Migrate a 600K-LOC Monolith to a Modular Monolith

FreeVerified credential4 weeksExpert

Overview

What this challenge is about.

Run static dependency analysis, lead a boundary workshop, migrate 2 modules, and author a 12-month migration plan. Earn a verifiable certificate.

The scenario

The insurtech (Series-C at EUR 140M raised, regulated under BaFin and Solvency II) has had 3 failed microservices proposals — leadership wants modular monolith first as a safer step.

The Brief

What you'll do, and what you'll demonstrate.

Design module boundaries from dependency analysis, ship a 2-module Packwerk pilot, and plan a 12-month modular-monolith migration for a 600K-LOC Rails codebase.

Earning criteria — what you'll demonstrate

  • Surface implicit module boundaries from static dependency analysis
  • Design explicit module APIs in a Packwerk-style modular monolith
  • Plan a multi-year migration with leading + lagging KPIs
  • Sequence pilot vs full-migration work to maintain delivery throughput
