In case you use a VPS for online and offline programs, you could come across a case where they do not work properly due to insufficient physical memory. This could occur if you try to run an application that requires additional RAM than the amount your package deal provides, or in the event that you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful package, this may happen if you add more apps on the server in the future, and since it's possible that you will require just more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you could use without changing your whole plan. Thus, you may pay only for the system resources that you need and you can avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the programs.
