If you use a VPS for online and offline apps, you could come across a scenario where they do not function correctly as a result of lack of physical memory. This can happen if you try to run an app which requires more RAM than the amount your package includes, 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 in the event that you get a powerful package, this may happen if you add more applications on the web server in the future, and since it's possible that you shall need only more physical memory, but not higher Processor speeds or more disk space, we offer a RAM upgrade which you may use without changing your whole plan. That way, you can pay only for the system resources that you need and you'll be able to avoid errors on your Internet sites caused by a lack of memory and the inability of the VPS to load the applications.
