In case you use a Virtual Private Server for online and offline apps, you could come across a scenario where they do not work effectively because of lack of physical memory. This may occur if you try to run an app that requires additional RAM than the amount your package deal comes with, or in case you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even when you get a powerful plan, this can happen if you include more programs on the server in the future, and since it's possible that you shall need just more physical memory, but not higher Central processing unit speeds or more disk space, we provide a RAM upgrade that you can use without changing your entire plan. Thus, you can pay just for the resources that you need and you can avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the applications.
