    A Group Type defines logical grouping types for nodes, typically for different management
    purposes. Groups can effectively be viewed as logical nodes that are not part of the physical
    deployment topology of an application, yet can have capabilities and the ability to attach
    policies and interfaces that can be applied (depending on the group type) to its member nodes.

    Conceptually, group definitions allow the creation of logical "membership" relationships to
    nodes in a service template that are not a part of the application's explicit requirement
    dependencies in the topology template (i.e. those required to actually get the application
    deployed and running). Instead, such logical membership allows for the introduction of things
    such as group management and uniform application of policies (i.e., requirements that are also
    not bound to the application itself) to the group's members.
