In case you use a Virtual Private Server for online and offline applications, you could come across a scenario where they don't perform correctly because of lack of physical memory. This could occur if you try to run an app which requires more RAM than the amount your package comes with, or in the event that you have too many applications and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful package, this may happen if you add more apps on the server in the future, and since it's possible that you'll need simply more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you can use without changing your entire plan. Thus, you can pay only for the system resources that you need and you shall be able to avoid errors on your Internet sites caused by a lack of memory and the inability of the Virtual Private Server to load the apps.
