In the event that you use a VPS for online and offline programs, you could come across a situation where they don't operate effectively because of lack of physical memory. This may occur if you try to run a program which requires more RAM than the amount your package deal offers, or if you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even in the event that you get a powerful plan, this can happen if you add more apps on the server in the future, and since it is possible that you will require simply more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade which you can use without changing your entire plan. This way, you'll be able to pay only for the system 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 VPS to load the apps.
