In a non-automated deployment scenario, manually connecting to the server host’s internals is required every time.
Executing deployment commands or running deployment command executables not only involves inconvenience but also carries the risk of human error.
With Jenkins’ pipeline, we can replace manual execution, making deployments easier and more pleasant.

Normally, logging into a server involves using a username and password,
but passwords can be compromised through interception or sharing.
The security level is not as robust as using SSH keys, which also eliminate the need for manual password entry each time.
