VMware™ vRealize Orchestrator is a development- and process-automation platform that provides a library of extensible workflows. By using the workflow library you can create and run automated, configurable processes to manage the vSphere infrastructure as well as other VMware and third-party technologies.
Orchestrator exposes every operation in the vCenter Server API and so that you can integrate all of these operations into your own automated processes.
To run and schedule workflows on the objects in your vSphere infrastructure by using the vSphere Web Client, make sure that you configure the Orchestrator server to work with the same Single Sign-On instance to which both the vCenter Server and vSphere Web Client point. You must also ensure that Orchestrator is registered as a vCenter Server extension. You register Orchestrator as a vCenter Server extension when you specify a user (by providing the user name and password), who has the privileges to manage vCenter Server extensions.
