What You Can Do with Rackspace Auto Scale

You can use Rackspace Auto Scale to perform the following tasks:

  • Add and remove a specific number of servers or a percentage of your total resources
  • Support your dedicated servers by adding—and removing—cloud servers based on a schedule

Prerequisites

Before you can use Rackspace Auto Scale, you need to have in place the following:

  • A Rackspace Cloud Server account. To sign up for a Rackspace Cloud account, go to the Rackspace Public Cloud signup page.
  • Server image or images that you have configured with all needed applications and settings, and that will be ready when the server is booted. You can do this with various programs such as Chef, Puppet, Salt, etc. You can create your image(s) with the API or through the Cloud Control Panel. See the Cloud Servers Developer Guide for information on the API.
  • (Optional)Load Balancer, one is allowed per group of 25 server images. You can create a load balancer with the API or the Cloud Control Panel. See the Cloud Load Balancers Developer Guide for information on the API.

Once you are set up, there are some concepts you should understand. We address those on the next page, Concepts.
