Reliability engineering stopped scaling

Systems got more complex. Monitoring produced more data. But understanding didn't keep up.

Monolith App

Microservices

10xmore complex

Your systems evolved. Your tools didn't.

Hours to find root cause

Same failures repeat

Seniors become bottlenecks

Every deploy feels risky

Monitoring shows symptoms, not causes

The gap between what happened and why it happened

What Monitoring Shows

Symptoms

CPU Usage

spike at 2:15 AM

Error Rate

increased 45%

Latency

degraded to 2.3s

The Gap

What You Need

Root Causes

Change

Deploy #1847 at 2:13 AM

Propagation

API → Database → Cache

Root Cause

Connection pool exhausted

Bridging this gap requires connecting symptoms to their actual causes

What changes when you prevent failures

Reactive Approach

→Hours to find root cause

→Same failures repeat

→Deploy anxiety

→Constant firefighting

Prevention Approach

→Root cause in minutes

→Problems caught early

→Confident deploys

→Predictable systems

Stop asking who can fix this. Start preventing it.
