In the event that you use a Virtual Private Server for online and offline programs, you may come across a case where they don't perform properly because of lack of physical memory. This could take place if you try to run an application which requires additional RAM than the amount your package offers, or in case you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even if you get a powerful plan, this could 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 CPU speeds or more disk space, our company offers a RAM upgrade which you'll be able to use without changing your entire plan. In this way, you can pay just for the resources that you need and you'll be able to avoid errors on your Internet sites caused by deficiency of memory and the inability of the VPS to load the apps.
