The webMethods Integration Server hosts packages that contain services and related files. The server contains several packages.

For example, Packages that contain built-in services, which can be invoked from services or client applications and services that demonstrate features of the webMethods Integration Platform.

You can create additional packages to hold the services that your developers create. Developers can create services that perform functions, such as, integrating your business systems with those of your partners, retrieving data from legacy systems, and accessing and updating databases.

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.
