Health Check
In plain terms
A probe verifying that a service is functioning.
Going deeper
A health check is an endpoint or test that reports whether a service is alive and able to serve, used by load balancers and orchestrators. It signals 'am I okay?'
Under the hood
Liveness vs. readiness checks differ; results drive routing, restarts, and traffic decisions.
Examples
/health endpoints, load balancers, Kubernetes probes, uptime monitoring.
Think of it like...
Like a routine pulse check confirming a service is still alive and well.
