In case you use a Virtual Private Server for online and offline applications, you could come across a scenario where they do not work effectively as a result of insufficient physical memory. This may happen if you try to run an application which requires more RAM than the amount your package offers, or in case you have too many apps and some of them consume all of the memory, leaving no free RAM for the others. Even in the event that you get a powerful package, this could happen if you include more apps on the server at some point, and since it's possible that you'll need simply more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade that you can use without changing your whole plan. This way, you'll be able to pay only for the resources that you need and you shall be able to avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the apps.
