In this piece, we will focus more on scalability – which I simply define as the ability of a server to efficiently adapt to more load. It is more complex as that sounds and to know more, you can check out scalability @ wikipedia.
VPS stands for Virtual Private Server, a type of hosting technology that gives you advanced features and server privilege as against a shared hosting. Its use in this article however refers generally to any type of hosting that allows you root access to your server – dedicated servers, VPS itself and Cloud servers as examples. I’d like to explain each in here but that is beyond the scope of this piece. Maybe some other time ;)
