I'm curious about this trivial automation. Let's say the new OS LTS version no longer includes nginx, because it was replaced by a new product with different config. How does the automation figure out what the new server package is and migrate your old Nginx config to the new format?

I agree with Node.js version deprecations being a huge problem and personally advocate for an evergreen WebAssembly platform for running apps. Apps should run forever even if the underlying platform completely changes, and only require updating if the app itself contains something that needs updating.

The answer is to write your server in portable C++, and just rebuild it for whatever new OS you're dealing with.

The speed. Imagine the performance. There are plenty of mature C++ web server frameworks, it's really not difficult. If you're afraid of C++, you could choose something else. Rust if you're insane, or golang if you're insane but in a different way.

Anyway. Nginx is not going away, so the argument is a bit silly. "What if js went away". Same thing.

If an LTS of an OS replaced nginx with something else, a. it would be announced with great fanfare months in advance b. if you don’t want to do that, add apt / yum / zypper install nginx to your Ansible task, or whatever you’re using.

The things that you just described are not automation, but human activities needed to tackle the new situation by following news and creating new automation. Which kind of proves my point that you cannot prepare for every unexpected situation before it actually happens. Except maybe with AI in the future.

When AWS announces that they’re EOL’ing the Python or NodeJS version in your Lambda, or the version of your RDS cluster, etc. you also are required to take human action. And in fact, at any appreciable scale, you likely want that behavior, so you can control the date and time of the switch, because “zero downtime” is rarely zero downtime.

Yes, and like I mentioned in another comment, I consider this a major painpoint and problem with Node.js based applications. I have high hopes that eventually there will be an "evergreen" WebAssembly based Lambda function runtime.
