If you use a VPS for online and offline applications, you could come across a case where they don't function adequately as a result of lack of physical memory. This could take place if you try to run an app which requires more RAM than the amount your plan provides, or in the event that you have too many apps and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful package deal, this may happen if you include more programs on the server at some point, and since it is possible that you will require simply more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you'll be able to use without changing your entire plan. That way, you can pay only for the system resources that you really need and you'll be able to avoid errors on your sites caused by deficiency of memory and the inability of the Virtual Private Server to load the apps.
