In the event that you use a VPS for online and offline apps, you might come across a scenario where they don't perform effectively as a result of lack of physical memory. This could take place if you try to run an app that requires additional RAM than the amount your package comes with, 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 when you get a powerful plan, this could happen if you add more applications on the server at some point, and since it is possible that you'll need only more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade which you may use without changing your whole plan. That way, you can pay just for the resources which you really need and you'll be able to avoid errors on your sites caused by a lack of memory and the inability of the Virtual Private Server to load the programs.
