The more physical memory your VPS has, the more apps you'll be able to run simultaneously. Some apps require lots of RAM even when nothing else is running on the server, even though they may not demand high CPU speeds or a lot of disk space. In case your server runs out of memory, it shall stop responding and the sites and the offline apps which you host on it shall not function properly, as their software components won't load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, therefore if you discover that your hosting server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole plan and paying for system resources that you will not use. This way, you can guarantee the proper functioning of your scripts and stop stressing that your site visitors shall see errors or won't be able to open your sites at all.
Additional RAM in VPS
Additional physical memory could be added to any of the Linux VPS services
that we offer, including the top-end ones, so your Internet sites will function flawlessly all of the time. The upgrade is offered both on the order page and in the billing area, so you may add it anytime you require it: before your web server is prepared - in case you know your websites will require more memory, or after the machine is up and running - if you notice that the default memory is not sufficient for all the sites to operate adequately. In the second situation, the amount of RAM which you order shall be added to the current configuration without any activity required on your end and without any VPS shutdown or reboot, so there won't be any downtime for your Internet sites. The upgrade comes in increments of 128 MB and you shall be able to add as much memory as you require, since the physical machines offer enough system resources to allow the virtual servers to be upgraded drastically.
