Autoscaling in Windows Azure

One thing I really miss is the the opportunity to auto-scale applications in Windows Azure.

You can get around this by yourself, but it requires some creativity.

“…this release includes a comprehensive set of technical content, including:

  • Two new application blocks:
    • Autoscaling Application Block (“Wasabi”) to help you to automatically scale both web and worker roles in Windows Azure by dynamically provisioning/decommissioning roles or throttling.
    • Transient Fault Handling Application Block (“Topaz”) to help you make your Windows Azure application more resilient to transient errors when you are using these cloud services: SQL Azure, Windows Azure Storage, Windows Azure Caching, and Windows Azure Service Bus.
  • One new configuration source:
    • Blob configuration source to load configuration information from a blob in your Azure Storage account so that you can modify it without having to redeploy your application to Windows Azure.
  • Windows PowerShell cmdlets to browse and manipulate the Autoscaling Application Block settings directly from Windows PowerShell.
  • Protected configuration provider to allow you to encrypt sections of your configuration files in Windows Azure.
  • Updated database creation scripts so that you can migrate your code using the database trace listeners of the Logging Application Block and the Caching Application Block.
  • A substantial collection of experience guidance help you ramp up quickly, including:

The recommended way to obtain the Enterprise Library Integration Pack for Windows Azure is as NuGet packages. You can also download self-extracting zip files with binaries, sources (including tests) and the reference implementation from MSDN. The configuration tool is available as a Visual Studio extension package (VSIX) from the Visual Studio Gallery. “
