Quick Answer
Observability lets you ask new questions about your system without deploying new code. Without it, debugging a production issue means guessing. With proper logs, metrics, and traces you can pinpoint which service, which instance, which line of code caused an issue. As systems grow more complex and distributed, observability becomes more critical than ever.
Answer
Observability allows understanding internal system behavior using external signals. It helps detect failures, bottlenecks, and performance issues early. Combines logging, metrics, and distributed tracing for full visibility.
