BlueServers presents an ultimate guide on what are the differences between Dedicated Server, Shared Server, and Virtual Private Server. Grab some coffee and prepare for a 5-10 minute read. Some of the positions might seem similar but this is a deceiving feeling. Anyway, let’s get started.

That’s why people have invented RAID arrays, so the data keeps being operational at all times.
