In case you use a Virtual Private Server for online and offline apps, you might come across a case where they don't work adequately because of lack of physical memory. This can occur if you try to run a program which requires additional RAM than the amount your package includes, or if you have too many applications 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, this could happen if you include more apps on the web server later on, and since it is possible that you will require simply more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you could use without changing your entire plan. That way, you may 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.
