If you use a VPS for online and offline apps, you could come across a scenario where they do not function adequately as a result of insufficient physical memory. This could take place if you try to run an application which requires additional RAM than the amount your package comes with, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful package deal, this can happen if you include more apps on the web server in the future, and since it is possible that you shall need only more physical memory, but not higher Processor speeds or more disk space, our company offers a RAM upgrade which you could use without changing your entire plan. This way, you can pay just for the system resources that you need and you'll be able to avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the applications.
