Hands On System Design with "Distributed Systems Implementation - 254-Lesson’s curriculum"

Today, we're building compatibility layers - sophisticated adapters that can read logs from syslog (the old-school Unix standard) and journald (systemd's modern approach), then translate them into our unified format. This is where the rubber meets the road in production systems, because real infrastructure never speaks just one logging language.

The Core Concept: Think Like a Universal Translator

A compatibility layer works like a smart translator that understands multiple "languages" (log formats) and converts them into a common "language" (standardized format) that your processing pipeline understands. Yesterday we built our schema registry - think of it as our translation dictionary. Today we're building the actual translators.
