Understand what ‘additional RAM’ indicates with regard to dedicated servers and Virtual Private Servers and in what ways you can add extra RAM to your server.
Whenever an app is executed on a server, it's loaded into the physical memory. If you run a resource-demanding script, or if you just add more scripts on your sites and you get plenty of visitors, you could encounter a situation where your VPS has insufficient memory to run all the apps and freezes as a result, which means that your websites will stop working correctly and that the website visitors will start seeing error messages. To avoid this sort of a scenario, you can take advantage of the RAM upgrade that we're offering and increase the amount of physical memory for your use without changing the entire plan. In this way, you may pay just for the resources you actually need rather than for additional disk space or higher Central processing unit speeds that you shall not really use, for example. With the upgrade, you'll be able to guarantee the flawless functioning of your sites, which also means a better experience for your site visitors.
Additional RAM in VPS Servers
More physical memory may be added to any one of the Linux VPS web hosting plans we offer, including the top-end ones, consequently your websites will work correctly all of the time. The upgrade is available both on the order page and inside the billing area, so you may add it whenever you require it: before your web server is prepared - in case you know your websites will require additional memory, or after the machine is functioning - in case you notice that the supplied memory is not sufficient for all the sites to function effectively. In the second situation, the amount of RAM which you acquire will be added to the present configuration with no action required on your end and without VPS shutdown or reboot, so there will not be any downtime for your websites. The upgrade is supplied in increments of 128 MB and you'll be able to include as much memory as you need, simply because the physical machines have sufficient resources to permit the virtual servers to be upgraded significantly.
