The more physical memory your VPS has, the more apps you'll be able to run concurrently. Some apps require loads of RAM even if nothing else is running on the hosting server, even though they might not demand high Processor speeds or lots of disk space. In case your web server runs out of memory, it will stop responding and the sites and the offline programs you host on it won't 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 Virtual private server packages, therefore if you discover that your machine is close to the limit, you could make the most of this upgrade without upgrading the whole plan and paying for resources that you won't use. This way, you'll be able to ensure the proper operation of your scripts and stop stressing that your website visitors shall see errors or will not be able to open your websites at all.
Additional RAM in VPS Servers
More physical memory can be added to any of the VPS servers that we offer, including the top-end ones, so your sites shall work flawlessly all of the time. The upgrade is offered both on the order page and in the billing area, so you could add it whenever you need it: before your web server is prepared - provided you know your sites will require more memory, or after the machine is up and running - if you notice that the provided memory isn't enough for all the websites to work correctly. In the second scenario, the amount of RAM you acquire shall be added to the present configuration without any action required on your end and without Virtual Private Server shutdown or restart, so there won't be any downtime for your websites. The upgrade comes in increments of 128 MB and you will be able to add as much memory as you need, simply because the physical hosting servers provide enough resources to enable the virtual servers to be upgraded drastically.
