I don’t know what server you call home, but other than the first day of in game holiday events, I have not seen anywhere near 150 people around the AH at any time in years on Cenarius.
In fact, I do not remember the last time I saw even close to 100 people around the AH.
I have worked in Corporate Information Technology for 15 years – companies were beginning to implement virtual servers in 2008 (VMware / Novell / Citrix etc) and I guarantee you it’s mainstream across the board now - no matter which sub-division of Information Technology you are branched in.
It makes financial and administerial sense. Blizzard are too large a company not to do it.
I posted two YouTube videos earlier in the thread as evidence. One is as recent as last year, and both are from time periods after Blizzard had switched from their old servers to the new ones.
The strange thing is that the servers have become less able to handle a large number of players. Is the crutch of sharding responsible? The game is designed and optimized for a very limited number of players, and when it goes beyond that bad things happen?
If that’s the case, like I said earlier…they need to find another solution.
Also to throw it out there - the virtual server itself is not limited as the cause of any crashes. It is also running a Database, is linked to storage space (Most likely a SAN) - it is running multiple services that are in relation to running the operating system which is hosting the “game server” (Not to be confused with the Server which is running the game server.)
When a server ‘crashes’ in WoW - all we see is a connection to the realm being cut off.
I’m not saying these to rationalise instability in a connection - just to highlight that there is more to these setups than Blizzards inhouse software and it is unfair to always point the finger at just them.
I’ve fixed too much software from Microsoft, Citrix, Novell and VMware to accept that Blizzard and Blizzard alone are to blame for every crash.
Because the servers aren’t configured for it, it’s no longer expected player behavior to congregate in that manner. In Classic it will be so they will have to configure the servers differently.
