With the vRealize Orchestrator plug-ins, you can access and control external technologies and applications. Exposing an external technology in a vRealize Orchestrator plug-in lets you incorporate objects and functions in workflows and run workflows on the objects of that external technology.
The external technologies that you access by using plug-ins include virtualization management tools, email systems, databases, directory services, and remote control interfaces.
vRealize Orchestrator provides a standard set of preinstalled plug-ins, which expose the VMware vCenter Server API, email and authentication capabilities, and other technologies. In addition, the vRealize Orchestrator open plug-in architecture lets you develop plug-ins to access other applications. vRealize Orchestrator implements open standards to simplify integration with external systems.
The standard set of plug-ins is automatically installed with the vRealize Orchestrator server. You might need to configure some of the plug-ins, for example the vCenter Server plug-in, before you start using them.
