If you use a Virtual Private Server for online and offline apps, you might come across a case where they don't operate effectively as a result of insufficient physical memory. This could occur if you try to run an app that requires additional RAM than the amount your package deal offers, or in case you have too many apps and some of them consume all of the memory, leaving no free RAM for the others. Even if you get a powerful plan, this could happen if you add more applications on the web server in the future, and since it is possible that you'll need just more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade that you'll be able to use without changing your entire plan. In this way, you could pay just for the system resources that you need and you can avoid errors on your websites caused by deficiency of memory and the inability of the Virtual Private Server to load the applications.
