If you use a Virtual Private Server for online and offline applications, you might come across a case where they do not operate properly as a result of insufficient physical memory. This may happen if you try to run a program which requires more RAM than the amount your package offers, or if you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful package, this could happen if you add more programs on the hosting server later on, and since it's possible that you will need simply more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade that you may use without changing your entire plan. 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 VPS to load the applications.
