If you use a VPS for online and offline programs, you may come across a situation where they don't operate adequately due to insufficient physical memory. This could occur if you try to run an application that requires more RAM than the amount your plan offers, or in case you have too many apps and some of them consume all of the memory, leaving no free RAM for the others. Even if you get a powerful package, this could happen if you include more apps on the server at some point, and since it is possible that you will need just more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade which you may use without changing your entire plan. That way, you may pay just for the resources that you need and you'll be able to avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the apps.
