What They Don’t Teach About Infra Engineering

You can build a web app in a day. and then you can deploy it to the cloud with a script someone else wrote.

That’s not the hard part in my opinion

The hard part starts when it breaks in prod and no one knows why that happened.
no logs, no alerts, just a broken system and a Slack channel full of guesses.

Why this happens

Because most devs never learn how real systems behave.

So when shit hits the fan people panic, start tailing logs, restart pods, pray, and hope it goes away.

This is what happens when you never learned to think in systems.

Infra engineering is not just knowing tools

It's not just “learn Docker” or “deploy on Kubernetes.”

It's:

• knowing when your system is lying to you

• knowing what’s going to break under load before it does

• writing alerts that actually catch the problem, not just spam you at 3am

• tracing a user flow across 3 services, 2 queues, and a job that failed silently

• having rollback plans that don’t involve “hope”

Most devs don’t get taught this. They only learn it after something goes down.
