The more physical memory your Virtual Private Server has, the more programs you'll be able to run simultaneously. Some apps require plenty of RAM even if nothing else is running on the server, even though they might not demand high Processor speeds or plenty of disk space. If your server runs out of memory, it shall stop responding and the sites and the offline apps which you host on it will not work effectively, as their software components will not load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server solutions, so if you notice that your machine is close to the limit, you may make the most of this upgrade without upgrading the whole plan and paying for resources that you will not use. That way, you can ensure the proper functioning of your scripts and stop concerning that your site visitors will see errors or won't be able to open your Internet sites at all.
