In the event that you use a VPS for online and offline programs, you could come across a case where they do not work properly as a result of insufficient physical memory. This can occur if you try to run a program which requires additional RAM than the amount your package provides, or in case you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful plan, this can happen if you add more programs on the server at some point, and since it's possible that you will need only more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade that you can use without changing your entire plan. This way, you'll be able to pay only for the resources that you need and you'll be able to avoid errors on your Internet sites caused by deficiency of memory and the inability of the VPS to load the applications.
