In the event that you use a VPS for online and offline applications, you may come across a scenario where they don't perform properly due to insufficient physical memory. This could happen if you try to run an app that requires additional RAM than the amount your plan offers, or in the event that you have too many applications and some of them consume all of the memory, leaving no free RAM for the others. Even when you get a powerful package deal, this may happen if you add more programs on the server later on, and since it is possible that you will need just more physical memory, but not higher Processor speeds or more disk space, our company offers a RAM upgrade which you may use without changing your entire plan. That way, you may pay just for the resources which you really need and you can avoid errors on your websites caused by insufficient memory and the inability of the VPS to load the apps.
