A control panel is necessary when you manage servers and hosting services. It enables users to perform and automate tasks more efficiently, saving time and effort. The control panel also provides an overview of the server status and the performance of the hosting services, making it easy to identify and resolve any issues. It can also help manage multiple websites and domains, set up email accounts, and manage files and databases. Overall, a control panel can simplify and streamline management of servers and hosting services, making it a valuable resource for any user who works with these services. If you are well acquainted with all server functions and would rather spend a little more time on server management than invest in a control panel, you can do without it.
