Secure Shell (SSH) is a protocol that allows secure and encrypted communication between a client and a server over a network. SSH can be used to log in to a remote Linux server that is hosted in a public cloud, as well as to execute commands, transfer files, or tunnel other protocols. SSH uses public-key cryptography to authenticate the client and the server, and to encrypt the data exchanged between them. SSH is widely supported by most Linux distributions and cloud providers, and it can be accessed by various tools, such as PuTTY, OpenSSH, or WinSCP. SSH is more secure and reliable than other protocols, such as RDP, VNC, or Telnet, which may not support encryption, authentication, or compression. References: CompTIA Cloud Essentials+ Certification Exam Objectives1, CompTIA Cloud Essentials+ Study Guide, Chapter 6: Cloud Connectivity and Load Balancing2, How To Use The Remote Desktop Protocol To Connect To A Linux Server2
