Microservices Development | Multi-Team Coordination
Microservices development requires cross-team coordination. GitScrum tracks service dependencies, API contracts, and deployment orchestration across multiple teams.
5 min read
Microservices architectures require coordinating multiple teams working on independent services with complex interdependencies. GitScrum's cross-project dependencies, API contract tracking, and multi-team visibility features help organizations manage the complexity inherent in distributed systems development.
Microservices Project Challenges
| Challenge | Impact | Solution |
|---|---|---|
| Service dependencies | Blocked work | Dependency mapping |
| API breaking changes | Integration failures | Contract testing |
| Deployment coordination | Outages | Deployment orchestration |
| Cross-team features | Communication overhead | Shared epics |
| Service ownership | Unclear responsibility | Clear ownership model |
Project Organization
MICROSERVICES PROJECT STRUCTURE
Option 1: Project per Service
┌─────────────────────────────────────────────────┐
│ │
│ ┌─────────────┐ ┌─────────────┐ ┌──────────┐ │
│ │ User Service│ │Order Service│ │ Payment │ │
│ │ Project │ │ Project │ │ Service │ │
│ │ │ │ │ │ Project │ │
│ │ Team: Auth │ │ Team: Orders│ │ Team: Pay│ │
│ └─────────────┘ └─────────────┘ └──────────┘ │
│ │
│ Cross-Project Epic: "Mobile Checkout Feature" │
│ └── Tasks distributed to each service project │
│ │
└─────────────────────────────────────────────────┘
Option 2: Project per Domain
┌─────────────────────────────────────────────────┐
│ │
│ ┌─────────────────────────────────────────┐ │
│ │ E-Commerce Platform │ │
│ │ │ │
│ │ Swimlanes by Service: │ │
│ │ ├── User Service │ │
│ │ ├── Order Service │ │
│ │ ├── Payment Service │ │
│ │ └── Notification Service │ │

Dependency Mapping
CROSS-SERVICE DEPENDENCY TRACKING
FEATURE: Add Express Checkout
┌─────────────────────────────────────────────────┐
│ Epic: Express Checkout │
│ │
│ Dependencies (sequence matters): │
│ │
│ Sprint N: │
│ └── [API Design] Payment API contract │
│ └── [API Design] Order API contract │
│ │
│ Sprint N+1: │
│ ├── [User Service] Saved payment methods │
│ └── [Payment Service] Tokenization endpoint │
│ └── Depends on: API Design complete │
│ │
│ Sprint N+2: │
│ ├── [Order Service] Express checkout flow │
│ │ └── Depends on: Payment tokenization │
│ └── [Frontend] Checkout UI │
│ └── Depends on: Order Service API │
│ │
│ Sprint N+3: │
│ └── [Integration] End-to-end testing │
│ └── Depends on: All services complete │
└─────────────────────────────────────────────────┘
API Contract Management
API CONTRACT WORKFLOW
1. DESIGN PHASE
┌─────────────────────────────────────────────────┐
│ Task: Design Payment Tokenization API │
│ │
│ Deliverables: │
│ ☐ OpenAPI spec in shared repo │
│ ☐ Review with consuming teams │
│ ☐ Contract tests defined │
│ ☐ Breaking change assessment │
│ │
│ Reviewers: Order Service, Frontend teams │
└─────────────────────────────────────────────────┘
2. IMPLEMENTATION PHASE
┌─────────────────────────────────────────────────┐
│ Producer Task: Implement Payment API │
│ ├── Implement endpoints per spec │
│ ├── Run contract tests │
│ └── Deploy to staging │
│ │
│ Consumer Task: Integrate with Payment API │
│ ├── Blocked until: API in staging │
│ ├── Implement client │
│ └── Run integration tests │
└─────────────────────────────────────────────────┘
3. BREAKING CHANGE PROTOCOL
┌─────────────────────────────────────────────────┐
│ If breaking change needed: │
│ │
│ Step 1: Announce in #api-changes channel │
│ Step 2: Create migration task for consumers │
│ Step 3: Version the API (v1 → v2) │
│ Step 4: Support both versions during migration │
│ Step 5: Deprecate old version with deadline │
│ Step 6: Remove old version after deadline │
└─────────────────────────────────────────────────┘
Deployment Coordination
MULTI-SERVICE DEPLOYMENT
DEPLOYMENT CHECKLIST FOR FEATURE X:
┌─────────────────────────────────────────────────┐
│ │
│ Pre-Deployment: │
│ ☐ All services passing tests │
│ ☐ Contract tests green │
│ ☐ Database migrations ready │
│ ☐ Feature flags in place │
│ ☐ Rollback procedures documented │
│ │
│ Deployment Order (sequence required): │
│ 1. ☐ Database migrations (all services) │
│ 2. ☐ Payment Service v2.3.0 │
│ 3. ☐ Order Service v1.8.0 │
│ 4. ☐ User Service v3.1.0 │
│ 5. ☐ Frontend v4.2.0 │
│ 6. ☐ Enable feature flag: express-checkout │
│ │
│ Post-Deployment: │
│ ☐ Smoke tests passing │
│ ☐ Monitoring dashboards green │
│ ☐ Error rates normal │
│ ☐ Notify stakeholders │

Best Practices
Anti-Patterns
✗ Services developed in isolation
✗ Breaking API changes without notice
✗ No contract testing
✗ Unclear service ownership
✗ Monolithic deployment of microservices
✗ No cross-team visibility
