In case you use a Virtual Private Server for online and offline programs, you may come across a scenario where they don't work correctly due to lack of physical memory. This could take place if you try to run an app that requires additional RAM than the amount your plan includes, or in case you have too many programs and some of them consume all 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 add more applications on the web server at some point, and since it's possible that you will require only more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you could use without changing your whole plan. Thus, you can pay just for the resources that you 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.
