If you use a VPS for online and offline applications, you may come across a situation where they do not perform adequately as a result of lack of physical memory. This may take place if you try to run an application which requires more RAM than the amount your package deal includes, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even in case you get a powerful plan, this could happen if you include more applications on the web server at some point, and since it is possible that you shall need just more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade which you could use without changing your entire plan. This way, you may pay just for the resources which you really need and you'll be able to avoid errors on your websites caused by a lack of memory and the inability of the VPS to load the apps.
