Lots I could talk about…
• Why is PHP 5.3 faster on Windows than previous versions of PHP?
• Version 3.0 (beta) of the SQL Server Driver for PHP is available.
• SQL Server ODBC driver for Linux is coming.
• Hadoop for Windows Server/Azure is coming.
But I’ll tour Windows Azure(by looking at auto-scaling)

What type of cloud is Windows Azure?
What are Web and Worker roles?
Web Role• External Facing • HTTP/HTTPS
Endpoint• Short lived calls(Think Web Server)
Worker Role• Internal Facing • TCP/HTTP Endpoint• Long running
processes(Think Service or
Deamon)There is also a VM Role • You configure and maintain the OS.• Lacks persistent state.
In general, think of a “role” as on OS template.
Instance Sizes and Costs
Size Cores CPU Speed Memory Cost/hour
Ex. Small Shared 1.0 GHz 768 MB $0.04
Small 1 1.6 GHz 1.75 GB $0.12
Medium 2 1.6 GHz 3.5 GB $0.24
Large 4 1.6 GHz 7 GB $0.48
Ex. Large 8 1.6 GHz 14 GB $0.96
What is Azure Storage?
Blobs: large, unstructured binary data (audio, video, etc.)
Tables: simply (and loosely) structured data (not relational)
Queues: serially accessed messages
Storage Costs $0.14 GB/month*
$0.01/10k transactions
* http://blogs.msdn.com/b/windowsazure/archive/2011/10/27/microsoft-lowers-storage-cost-for-blob-and-table-storage-in-windows-azure.aspx
Transfer Costs $0.15 GB outbound

Containers and Blobs• Containers
– Multiple containers per account– Create/destroy on the fly– One container can hold up to 100 TB* worth of blobs– Set access policies (private, public read, full public read)– Set metadata
• No search/query (i.e. no WHERE MetadataValue = ?)
• Blobs– A blob can be up to 1 TB in size– Set access policy– Set metadata
*100 TB is the size limit for an entire storage account
What is the Diagnostics Monitor?An Azure component (MonAgentHost.exe) that collects diagnostic data for application instances– Starts automatically by default– Must define a storage account connection string
How does it work (in a nutshell)?
Role Instance Starts Diagnostic Monitor Starts Monitor is configured
Imperatively at Start time Remotely any time
Monitor buffers data locally User can set a quota (FIFO)
User initiates transfer to storage Scheduled or On Demand

What is the Management API?
• A REST API that allows you to manage services under an Azure subscription.– Examples include…
• Create/stop/start/delete a deployment• Move staging deployment to production• Increasing the number of instances• Initiate a rolling upgrade• Etc.• (almost anything you can do via the management portal)
• All API calls must be signed with an X509 certificate
Windows Azure SDK for PHP• http://phpazure.codeplex.com/
– Open Source project– Mostly platform independent (only the packaging tools have a Windows
dependency)
• Features – PHP classes for Windows Azure Blobs, Tables & Queues– Scaffolds for quick application deployment– Helper Classes for HTTP transport, AuthN/AuthZ, REST & Error Management – Manageability, Instrumentation & Logging support – Support for storing PHP sessions in Azure Table Storage – Management API client – Diagnostics client – Command line tools set for packaging, management , diagnostics, and deployment
