If you use a VPS for online and offline programs, you could come across a scenario where they don't operate adequately due to lack of physical memory. This could occur if you try to run a program which requires more RAM than the amount your package deal comes with, or in the event that you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful package, this may happen if you add more applications on the web server later on, and since it is possible that you shall need simply more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade that you can use without changing your whole plan. In this way, you can pay only for the system resources which you really need and you'll be able to avoid errors on your websites caused by a lack of memory and the inability of the Virtual Private Server to load the programs.
