We have evaluated an open-source option called OpenStack. However, we decided not to use OpenStack because staffing demands were too high. It's currently hard to find the right staff on the market. So we decided to use a complete solution and not an OpenStack solution.

We did not consider many other options when we evaluated this solution. The PoC was straightforward and it worked well in all of the scenarios. After that, it was deployed.

We are working with VMware Stack and we have got a customer that is deploying Cloud Director. Because they are a service provider, we are providing services to them and they are requesting services from us. But the reason we were looking at comparisons between vCloud Director and vRealize Automation is just to compare why the client would not want to go with a completely automated solution. We were subsequently able to clarify the situation and differences for them because of the product evaluations.  

We did evaluate other options, but vRealize Business for Cloud turned out to be the best.
