Whenever an application is executed on a web server, it is loaded into the physical memory. If you run a resource-demanding script, or if you simply add more scripts on your websites and you get plenty of visitors, you might encounter a scenario where your Virtual Private Server has not enough memory to run all the apps and freezes for that reason, which means your Internet sites will stop working effectively and that the website visitors shall start seeing error messages. To avoid this kind of a scenario, you'll be able to take advantage of the RAM upgrade that we are offering and increase the amount of physical memory for your use without changing the whole plan. In this way, you can pay only for the system resources which you actually need and not for additional disk space or higher Processor speeds that you shall not really use, for example. With the upgrade, you'll be able to guarantee the faultless functioning of your websites, which also means a better experience for your site visitors.
