“The cloud” has become a buzzword over the years, especially within the business space. So what exactly is it? The cloud is a collection of data centers that are located all over the world. These data centers consist of servers that are accessed by users over the internet, and provide users with access to software and data. The cloud exists through virtualization, which is the process whereby physical computers, otherwise known as virtual machines, are mimicked using software. Many users can interact with these virtual machines at one time, where each virtual machine remains autonomous and doesn't interact with the others.
