Scaling Out a Service in VMM

After you have deployed a service in Virtual Machine Manager (VMM) and you need to deploy additional virtual machines to a tier of the service, you can use the scale out functionality of VMM. For example, during the holiday shopping season, your website may need additional web servers deployed to handle the increase in traffic to your site.

When you create a tier in a service template, you can specify whether that tier can be scaled out and the minimum and maximum number of virtual machines that you can deploy in the tier. For more information, see How to Configure the Properties of a Service Template.

If you try to scale out a tier beyond its maximum tier size, you will receive a warning, but VMM will not prevent you from scaling out the tier. However, after the virtual machine is deployed, the tier and the service will show a status of Needs Attention in the VMs and Services workspace.
