In the event that you use a VPS for online and offline applications, you might come across a situation where they do not function effectively because of insufficient physical memory. This could happen if you try to run a program which requires additional RAM than the amount your package deal offers, or in case you have too many apps and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful plan, this can happen if you add more programs on the web server in the future, and since it's possible that you will require only more physical memory, but not higher Central processing unit speeds or more disk space, our company offers a RAM upgrade that you can use without changing your entire plan. In this way, you could pay only for the system resources that you need and you'll be able to avoid errors on your websites caused by insufficient memory and the inability of the VPS to load the applications.
