In case you use a Virtual Private Server for online and offline applications, you might come across a scenario where they don't perform correctly because of lack of physical memory. This may occur if you try to run an app which requires more RAM than the amount your package includes, 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 when you get a powerful plan, this can happen if you add more applications on the server later on, and since it is possible that you will need simply more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade that you can use without changing your whole plan. In this way, you could pay only for the system resources that you need and you can avoid errors on your sites caused by deficiency of memory and the inability of the Virtual Private Server to load the programs.
