I’ve joked that if you’re ever confused by a new technology in IT but want to look like you know what you’re talking about, just say it looks like it has potential, but reference how someone tried the exact same thing in the mid-90s. More often than not, whoever you’re talking to will fill in the gaps as you laugh nervously at your own ignorance.
Gina Rosenthal’s post on the history of virtualization and containers gives some of the historical insight to prove that what seems to be new is often simply refinement and reapplication. She rightly points out that the roots of both virtualization and containers both date back to the 70s.
This isn’t to diminish the incredible changes in IT brought on by the two technologies. But Gina rightfully points out that in the brief window of IT history, neither of these concepts is as new as their influence suggests.
And your TIL moment from the post: while the idea underlying what would become containers seems to have originated with FreeBSD Jails, the actual term was coined by Solaris!
Gina Rosenthal comments:
The IT industry isn’t that old, so we don’t have a very long history. Even with the short history, we’ve been able to detect repeatable patterns in technology. The Negroponte Switch (about how wired signals become air-born, and air-born signals become wired), and Moore’s Law (computing power doubles every two years) are two examples.
