Data centers have an array of different components, but the three main elements are:
Power: ​All different types of hosting services and computing systems run on a reliable and constant power source. Most experts consider power as the holy grail of data centers.
Cooling System: Due to lack of proper ventilation systems, the IT equipment of a data center can quickly heat up, affecting its functioning. Thus, reputed data centers must install a suitable cooling system that keeps the hardware system airy and its functions seamless.
Security: All servers and hardware systems of a data center are hubs of sensitive data. A good data center should always have the highest level of protection to prevent data breaches.
