A data center is a facility that keeps a lot of hosting servers. The machines could be employed for a variety of functions - hosting, file and image storage, computing, and so forth. All big companies that provide online services have their machines in one or a number of data centers since such a facility can offer the desired conditions and protection for the data located on the servers. This includes environmental adjustments for the humidity and temperature in order to ensure the maximum performance and long life of the web servers, backup power generators, hardware monitoring and last, but not least, physical security and safety as to make sure that your data can't be accessed by an unauthorized third-party. A inadequately performing data center could easily undermine the services which a firm supplies.
