If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...
If you have a not-so-usual solution for your problems but need to justify it to your boss...
If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...
...then 'No Bugs' Hare on Soft.ware might be the right place for you.

D&D of MOGs: Vol. VII-IX (1st beta), page 4:

Scaling Stateful Objects

Quote: “it is DB which is usually The Bottleneck™ – it means that we’re saving this enormous amount of load, exactly where it really matters.”
Another Quote: “as discussed above, the real-world task is always about scaling the whole system, including database; and in this regard Stateless-App-based systems exhibit significant problems.”
[]

Docker and MOGs

Quote: “Contrary to popular belief, there are benefits of Docker containers which go beyond providing poorly written programs with exact versions of their dependencies”
Another Quote: “I do not buy a rather popular argument that “to achieve scalability, apps and middleware should be stateless””
[]

DevOps for MOGs

Quote: “This communication channel (coming from Operations back to Development) is extremely important to have a game which is able to work anywhere-reliably in the real world”
Another Quote: “Most importantly, our processes should allow these different production cycles to co-exist.”
[]

Databases and RAIDs

Quote: “for quite a few applications out there, the most important feature of the RAID is not even redundancy, but greatly improved write latency. Moreover – this is the thing which we cannot possibly get from software RAID (!).”
Another Quote: “As a rule of thumb – I am trying to keep the size of OLTP DB small enough to fit into RAM of the OLTP DB Server.”

Configuring Hardware for MOG. Part I (Switches, Firewalls, Game Servers)

Quote: “beware: “there are distros beyond the RedHat/Debian dichotomy – but if you’re reading this section looking for my advice on it – most likely you still have too little experience running Linux to look in that direction”
Another Quote: “every time I disable Active Directory Service from a production server – I feel as a doctor who successfully removed a cancer tumor from a patient”
