RAM, that refers to Random Access Memory, is a computer storage media that is accessed considerably faster than a hard drive, simply because the info can be read randomly, skipping the bytes before the needed info is reached. On a server, the RAM is employed to load scripts and web apps when they are executed, so the more RAM you can use, the more apps you'll be able to run simultaneously and the more people will be able to browse your sites without effect on the site’s/server’s functionality. Unlike a disk drive, however, the RAM is employed for short-term storage purposes, as the info is lost as soon as the power is shut off. In case you use a shared web hosting account, the physical memory which your scripts may use may be limited and can change based on what the some other clients on the same hosting server use. With a virtual or a dedicated hosting server, however, you will have a guaranteed amount of RAM that won't be used by others even when you do not use it at a particular time.
Guaranteed RAM in VPS Servers
The physical memory which you will get with each VPS server which we offer you is guaranteed and shall be readily available all of the time even if you don't use all of it for a long stretch of time. Each VPS account offers fixed system resources and runs in an isolated container apart from all the other accounts on the physical server, so even if some account starts running out of memory, we won't allocate some of your memory to that account. Also we never distribute the whole physical memory on the hardware node among the virtual accounts set up on it, as a way to guarantee that it won't run out of memory. Thus, there will always be free RAM if you want to upgrade your package and we guarantee the flawless operation of the physical machine.
