In case you use a VPS for online and offline apps, you might come across a case where they do not operate adequately as a result of lack of physical memory. This may occur if you try to run an app that requires additional RAM than the amount your package 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 when you get a powerful plan, this can happen if you add more apps on the web server in the future, and since it's possible that you will need just more physical memory, but not higher Central processing unit speeds or more disk space, our company offers a RAM upgrade that you'll be able to use without changing your entire plan. Thus, you'll be able to pay just for the system resources that you need and you'll be able to avoid errors on your sites caused by a lack of memory and the inability of the VPS to load the apps.
