If you use a VPS for online and offline apps, you may come across a situation where they do not operate adequately due to lack of physical memory. This could happen if you try to run an application which requires additional RAM than the amount your package offers, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful package, this could happen if you include more applications on the web server in the future, and since it's possible that you will require just more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade which you may use without changing your whole plan. Thus, you can pay only for the system resources that you really need and you can avoid errors on your Internet sites caused by a lack of memory and the inability of the VPS to load the programs.
