If you use a VPS for online and offline apps, you might come across a situation where they do not operate effectively because of insufficient physical memory. This may occur if you try to run a program that requires additional RAM than the amount your package offers, or if you have too many apps 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 may happen if you add more programs on the web server later on, and since it's possible that you shall need only more physical memory, but not higher Central processing unit speeds or more disk space, we provide a RAM upgrade that you can use without changing your entire plan. Thus, you'll be able to pay only for the resources that you really need and you shall be able to avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the programs.
