The more physical memory your VPS has, the more applications you'll be able to run all at once. Some programs require lots of RAM even when nothing else is running on the hosting server, even though they may not demand high CPU speeds or loads of disk space. If your server runs out of memory, it'll stop responding and the Internet sites and the offline applications that you host on it will not function effectively, 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, thus if you notice that your web server is close to the limit, you'll be able to take advantage of this upgrade without upgrading the whole plan and paying for resources which you won't use. This way, you could ensure the proper functioning of your scripts and stop stressing that your website visitors will see errors or will not be able to open your sites at all.
