In the event that you use a Virtual Private Server for online and offline apps, you might come across a situation where they don't function properly due to insufficient physical memory. This could take place if you try to run an application which requires additional RAM than the amount your plan offers, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even when you get a powerful package, this can happen if you add more applications on the server at some point, and since it is possible that you will require only more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade that you could use without changing your entire plan. Thus, you could pay only for the resources that you really need and you'll be able to avoid errors on your Internet sites caused by insufficient memory and the inability of the VPS to load the applications.
