A data center could be identified as an advanced warehouse for hosting servers. That's a facility which holds a huge number of web servers used by businesses for storing content and files or for performing computation services at a huge scale. Web hosting, search engines and massive social networks are only several examples of the services that need data centers for their hosting servers since they can't operate on a single hosting server. The facilities deal with the temperature, humidity, electrical power and connection backups so as to guarantee the most efficient and continuous work of all servers stored there. All data centers include 24/7 monitoring and restrict the access to the servers so as to ensure that the servers are protected at all times. The quality of any Internet service you get usually depends not simply on the company you communicate with, but also on the data center facility they use.
