Microservices rules: what good looks like

The 11 microservices rules are a great checklist that engineering leaders can use to assess the state of their organization, its delivery practices and its application’s architecture and keep their migration to microservices on track.

Why microservices rules

The microservice architecture has become increasingly popular over the past decade. Its key benefits include significantly improving the developer experience and accelerating software delivery. Sadly, however, microservices have often been widely misunderstood and used inappropriately. As a result, many organizations have struggled to benefit from their adoption. I’ve had numerous conversations where developers have complained that their new microservices-based applications are difficult to change. They have very quickly created an unmaintainable legacy application. To prevent this from happening, I’ve defined 11 development and architecture rules (a.k.a. best practices).

The 11 rules

Here are the rules with links to detailed explanations:

1. Practice continuous delivery/deployment
2. Implement fast, automated deployment pipelines
3. Apply Team Topologies
4. Provide a great developer experience (DevEx)
5. Use a deliberative design process
6. Design independently deployable services
7. Design loosely coupled services
8. Design testable services
9. Develop observable services
10. Big/risky change => smaller/safer and (ideally easily) reversible changes - part 1 - incremental architecture modernization, part 2 - continuous deployment, part 3 - canary releases, part 4 - incrementally migrating users, part 5 - smaller user stories
11. Track and improve software metrics and KPIs
