The more physical memory your Virtual Private Server has, the more apps you shall be able to run all at once. Some applications require lots of RAM even when nothing else is running on the server, even though they might not require high Processor speeds or a lot of disk space. If your server runs out of memory, it'll stop responding and the websites and the offline applications which you host on it won't 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 Virtual private server packages, so if you discover that your server is close to the limit, you can make the most of this upgrade without upgrading the whole package and paying for resources which you won't use. That way, you could ensure the proper functioning of your scripts and stop concerning that your visitors will see errors or won't be able to open your websites at all.
