In the event that you use a VPS for online and offline applications, you might come across a case where they do not perform correctly due to lack of physical memory. This may happen if you try to run a program that requires additional RAM than the amount your package deal includes, or in case 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 package deal, 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 Central processing unit speeds or more disk space, we provide a RAM upgrade which you can use without changing your whole plan. This way, you'll be able to pay just for the system resources which you really need and you'll be able to avoid errors on your sites caused by deficiency of memory and the inability of the VPS to load the applications.
