In the event that you use a Virtual Private Server for online and offline applications, you could come across a case where they do not operate correctly as a result of lack of physical memory. This may occur if you try to run an application that requires more RAM than the amount your plan offers, or if you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful plan, this may happen if you add more programs on the hosting server in the future, and since it is possible that you shall need only more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you can use without changing your whole plan. That way, you can pay only for the resources that you need and you shall be able to avoid errors on your sites caused by deficiency of memory and the inability of the Virtual Private Server to load the programs.
