In case you use a Virtual Private Server for online and offline programs, you could come across a scenario where they don't perform effectively because of lack of physical memory. This could occur if you try to run an application which requires additional RAM than the amount your package includes, or in the event that you have too many applications 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 deal, this may happen if you add more apps on the web server in the future, and since it is possible that you will require just more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade that you may use without changing your entire plan. In this way, you could pay only for the resources which you really need and you can avoid errors on your websites caused by a lack of memory and the inability of the VPS to load the programs.
