Windows Clustering or Vmware 6.5 Fault Tolerance (Original Question has been edited where I had erroneously asked Windows Clustering or Vmware HA)
We are in the process of implementing virtual Fax Servers in our environment and one of the requirement is to create Windows Cluster.
We do have vSphere 6.5 with the required licenses.
Question: Cud I use VMWare HA instead. Is it better to use vMware HA or Windows Cluster?
Cud I have a good step by step guide how to set up both?
Thank you.

Can the fax service even be done as a Windows cluster, or is the cluster for the database?
VMware clustering and Windows clustering are very different. With VMware clustering, you have just 1 VM and it doesn't know that it is clustered. Clustering is all handled by the hypervisor. If the VM dies or the host dies, the VM needs to restart from an unexpected shutdown.
Windows clustering is handles by Windows OS. You need to have at least 2 VM running, and whatever service you're clustering needs to be cluster aware in most cases. Configuration is much more difficult for a Microsoft cluster.
There is also application level clustering, where the application is expressly designed for high availability without relying on the OS to provide clustering. Microsoft SQL has this, as one example.
