If you use a VPS for online and offline apps, you could come across a case where they do not operate properly as a result of lack of physical memory. This may occur if you try to run an application that requires additional 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 the event that you get a powerful package deal, this could happen if you include more programs on the web server later on, and since it's possible that you will need just more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade which you'll be able to use without changing your whole plan. This way, you'll be able to pay just for the system resources that you really need and you shall be able to avoid errors on your websites caused by a lack of memory and the inability of the VPS to load the apps.
