The more physical memory your Virtual Private Server has, the more programs you shall be able to run simultaneously. Some apps require lots of RAM even when nothing else is running on the web server, even though they may not demand high Processor speeds or a lot of disk space. In the event your server runs out of memory, it will stop responding and the websites and the offline programs which you host on it will not work properly, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our VPS solutions, so if you detect that your web server is close to the limit, you may take full advantage of this upgrade without upgrading the whole package and paying for system resources that you will not use. That way, you can guarantee the proper operation of your scripts and stop worrying that your site visitors shall see errors or won't be able to open your sites at all.
