🏗️ Architecture Best Practices

Pattern	Description	Implementation	Benefits
Circuit Breaker	Prevent cascading failures	Hystrix, Resilience4j	System resilience, graceful degradation
Event Sourcing	Store events instead of current state	Event store, replay capability	Audit trail, time travel debugging
CQRS	Separate read/write models	Command/Query segregation	Optimized performance, scalability
Saga Pattern	Distributed transaction management	Choreography/Orchestration	Data consistency, error recovery

🔧 Troubleshooting Guide

❗ Common Issues & Solutions

Issue	Symptoms	Possible Causes	Solutions
Order Processing Delays	High processing times, queue backlog	Database contention, inventory service down	Scale services, optimize queries, check dependencies
API Timeouts	HTTP 504 errors, slow responses	Network latency, resource constraints	Increase timeouts, scale horizontally, optimize code
Inventory Discrepancies	Stock showing incorrect levels	Race conditions, sync issues	Implement proper locking, audit sync processes
Message Queue Lag	Events not processed timely	Consumer overload, topic misconfiguration	Increase partitions, scale consumers

🔍 Diagnostic Commands

# Check Kubernetes pods status
kubectl get pods -n oms-namespace
kubectl describe pod oms-service-xxx

kubectl top pods -n oms-namespace
kubectl top nodes

# Database connectivity test
kubectl exec -it postgres-pod -- psql -U omsuser -d omsdb -c "SELECT 1;"

# Kafka consumer lag check
kubectl exec -it kafka-pod -- kafka-consumer-groups.sh \
  --bootstrap-server localhost:9092 \
  --describe --group oms-consumer-group

# Redis connectivity test
kubectl exec -it redis-pod -- redis-cli ping

# Port forwarding for local debugging
kubectl port-forward svc/oms-service 8080:8080
kubectl port-forward svc/kafka 9092:9092
