Tiny Checks, Massive Impact

Straight to the point — whenever I build a system, the very first thing I implement is a health check for all critical infrastructure components.

I ping the database. I ping Redis. Just simple, lightweight checks.

They may seem minor, but skipping them can lead to serious consequences. At best, you get a false sense that everything is working fine. At worst, the system enters an inconsistent state that's painful to debug and even harder to recover from.
