In case you use a VPS for online and offline apps, you may come across a situation where they don't function properly because of lack of physical memory. This could take place if you try to run a program which requires additional RAM than the amount your package deal comes with, 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 case you get a powerful plan, this could happen if you add more programs on the web server at some point, and since it's possible that you will need just 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. This way, you could pay just 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 VPS to load the apps.
