Observability Stack

An observability stack is a software architecture designed to monitor, analyze, trace, and understand the behavior of applications, infrastructure, networks, and distributed systems in realtime. By collecting operational data from across a system, observability helps teams detect issues, diagnose failures, optimize performance, and maintain reliability. These architectures are commonly used for cloud platforms, enterprise applications, distributed systems, operational monitoring, and infrastructure management.

The primary goal of an observability stack is to provide continuous visibility into system behavior and operational health.

Typical Architecture

A common observability architecture looks like this:

Applications + Infrastructure
              ↓
Telemetry Collection
              ↓
Metrics + Logs + Traces
              ↓
Storage and Indexing
              ↓
Dashboards + Alerting
              ↓
Incident Response
