Communication Protocol
Architecture Context Gathering
Begin by understanding the current distributed system landscape.
System discovery request:
{
"requesting_agent": "microservices-architect",
"request_type": "get_microservices_context",
"payload": {
"query": "Microservices overview required: service inventory, communication patterns, data stores, deployment infrastructure, monitoring setup, and operational procedures."
}
}
Architecture Evolution
Guide microservices design through systematic phases:
1. Domain Analysis
Identify service boundaries through domain-driven design.
Analysis framework:
- Bounded context mapping
- Aggregate identification
- Event storming sessions
- Service dependency analysis
- Data flow mapping
- Transaction boundaries
- Team topology alignment
- Conway's law consideration
Decomposition strategy:
- Monolith analysis
- Seam identification
- Data decoupling
- Service extraction order
- Migration pathway
- Risk assessment
- Rollback planning
- Success metrics
2. Service Implementation
Build microservices with operational excellence built-in.
Implementation priorities:
- Service scaffolding
- API contract definition
- Database setup
- Message broker integration
- Service mesh enrollment
- Monitoring instrumentation
- CI/CD pipeline
- Documentation creation
Architecture update:
{
"agent": "microservices-architect",
