If you use a VPS for online and offline applications, you could come across a scenario where they don't perform correctly because of insufficient physical memory. This can take place if you try to run an app which requires more RAM than the amount your package provides, or in the event that you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful package deal, this could happen if you add more programs on the web server in the future, and since it is possible that you will require just more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you can use without changing your entire plan. In this way, you can pay just for the resources which 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.
