If you use a VPS for online and offline apps, you might come across a situation where they don't operate properly as a result of insufficient physical memory. This can occur if you try to run an application that requires additional RAM than the amount your package deal includes, or in case you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even when you get a powerful package deal, this could happen if you include more applications on the server in the future, and since it is possible that you will require just more physical memory, but not higher Processor speeds or more disk space, our company offers a RAM upgrade that you can use without changing your whole plan. In this way, you could pay just for the resources that you need and you shall be able to avoid errors on your websites caused by deficiency of memory and the inability of the VPS to load the apps.
