Fault tolerance 1s SQL in terminal access?

Question

Clusters

Friends, the question arose how to improve the fault tolerance of 1c sql?
I planned to simply deploy a cluster at the 1s level on 2 physical servers, and configure mssql in the always on mode on the same physical servers, but the problem is that 1s is used in the terminal. It turns out it seems like you also need to raise the cluster at the terminal server level? The end result is some kind of monster.
I began to look towards the hyper-v cluster, but there is little information, and it seems that I misunderstand the essence of the hyper-v cluster (I assumed that I get one OS from two physical servers, where, in turn, I configure all the services in a "single" version , and fault tolerance at the level of the entire OS.)
