If you use a Virtual Private Server for online and offline programs, you may come across a scenario where they do not function properly as a result of insufficient physical memory. This could occur if you try to run a program that requires more RAM than the amount your plan comes with, 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 can happen if you add more apps on the web server later on, and since it is possible that you will require only more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade that you could use without changing your whole plan. In this way, you could pay only for the system resources which you really need and you can avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the apps.
