Cloud computing, many don't understand what it is, but simply put, cloud computing is storing information on remote servers for easy retrieval by users worldwide.
There are many advantages to cloud computing including centralization, security, data loss prevention, reliability, accessibility and low cost, to name a few.
Cloud computing too cuts maintenance, equipment and repair costs way down to almost nothing. All of these advantages and many more are the reason cloud computing is taking over so rapidly.
Given the growth of cloud computing, it will most probably take over most of the prevalent in-office systems within a few years.
