In the event that you use a Virtual Private Server for online and offline programs, you could come across a scenario where they don't work properly as a result of lack of physical memory. This may take place if you try to run an application which requires more RAM than the amount your package provides, or in case you have too many applications and some of them consume all of the memory, leaving no free RAM for the others. Even in the event that you get a powerful package, this may happen if you include more applications on the web server at some point, and since it is possible that you shall need only more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade which you could use without changing your whole plan. Thus, you'll be able to pay only for the system resources that you 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 apps.
