RAM, or Random Access Memory, is a space used by your server for computing operations. RAM influences directly on the VPS functionality. Hence, a common concern among VPS users is how much RAM they need. This is not an easy question. The answer varies depending on the application for which the VPS is used. The expected traffic plays also a role.
The programs installed and the configurations may be ideal for one user, but may not work for a different one. Hence, think whether you need one or more services running on your Russia VPS. Each type of service and application has a particular RAM requirement. For instance, for a site using WordPress VPS, 256 MB of RAM would be necessary. And that is the minimum t work acceptably.
RAM-hungry applications like cPanel need at least 1 GB of RAM. This amount of RAM is exclusively for the cPanel software. Hence, you will need to add some RAM overhead. And in general, you should not work with a restricted amount of RAM. Imagine if your website becomes extremely popular. The least you want is seeing your website crash because of the lack of computational resources.
Moreover, adding RAM will always increase the speed of your VPS. If the RAM is not enough for a service, the server starts using the hard disk to compensate. This is called ‘swapping.’ The result is a noticeably slow VPS. Hence, make sure you have enough RAM for all the processes that will be running on the VPS.
