHP

http://www.microsoft.com/sqlserver/2005/en/us/PHP-Driver.aspx Create custom DB schema, compatible with SQL Server Build a query translation tool, rewriting queries on-the-fly

Someone at Microsoft had this laying around

BUT THERE’S ALSO... RESOURCES

Resources Images, other file uploads, ...

Normally stored on server disk But this may not survive on Windows Azure...

BEFORE SKIPPING TO Q&A...

Is the source code available? No, not at this time.

Do I need Visual Studio / Eclipse? Only for local debugging.

Do I need Windows & the Windows Azure SDK? Only for packaging. I’ll keep whining to make this available on Linux.
