What you’ll learn

Six levels, from one codebase to agent-ready systems

Every software team hits the same fork sooner or later: one big codebase, or dozens of small services? The guide walks through the decision with one running example, Rutavo, a logistics startup.

LEVEL 1

The monolith

Why one codebase, one deploy and one database is a gift while you are small.

LEVEL 2

Where it hurts

The four pains that show up first, plus a warning-signs checklist for your team.

LEVEL 3

Microservices, done right

The three rules of a real service: own data, clear API, own schedule.

LEVEL 4

The bill nobody puts on the slide

Seven operational costs you must be ready to pay before you split anything.

LEVEL 5

How to choose

Start modular, split only for a real pain, and peel off one service at a time.

LEVEL 6

The AI angle

What makes your system safe and usable for AI agents, with or without microservices.
