In case you use a VPS for online and offline apps, you could come across a scenario where they don't work effectively as a result of lack of physical memory. This may take place if you try to run an application which requires additional RAM than the amount your package deal comes with, 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 package, this can happen if you include more applications on the hosting server at some point, and since it is possible that you will need only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade that you'll be able to use without changing your entire plan. This way, you'll be able to pay only for the resources that you really need and you shall be able to avoid errors on your sites caused by deficiency of memory and the inability of the Virtual Private Server to load the apps.
