In case you use a VPS for online and offline apps, you might come across a situation where they do not work correctly because of lack of physical memory. This can happen if you try to run an app that requires additional RAM than the amount your plan offers, or if you have too many applications and some of them consume all of the memory, leaving no free RAM for the others. Even if you get a powerful package deal, this could happen if you add more apps on the web server in the future, and since it's possible that you shall need just more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you'll be able to use without changing your entire plan. In this way, you can pay only for the system resources that you need and you can avoid errors on your websites caused by deficiency of memory and the inability of the VPS to load the apps.
