If you use a VPS for online and offline programs, you may come across a scenario where they don't work properly because of lack of physical memory. This could take place if you try to run a program that requires more RAM than the amount your package deal comes with, 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 the event that you get a powerful package deal, this may happen if you add more programs on the server in the future, and since it is possible that you will require just more physical memory, but not higher Processor speeds or more disk space, we offer a RAM upgrade that you could use without changing your entire plan. Thus, you may pay just for the system resources which you really need and you shall be able to avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the programs.
