@MasterDarkwingz The issue in this case is more likely Sega not understanding Azure. In one of the interviews, they said they were still trying to figure out how Azure works. Unlike SE, Sega doesn't directly deal with the server hardware since they are essentially renting cloud servers from Microsoft, which automatically scale the cost to the number of active users, assuming they have things properly setup. The most Sega should have to deal with is perhaps increased rental costs.
SE, on the other hand, has traditional servers that they directly manage and thus has to actually buy the hardware themselves. So they have to actually deal with purchasing their own hardware.
If FFXIV is faster, that just goes to show how much more optimized it is compared to PSO2/NGS.
