Question

Is it possible to trigger a resize of an Azure VM automatically based on a set condition?

For example, increase from a ‘Medium’ machine to ‘Large’ if the processor/RAM is over 90% usage out for 5 minutes? Then, obviously scale back down when usage reduces?

Or… is it possible to schedule a resize between (peak) UK office hours then downscale off-peak?

Just a thought…

Worth checking out the Auto Scaling Building Block from the patterns and practices team, part of the Enterprise Library 5.0 for Windows Azure

The Microsoft Enterprise Library Autoscaling Application Block
(WASABi) lets you add automatic scaling behavior to your Windows Azure
applications. You can choose to host the block in Windows Azure or in
an on-premises application. The Autoscaling Application Block can be
used without modification; it provides all of the functionality needed
to define and monitor autoscaling behavior in a Windows Azure
application.

The Enterprise Library Autoscaling Application Block includes the
following features:

• It allows you to use the graphical Enterprise Library configuration tool to manage configuration settings.
• It allows you to configure the storage locations and logging mechanisms used by the block.
• It allows you to extend the block by adding custom autoscaling rules and actions.
