In the event that you use a VPS for online and offline apps, you might come across a situation where they don't operate properly due to insufficient physical memory. This may take place if you try to run a program which requires additional RAM than the amount your plan includes, or in case you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even if you get a powerful plan, this may happen if you include more applications on the web server at some point, and since it's possible that you will need only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade that you may use without changing your whole plan. In this way, you could pay only for the system resources that you need and you'll 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 programs.
