In the event that you use a Virtual Private Server for online and offline apps, you might come across a case where they do not function correctly due to lack of physical memory. This can occur if you try to run an application which requires more RAM than the amount your plan provides, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even when you get a powerful package, this can happen if you add more programs on the server in the future, and since it is possible that you will need simply more physical memory, but not higher CPU speeds or more disk space, we offer a RAM upgrade which you can use without changing your whole plan. In this way, you may pay just for the system resources that you 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.
