Always On VMs / Containers

I'm new to Proxmox and I'm a little lost. I have the system setup, Client side resources (VMs / Containers) fail back n fourth and i can manually migrate. The problem I have is when a node is down, a resources sessions are terminated and that resource is shutdown, migrated to another node and then restated. As an example issue, If a user is editing a MS Word document and the host node fails, that document is closed, any unsaved data is lost and the document runs the risk of being corrupted. How do I keep the resources in an "Always On" or Active/Active state?
Hmm, you mean active live replication of a VM? So that it runs, for example, twice in the cluster at the same time, and if one fails the other continues to run?

That is currently not possible with Proxmox VE, I'm afraid.
Such a feature can often be implemented on application level, though, where it can be done with using much less resources and being not so error prone as a VM CoLocation.

How and if that can be done depends on what runs inside the VM, or better said what service it should provided to users.
