We have a typical environment with dev, test, and production servers. the domains are dev.ourdomain.com, test.ourdomain.com, and www.ourdomain.com. If we go with "domain" license - do we need one license or three (we do want to test the application including the chat feature before we deploy it to production ;/ )

 

Similar, if we go with IP license: we have only one externally-facing IP address, but it's the address of load balancer, not the server. There are two servers in test and prod, and one server in dev. How many licenses do we need?

 

Or "small business license" is what we need?

 

Thanks
