Cluster arbitration needs a third computer hosting a share folder as judge to facilitate automatic failover between two computers hosting high available service.
However it was costly to have one. It must be joined to domain, must not be a domain controller and must not be down and can't be in DMZ as domain authentication must also succeed.
That is really easy on hardware and software. Good News is MS Windows Server 2019 remove ALL! of these requirements.
This means NO kerberos , NO domain controller , NO certificates , and NO Cluster Name Object needed. While we are at it, NO account needed on the nodes. Oh my!!
Just use even your router's USB share to arbitrate your internal clusters !!!!
Now it does make a lot of sense to use your cloud machine to arbitrate your internal on premise cluster setups!!!
Just need that atleast SMB 2.0 level file sharing is supported by your shares.
