Why need to modify/edit SSH instead of RDP
SSH is for Linux
Linux instances (like Ubuntu, Amazon Linux) use SSH (Secure Shell) to connect.
You cannot use RDP (Remote Desktop Protocol) for Linux.
So, to log in or modify things, you must edit or use SSH.

Operating system (e.g., Linux, Windows)
Software (like web servers, tools)
System settings
