I'd be curious to hear how people have used vCO (aka vcenter Orchestrator). I'm looking at it now and wondering how people use in their environments. I've used System Center Orchestrator (aka Opalis).
VMware vCenter Orchestrator is a development- and process-automation platform that provides a library of extensible workflows to allow you to create and run automated, configurable processes to manage the VMware vSphere infrastructure as well as other VMware and third-party technologies.
Orchestrator exposes every operation in the vCenter Server API, allowing you to integrate all of these operations into your automated processes. Orchestrator also allows you to integrate with other management and administration solutions through its open plug-in architecture.
You get started at:
Customers use it for any integration / automation tasks with any system in their datacenter or outside (public cloud / apps). Use cases are for provisioning / operations / portal back ends
I have seen from simple snapshot automation tasks to bare metal -> SAP landscape provisioning. Several service providers use vCO as their public cloud engine, enterprises use it for private cloud.
We use it for quite a few different use cases. We are heavily leveraging it in our vCloud Director and vCAC environments to fill the gaps we encounter with those products and to enable integration with other systems we rely on for the lifecycle management of the virtual systems and also the configuration management of those systems.
