What is a ServerTemplate?
A RightScale-specific, reusable component that defines the characteristics of a cloud server in a way that is repeatable across multiple servers, clouds, and deployments. A ServerTemplate includes one or more MultiCloud Images used to define an operating system and supporting applications for the server, and a collection of RightScripts or Chef recipes that install select applications and define configuration settings and other attributes.
More exhaustive information about a ServerTemplate can be found in the Dashboard Users Guide under ServerTemplates.
