If you use a VPS for online and offline applications, you could come across a scenario where they don't work adequately as a result of insufficient physical memory. This may occur if you try to run an app which requires more RAM than the amount your package deal includes, or if 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 plan, this can happen if you add more programs on the web server at some point, and since it's possible that you will require just 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'll be able to pay just for the system resources which you really need and you shall be able to avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the programs.
