Containers: Resurrection vs. Reincarnation

This post is to share that I am coining new analogy about containers, cloud and orchestration. Everyone uses Pet vs. Cattle, some use Ant. vs. Elephant. These animal analogies are fine and describe how YOU behave to your machines/containers if something bad happens.

But it's also important to look at things from the other side - what actually happens to the app? How does it feel? How does it perceive world around itself?

Resurrection

In a good old Mode1 world things were simple. Some app died, so you went and resurrected it back to life. Sure, PID was different, but it was the same machine, same environment, same processes around it. Feels like home...

Reincarnation

Then the cloud and container world appeared and people realised they don't want to bring dead things back to life (it might have something to do with all the scary zombie movies, I think). And so in container orchestration you just get rid of things that appear to be dead and then bring new ones to life. And you app is reincarnated instead of resurrected

Resurrection vs. Reincarnation.

Reincarnation is not completely new in IT world - it was already used in MINIX many years ago:). But I am coining this new analogy for containers context. Obviously, it's up to you now to share the wisdom and make sure people know who was the original prophet!

Forget resurrection, reincarnation is a way to go!
