Today we launched Auto Scale, one of the most exciting new features of the Rackspace Cloud. Auto Scale is the easiest way to make your Rackspace Cloud react automatically to changes in the demand your users place on your application. By creating a few simple rules based on thresholds that you define and control, you let us know when and how to grow (or shrink) the web or application tiers in your cloud.
The biggest benefit of the cloud is its ability to scale. Today, we make that easier with Unlimited Availability of Rackspace Auto Scale—a new tool that empowers you to grow or shrink your cloud dynamically. The product is offered for free to Rackspace customers, though you will still be charged for the cloud servers you utilize in scaling.
