20 years ago we used simple bash scripts using curl to do rest calls to take one host out of our load balancers, then scp to the host and shut down the app gracefully, and updated the app using scp again, then put it back into the load balancer after testing the host on its own. we had 4 or 5 scripts max, straightforward stuff..

They charge $$$ and you get downtime in this simple scenario ?

I used to work in this world, too. What is described here about EKS/K8s sounds tricky but it is actually pretty simple and quite a lot more standardized than what we all used to do. You have two health checks and using those, the app has total control over whether it’s serving traffic or not and gives the scheduler clear guidance about whether or not to restart it. You build it once (20 loc maybe) and then all your apps work the same way. We just have this in our cookie cutter repo.
