In case you use a Virtual Private Server for online and offline apps, you might come across a situation where they don't perform effectively because of lack of physical memory. This could happen if you try to run an application that requires more RAM than the amount your plan includes, or in the event that you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful plan, this can happen if you include more apps on the hosting server at some point, and since it's possible that you'll need just more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade that you'll be able to use without changing your entire plan. Thus, you may pay just for the system resources that you really need and you'll be able to avoid errors on your sites caused by insufficient memory and the inability of the VPS to load the apps.
