What is a Data Center?
A datacenter is a room with complete security for the servers as well as environmental considerations such as cooling requirements. A datacenter is also called as lights out server room that contains lock and key and kept in the dark. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices.
A Data Center is also called a Server Farm used to house computer systems and associated components, such as telecommunications and storage systems.
Data Centers are authorized subordinate organisations by Internet Registries. Data Centers play an important role between the RIR – Regional Internet Registries and the Internet User as route the network to access the data from any part of the world. The server’s on the internet are located at Data Centers. The boom of data centers came during the dot-com bubble. Companies needed fast Internet connectivity and nonstop operation to deploy systems and establish a presence on the Internet. Installing such equipment was not viable for many smaller companies. Many companies started building very large facilities, called Internet data centers (IDCs), which provide businesses with a range of solutions for systems deployment and operation.
