If you use a VPS for online and offline apps, you could come across a situation where they do not function correctly due to insufficient physical memory. This may take place if you try to run an app that requires additional RAM than the amount your plan offers, or in the event that you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even if you get a powerful plan, this may happen if you include more programs on the server in the future, and since it's possible that you shall need simply more physical memory, but not higher Processor speeds or more disk space, our company offers a RAM upgrade which you could use without changing your whole plan. Thus, you can pay just for the resources that you need and you can avoid errors on your websites caused by a lack of memory and the inability of the VPS to load the applications.
