In the event that you use a VPS for online and offline programs, you might come across a situation where they do not function effectively because of insufficient physical memory. This could take place if you try to run a program that requires more RAM than the amount your package offers, or in case you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful plan, this could happen if you add more programs on the server in the future, and since it's possible that you will require simply more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you could use without changing your whole plan. Thus, you could pay only for the system resources which 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.
