If you use a VPS for online and offline programs, you could come across a scenario where they do not operate effectively due to lack of physical memory. This can happen if you try to run an app that requires more RAM than the amount your plan 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 case you get a powerful plan, this can happen if you include more apps on the hosting server at some point, and since it is possible that you'll need only more physical memory, but not higher Central processing unit speeds or more disk space, our company offers a RAM upgrade that you could use without changing your entire plan. In this way, you could pay only for the 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 VPS to load the apps.
