If you use a VPS for online and offline apps, you might come across a situation where they don't perform effectively due to insufficient physical memory. This could happen if you try to run a program that requires more 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 in case you get a powerful package deal, this may happen if you include more programs on the server at some point, and since it's possible that you will need simply more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade that you'll be able to use without changing your whole plan. That way, you may pay only for the system resources that you really need and you'll be able to avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the applications.
