Services Provided: Co-Location vs Rented/Dedicated Servers vs Cloud

Quote: “in general – I suggest to have your first few servers rented, and think about scaling your load (including using cloud servers) while you’re running your playtesting/public beta/etc.”
Another Quote: “most likely to rent just the space in the datacenter is going to be more expensive that renting space plus servers-in-that-space. Don’t ask me why it is the case – but it usually is”

Preparing to Deploy your Game: To Cloud or Not to Cloud?

Quote: “In fact, the following “hybrid” model is more optimal than both pure cloud-based and pure rental-based ones”

TCP Peculiarities as Applied to Games, Part II

Quote: “Nagle’s algorithm aims to deal with those [CENSORED] developers who’re trying to send data over TCP in really small chunks (like 1 byte each time)”
Another Quote: “it seems that “proportional rate reduction” (PRR, reportedly used by Linux kernels by default starting from 3.2) performs for gaming purposes a little bit better than the alternatives”
