I am actually working on a project right now to integrate WFA with vCenter Orchestrator and ultimately with vCloud Automation Center. We are still early in the stages though I do have vCO calling WFA to execute workflows. Full integration with vCAC and WFA is on that roadmap. Once we are complete, I will be publishing a joint TR with VMware on this solution. Ping me offline if you would like more information on this joint solution.
We just completed our basic testing today, using web services to call the WFA jobs from Dynamic Ops. The customer selects their needs from a web portal, it is passed over to DO, they process the variables, and call our WFA job.
This is a simple create a volume, add it to a vfiler, export it - all for Linux. We have yet to test the version with SnapMirror, I hope we are ready to test that on Jan. 2.
