While many businesses and large organizations still hold their own data and servers on site, the industry has recently seen the growth of large specialist datacentres both for data storage and hosting. That includes dedicated hosting, because while there is no cost sharing involved at the server level, purpose-built datacentres do provide cost sharing advantages in other areas. Climate control is one of the simplest. We all know that any mainframe or bank of servers (or even any laptop computer) puts out heat that needs to be removed from the area. Otherwise the machines will eventually fail. For some, it’s as simple as finding a dedicated server room that can be kept several degrees cooler than the rest of the office despite that heat output, but the larger the machines, the harder that will be. Sharing a space built with HVAC (Heating, Ventilation, and Air Conditioning) for large electronics in mind can significantly reduce the costs involved. A good datacentre will also have electrical power redundancy built in. That really can be difficult to supply in-house, and a surprisingly significant number of businesses don’t even consider power redundancy when housing their own servers and creating data storage and backup facilities. The HVAC systems in particular may not have power failsafes installed. And of course, there is security, both physical and network. Any datacentre should take their security extremely seriously, and most will have the staffing expertise to back that concern up. Access to each room needs to be strictly controlled- the server room in many office blocks is just protected by a locked door and not monitored at all, despite the high value of what’s in there. The data flowing in and out of the facility needs to be closely monitored as well, 24 hours a day every day of the year. That is much more achievable in a datacentre.
