In case you use a VPS for online and offline applications, you could come across a situation where they don't function adequately as a result of insufficient physical memory. This could happen if you try to run an app which requires more RAM than the amount your plan offers, or in the event that you have too many apps and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful package, this can happen if you add more programs on the server in the future, and since it's possible that you shall need just more physical memory, but not higher Processor speeds or more disk space, we provide a RAM upgrade that you may use without changing your entire plan. In this way, you'll be able to pay just for the system resources that you really need and you can avoid errors on your websites caused by deficiency of memory and the inability of the VPS to load the applications.
