In case you use a Virtual Private Server for online and offline applications, you could come across a scenario where they do not function effectively as a result of insufficient physical memory. This can occur if you try to run a program that requires more RAM than the amount your plan provides, or in case you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful plan, this can happen if you include more applications on the server at some point, and since it's possible that you will require just more physical memory, but not higher Central processing unit speeds or more disk space, we provide a RAM upgrade that you'll be able to use without changing your whole plan. Thus, you could pay only for the resources which you really need and you can avoid errors on your sites caused by insufficient memory and the inability of the Virtual Private Server to load the applications.
