What is vRealize Orchestrator?


VMware vRealize Orchestrator (vRO) is a a (mostly) GUI based application which can help you automate and orchestrate a wide range of tasks. Originally an application called Dunes Virtual Services Orchestrator, the company Dunes Technologies was purchased by VMware in 2007. Something of a hidden-gem, vRealize Orchestrator has since been included as part of vSphere and/or vRealize Automation entitlements.

As it’s interface is a little different to most other VMware products, it can be a little intimidating. Also, as with other automation solutions, VMware also have a tough job selling it (“What can I do with it?” … “Well, anything”). As such a lot of Administrators might be aware of it, but have probably been considering getting around to looking at it “some day”.

How can vRO help you?

vRO is an automation and Orchestration solution. You write Workflows which can then be executed. There are a number of pre-canned workflows which can be dragged-and dropped onto a new workflow to execute in sequence. Workflows can have multiple inputs, and you can make some reasonably presentable and simple to use forms.

From simple tasks (“Snapshot a machine”) to more complex, layered solutions with a number of external dependencies. Being VMware, it excels at managing vSphere machines, but it also provides a number of other integrations.

What can I automate with vRealize Orchestrator?

Out of the box vRO offers functionality to integrate with a number of VMware Products (vSphere, vRealize Automation, NSX) as well as Active Directory. There are also a number of plugins available for other vendor’s products (such as F5 and InfoBlox).

If you can’t find a plugin for your exact requirements, RO also has the ability to execute PowerShell and SSH on hosts, as well as making SOAP/REST calls to anything with an API.


I’m going to assume you’ve got as far as having a working vRO server, and you can get logged-in.
