In case you use a VPS for online and offline applications, you could come across a case where they do not work adequately because of insufficient physical memory. This could occur if you try to run a program which requires more RAM than the amount your plan offers, or in case you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful package deal, this may happen if you add more apps on the hosting server at some point, and since it is possible that you shall need just more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you may use without changing your whole plan. Thus, you'll be able to pay only for the system resources that you really need and you can avoid errors on your sites caused by a lack of memory and the inability of the Virtual Private Server to load the programs.
