In the event that you use a VPS for online and offline apps, you could come across a scenario where they do not work effectively because of lack of physical memory. This can occur if you try to run a program that requires more RAM than the amount your package provides, or if you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful package deal, this could happen if you add more applications on the web server later on, and since it is possible that you shall need just more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade which you can use without changing your entire plan. That way, you may pay only for the system resources which you really need and you can avoid errors on your sites caused by a lack of memory and the inability of the VPS to load the programs.
