If you use a Virtual Private Server for online and offline programs, you might come across a scenario where they don't operate properly because of lack of physical memory. This could happen if you try to run an app which requires more RAM than the amount your package provides, or in the event that you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful plan, this can happen if you include more programs on the server at some point, and since it's possible that you shall need only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade that you could use without changing your entire plan. In this way, you may pay only for the system resources that you need and you'll be able to avoid errors on your websites caused by a lack of memory and the inability of the Virtual Private Server to load the programs.
