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