Benefits of Grouping or Consolidating Microservices
1. Reduced Complexity
Fewer moving parts = easier to understand the system.
Less overhead managing inter-service communication, contracts, retries, circuit breakers, etc.
Simplifies onboarding for new developers.
🔧 Instead of juggling 20 tiny services, you might just need to care about 5 cohesive ones.
2. Easier Deployment
Fewer pipelines, artifacts, and deployment steps.
Less orchestration overhead in CI/CD.
Easier versioning and coordination.
💡 If multiple services always deploy together, just deploy them as one.
3. Better Performance
Reduced network calls between services = lower latency.
Less chance of cascading failures due to flaky inter-service dependencies.
Easier transaction handling (fewer distributed transactions or eventual consistency headaches).
4. Simplified Data Management
Shared models and schemas are easier to maintain.
No need to synchronize data across service boundaries.
Avoids duplication of data and logic.
5. Less Operational Overhead
Fewer services = fewer logs, alerts, configs, metrics, and dashboards to maintain.
Reduced need for infrastructure (containers, service discovery, API gateways).
6. Cleaner Domain Boundaries
Often when services are too fine-grained, they don’t reflect real business capabilities.
Grouping helps align services with actual domain contexts (DDD style).
7. Improved Developer Velocity
Changes are easier to make without worrying about breaking downstream services.
Less boilerplate and duplicated effort.
⚠️ But Be Careful…
You don’t want to swing too far and end up with a mini-monolith. The key is to consolidate logically, based on:
Business capability
Deployment and change patterns
Data ownership
