In case you use a VPS for online and offline apps, you may come across a situation where they do not perform correctly because of insufficient physical memory. This could happen if you try to run a program which requires additional RAM than the amount your plan includes, 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 the event that you get a powerful package deal, this can happen if you include more apps on the web server at some point, and since it's possible that you shall need just more physical memory, but not higher Processor speeds or more disk space, we offer a RAM upgrade that you'll be able to use without changing your entire plan. Thus, you'll be able to pay just for the system resources that you really need and you can avoid errors on your sites caused by deficiency of memory and the inability of the Virtual Private Server to load the programs.
