How One CTO Uses Chaos Engineering to Build Resilient Systems
In this episode of Tech Leadership with Fexingo, Lucas and Luna explore chaos engineering with a concrete case: how a CTO at a mid-sized e-commerce platform used controlled fault injection to uncover a critical database failover bug before Black Friday. They walk through the specific experiment design—shutting down one of three Cassandra nodes during low traffic—and the surprising finding that the application's connection pool didn't retry, causing a 12-second timeout cascade. Lucas explains the principles behind chaos engineering (steady-state hypothesis, blast radius, automate experiments)…
