The more physical memory your VPS has, the more applications you'll be able to run simultaneously. Some apps require a lot of RAM even if nothing else is running on the web server, even though they might not demand high Processor speeds or loads of disk space. In case your web server runs out of memory, it will stop responding and the Internet sites and the offline apps that you host on it won't work adequately, 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 packages, therefore if you notice that your web server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole package and paying for system resources which you won't use. This way, you can guarantee the proper operation of your scripts and stop concerning that your website visitors will see errors or will be unable to open your websites at all.
