In case you use a Virtual Private Server for online and offline applications, you could come across a case where they don't operate properly as a result of lack of physical memory. This may occur if you try to run a program that requires additional RAM than the amount your package offers, or if you have too many applications 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 may happen if you add more programs on the server later on, and since it's possible that you will require only more physical memory, but not higher CPU speeds or more disk space, we provide a RAM upgrade which you can use without changing your entire plan. Thus, you'll be able to pay only for the system resources that you need and you shall be able to avoid errors on your Internet sites caused by a lack of memory and the inability of the Virtual Private Server to load the apps.
