Q. Who needs VPS?
Ans: The short answer is – every system administrator or someone who is serious about their online presence needs it. Some examples of practical applications:
All ranges on the same platform, from low-level shared to medium-power virtual server to powerful dedicated servers – seamless scaling up in the same safe virtual private server.
Put together your existing servers and use more powerful and reliable hardware.
Keep an up-to-date copy of your virtual private server on another server, and start it in seconds in case of failure
Each student gets its own virtual server with root access
Safe experimentation on the machine that runs another services
Install each service in its own freshly created Virtual Private Server, and you will never have to resolve dependency problems.
Keep “snapshots” of the project you are working on and be able to switch back and forth in seconds
Improve network services security
Run each server in its own Virtual Private Server. If the application has a security hole, only this particular virtual private server will be compromised, never the whole system.
