Server, Data Center, Cloud Computer: the oil wells of the 21st century. While data processing can take place on a local computer (or in a paper folder for that matter), in today's world it most often happens on such servers – or a whole server farm – connected to a network. This kind of data processing provides ease of access, use, and transfer of data. Yet the sheer amount of data that can be operated on by advanced algorithms and self-learning machines, or worst case stolen by malicious actors, requires adequate data protection.
