If you use a VPS for online and offline applications, you might come across a case where they do not perform effectively due to insufficient physical memory. This could take place if you try to run an app which requires more RAM than the amount your plan comes with, 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 in case you get a powerful plan, this can happen if you include more applications on the hosting server in the future, and since it's possible that you'll need simply more physical memory, but not higher Processor speeds or more disk space, we offer a RAM upgrade that you can use without changing your whole plan. This way, you can pay just for the resources that you really need and you shall be able to avoid errors on your websites caused by insufficient memory and the inability of the Virtual Private Server to load the applications.
