All large firms which supply online services have their servers in one or numerous data centers since such a facility can supply the required environment and protection for the info located on the servers. Including environmental settings for the humidity and temperature in order to ensure the maximum performance and long life of the servers, backup generators, hardware monitoring and last, but not least, physical security as to make sure that your information can't be accessed by an unauthorized third-party.
