Hackers, what do we do when sometimes things go wrong? "Undo" is sometimes a good approach.
Let's talk about deployment rollback! 💬
What tools do you use for rollback handling?
Is this a real question?
If you have a cd system, you click the deployment from before and click deploy
If you manually deploy and have version control - git, you pick a version before and deploy
If you hack everything manually you just roll fwd with fixes
In bigger ent. You can have smoke tests to auto rollback or not roll fwd the traffic at all
