With vROps 7.0 and vRealize Ochestrator MP 2.0 you are able to use custom workflows.
You then can use custom workflows as an action in vROps.
Is that what you are looking for?
You've posted this in the vROps subforum, but it really sounds like you're wanting to develop a custom XaaS action to use in vRA. If that's the case, you can start with some of the examples in the library within vRO. It's not that hard to limit the reconfigures to CPU and Memory only.
