Choose Between Microservices and Modular Monolith for a Scale-Up

FreeVerified credential3 weeksAdvanced

Overview

What this challenge is about.

Audit a Rails codebase and survey squads to choose between microservices and modular monolith. Deliver a decision memo and 90-day plan. Get a verifiable certificate.

The scenario

The scale-up (around 700 dental practices, EUR-only billing) cannot afford an 18-month microservices migration that doesn't pay back — and cannot afford to be paralyzed by a 'should we?' debate either.

The Brief

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

Recommend monolith vs modular monolith vs microservices for a 50-person engineering org with evidence from the codebase, team topology, and scaling pressures.

Earning criteria — what you'll demonstrate

  • Use git co-change analysis to find bounded contexts in a Rails monolith
  • Apply Team Topologies (Stream-aligned, Platform, Enabling, Complicated-Subsystem) to architecture decisions
  • Compare microservices vs modular monolith vs status quo with evidence
  • Write a decision memo that survives engineering scrutiny and gets sign-off

Program Fit
