Microservice team autonomy means freedom to choose technologies: languages, frameworks, databases, infrastructure.

Imagine splitting a large monolith into 10-20 microservices. Each team picks a stack different from the original system — and different from each other.

This leads to:

• new folder structures
• new code style conventions
• new linting rules
• new test harnesses
• new database schemas
• new CI/CD pipelines
• new infrastructure definitions
• new monitoring and alerting setups

And this can turn very problematic:

• Most of these decisions require thorough analysis with long discussions — even within a single team.
• Engineers face a steep learning curve as the whole tech stack differs from the one they are used to.
• API boundaries become harder to reason about when teams mix REST, GraphQL, RPC, and custom protocols.
• Infrastructure complexity explodes — the teams might start spending more time on configuration than on writing new features!

Microservices aim to enable independent teams and faster delivery — but not every decision benefits from decentralization.

I’m writing a full series on microservice architecture — from base definitions to hands-on topics like testing, deployment, and observability.
