We've seen a tremendous transition in the architecture of our systems over the years, from basic, linear systems to increasingly sophisticated, non-linear systems. We've moved away from monolithic programs, where a single person could comprehend the entire operation of a system, and toward a distributed world dominated by a microservices design.

Incident response has been the cornerstone of reliability for decades. From digging in the server logs to navigating modern observability dashboards, responding quickly to incidents and outages is a big part of minimizing downtime. And it should be! When something breaks, your team should move as quickly as possible to address and repair the problem.
