webMethods Integration Server provides an environment for the orderly, efficient, and secure, execution of services. It decodes client requests, identifies the requested services, invokes the services, passes data to them in the expected format, encodes the output produced by the services, and returns output to the clients.

Using Designer, you build and edit services, document types, and other elements directly on an Integration Server. You connect Designer to Integration Server through server definitions. A server definition specifies the location and characteristics of the Integration Server to which Designer is connecting.
