A VPS is a slice of a physical server, isolated by virtualisation, that you control like a machine of your own: you get root access, install what you want, and host as many sites as its CPU, memory and disk allow.
With that freedom comes responsibility — unlike shared hosting, you are the administrator: updates, security, backups and monitoring are your job. That is exactly the gap monitoring tools fill: watching CPU, memory, services, mail and security around the clock so problems surface before customers notice.
Frequently asked questions
What is the difference between a VPS and shared hosting?
On shared hosting the provider administers the server and you get a folder. On a VPS you get the whole (virtual) machine — root access, your own services, and full responsibility for keeping them healthy.
Do I need to install monitoring software on the VPS itself?
Not necessarily. Agentless tools like VpsMonitor.Pro connect over SSH and read everything remotely — nothing is installed server-side.
