Whether or not you are familiar with them, data centers are what keep the internet running. They can be defined best as facilities which maintain all of the computer systems and components of a given network. It should be no surprise that the smooth operation of data centers can require a great deal of preventative care, especially when it comes to the environment. Power is a priority, so redundant and backup sources are frequently installed to keep networks going in the event of an outage or other emergency. This is especially important when dealing with large scale data centers that can use as much electricity as a small town. Redundant data communications connections are another preventative measure often taken should there be an incidence of device or utility failure.
