As the great Mark Twain once wrote in response to reading his own obituary in May of 1897 , "reports of my death have been greatly exaggerated." Fast forward nearly a hundred years to 1995, and a Finnish computer scientist named Tatu Ylönen created a secure transport protocol known simply as Secure Shell (SSH). What do these things have to do with each other? Nothing, aside from perception.
In its most practical terms, SSH enables users to establish a secure, remote connection with a Linux-based machine via a Command Line Interface (CLI). SSH is the de facto standard for secure server access, and has survived the test of time, despite a significant shift in how infrastructure is operated in the cloud.
