Well isn't everything "at scale" difficult? I just don't see what makes this special, dedicated servers don't require GPUs, just a good amount of cpu and a moderate amount of network bandwidth. This just feels more like branding existing things because games are "cool". I left that industry a few years back so maybe things have changed but I'm not seeing it.

Gameservers are very different in nature from the the rest of the industry ( like web services ), first of all everything is custom so it's not lile there are tools proprietary or open source for that. Even inside the same company you can have different engine with different matchmaking solution etc ... then you have to hook all of that on some platform ( cloud or bare metal ). The biggest hurdle is the cost, that the #1 issue people will have running gameservers. Imagine your game is using 1 core for 16 players, how many ec2 instance you need to accomodate 150K concurent users? ( and that's just the cost for gameservers it does not includes online services ). Now what's hard for example? DDoS protection, matchmaking, scaling up/down ( scaling down is challenging depending of the game because of server fragmentation), performance optimization, most dev use Windows to dev games but gameservers are more and more running on Linux now so how do you test that locally. The biggest challenge is that every games are different and you need something "custom" very often. Also game devs have NIH syndrom which doesn't help. Running gameservers for a serious game is not trivial, currently more challenging that puting some Java app behind a load balancer on an auto-scaling group.

  So... it's the same problems that we've always had hosting a dedicated game server fleet. Game solutions have always been custom because there's never some one-size-fits-all engine(although bless Unreal and Unity for taking a shot at it). I speak from real experience here here and not just some hypothetical stance. The design and structure of your game will have implications on how your matchmaking/sharding plays out across a region. Just because gamedev uses windows to a degree doesn't make Linux some big scary thing. PS3 was closer to Linux than anything else. I was running dedicated Linux servers for Half-Life/Quake/etc over 20 years ago so it's not like that's anything new. If you're doing matchmaking based servers that's the easy case. You don't have any shared state, you can scale down when a match ends. When you start crossing into the shared state(MMO, non-sharded worlds, etc) that's where it's not easy to just horizontally scale out.
