Master the discipline of separating configuration from code for flexibility and safety.

Separate read and write models to optimize for different access patterns and enable flexible data transformation.

Scale data storage horizontally by distributing data across multiple databases and replicas.

Isolate service data with dedicated databases to maintain independence and prevent tight coupling.

Services that call each other synchronously in sequence, creating tight coupling and monolith behavior.

Store the complete history of changes as immutable events rather than storing only the current state.

Use feature flags to decouple deployment from release and enable safer experimentation.

Collect and analyze logs with structure and correlation IDs to understand system behavior.

Measure system behavior with metrics using RED and USE methods to identify performance issues.

Services too small to be useful, requiring many inter-service calls and creating excessive complexity.

Ensure reliable event publishing and delivery with outbox, inbox, and CDC patterns.

Every inter-service communication is synchronous, creating blocking dependencies and reducing resilience.

Evolve data schemas safely without breaking clients as systems change over time.

Multiple services accessing the same database directly, creating coupling and preventing independence.
