In the event that you use a Virtual Private Server for online and offline apps, you may come across a case where they do not work properly because of insufficient physical memory. This can happen if you try to run an app that requires more RAM than the amount your package provides, or in the event that you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful package, this can happen if you add more applications on the web server at some point, and since it is possible that you will need simply 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. In this way, you could pay only for the resources which you really need and you'll be able to avoid errors on your sites caused by a lack of memory and the inability of the Virtual Private Server to load the applications.
