In case you use a Virtual Private Server for online and offline applications, you might come across a case where they don't function effectively because of lack of physical memory. This can happen if you try to run an app that requires additional RAM than the amount your package deal comes with, or if you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful package, this can happen if you add more apps on the web server at some point, and since it is possible that you will need simply more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you'll be able to use without changing your entire plan. This way, you may pay just for the resources that you really need and you shall be able to avoid errors on your sites caused by deficiency of memory and the inability of the VPS to load the applications.
