If you use a VPS for online and offline apps, you might come across a situation where they don't function correctly due to insufficient physical memory. This can take place if you try to run an app that requires additional RAM than the amount your package deal provides, or if you have too many applications and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful plan, this can happen if you add more programs on the server at some point, and since it is possible that you will need simply more physical memory, but not higher Processor speeds or more disk space, our company offers a RAM upgrade which you can use without changing your entire plan. This way, you'll be able to pay only for the system resources that you really need and you shall be able to avoid errors on your Internet sites caused by deficiency of memory and the inability of the VPS to load the applications.
