What are the opensource alternatives for the VMware Horizon Suite that can integrate with the VMware VC? I have a VMware vCenter that is in charge of the VMS my company has. I would like to make my life easier and basically create a web interface where users could set up their own machines. This depends on how much resources they have been allocated, basically a cloud. What are free alternatives to the VMware vRA?

I am looking for new DevOps tools that I could learn and offer as a service to my company, we already use AWX,Vault,Git,Jenkins and have them all provided as a service, what other technologies could make our life easier as an IT company
