A virtual or a dedicated hosting server is a standalone machine, which has its own Os and maintaining the latter up-to-date is an important, although underrated task. Not only can an update boost the general performance of your internet sites, but it can also save you a lot of problems in the future. An update can be released for a variety of reasons, the most widespread being to fix recently discovered security holes, which may allow third-party people to access and modify the content that you have on the hosting machine. You may also see an improved functionality of your web apps because updates can also be released for better compatibility between the Operating System and the configuration it functions on so that you can get the most out of the hardware. Furthermore, if you keep your programs up-to-date, they may also need a later Operating system version which will have the required software dependencies and will permit them to operate adequately.
