WoW: Forever launch used 70,480 CPU cores and 251 terabytes of RAM

The gaming company went to extraordinary lengths to ensure World of Warcraft: Forever's launch would be smooth, deploying an unprecedented amount of computing power. This infrastructure consisted of 3,924 virtual machines working in concert to handle millions of players simultaneously.

Each virtual machine was allocated approximately 18 CPU cores and 64GB of RAM, though Blizzard may have used a combination of different node configurations. The total setup required 70,480 CPU cores and an impressive 251 terabytes of memory to keep the game running without major technical issues.
