My company has its headquarters in country A which is 600km away from the country I reside in. The main application server is in country A and they want to cluster it with a server in country B.

They've brought in a consultant to do the job but they're offering what I mentioned above:

Geo cluster using sql server 2016 EE using wsfc and AG and I think FCI but since I don't have experience in clustering or AG I'm trying to see what's best for the business and won't cause another layer of troubleshooting for myself and the network and system teams.

I'd still like to get someone else's view besides this 3rd company so I think I'll ask business to bring in another consultant.

What do you guys think?
