In the event that you use a VPS for online and offline apps, you could come across a situation where they do not function adequately as a result of insufficient physical memory. This may happen if you try to run an application that requires additional RAM than the amount your package deal provides, 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 case you get a powerful plan, this could happen if you include more programs on the web server in the future, and since it's possible that you will require only more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you can use without changing your whole plan. This way, you'll be able to pay only for the resources that you really need and you can avoid errors on your websites caused by insufficient memory and the inability of the VPS to load the apps.
