wow is cloud based nowâŚno more single realms per server and realms are connected.
That is the modern infrastructure that classic will run on.
How they set that up though to emulate how it used to be is something they havenât told us.

When World of Warcraft shipped it was on single realms that were completely independent from all other realms. Now weâre on a much more cloud-based infrastructure, which didnât exist in 2004 and is now the industry standard. Weâve modernized our game to make use of that, so we have a lot more resources we can share between different realms and a lot more connectivity we can provide to our players in their gameplay experience.
