In case you use a Virtual Private Server for online and offline programs, you may come across a situation where they don't work adequately due to insufficient physical memory. This may happen if you try to run an app that requires more RAM than the amount your package deal includes, or in the event that you have too many programs 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 applications on the server at some point, and since it's possible that you will require only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade which you may use without changing your whole plan. Thus, you could pay only for the resources that you really need and you'll be able to avoid errors on your sites caused by deficiency of memory and the inability of the VPS to load the applications.
