A control Panel is a GUI (Graphical User Interface) which provides all of the administrative and organisational tools to be able to manage your website(s), or a web hosting account. It’s extremely important that you choose the right control panel to suit your needs as the features/functionality will directly affect your experience as a web hosting reseller or customer.
A control panel makes managing your web hosting service a lot more intuitive and user friendly, providing you with an interface to access administrative tools such as file managers, domain management, DNS editing, SSL renewals, IP configuration, redirecting, account administration, database management, backups, email management website configuration and much more without the hassle of having to primarily use tools such as secure shell direct command-line access or FTP.
In addition to this, they are optimised to work directly with WordPress or similar software making the overall management of your sites far simpler.
