In case you use a VPS for online and offline programs, you could come across a scenario where they don't function properly as a result of insufficient physical memory. This can take place if you try to run a program which requires additional RAM than the amount your plan comes with, or in the event that you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful package deal, this can happen if you add more apps on the server later on, and since it is possible that you'll need only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade which you can use without changing your entire plan. This way, you can pay just for the system resources which 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 applications.
