A walkthrough of taking a monolithic Java backend through the scaling journey — what we changed at each stage, what broke, and the concrete decisions that moved the needle when traffic grew 50×.
How to actually know what your distributed system is doing in production — the three signals, the tools that compose them, and the operational discipline that turns telemetry from cost center into debugging superpower.
