The more physical memory your Virtual Private Server has, the more apps you shall be able to run at the same time. Some applications require plenty of RAM even if nothing else is running on the hosting server, even though they may not require high Processor speeds or lots of disk space. In case your server runs out of memory, it will stop responding and the websites and the offline programs that you host on it will not function properly, as their software components shall not load since there won't be any free memory. In this light, we offer a RAM upgrade for our VPS solutions, thus if you detect that your hosting server is close to the limit, you can make the most of this upgrade without upgrading the whole plan and paying for resources that you will not use. This way, you'll be able to ensure the proper operation of your scripts and stop stressing that your site visitors will see errors or won't be able to open your websites at all.
