In case you use a VPS for online and offline apps, you may come across a situation where they do not work effectively because of lack of physical memory. This may occur if you try to run a program that requires more RAM than the amount your package includes, 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 may happen if you add more applications on the web server later on, and since it's possible that you shall need simply more physical memory, but not higher Processor speeds or more disk space, we offer a RAM upgrade that you'll be able to use without changing your entire plan. Thus, you can pay just for the resources that you need and you'll be able to avoid errors on your sites caused by a lack of memory and the inability of the VPS to load the applications.
