Cloud-native isn't just about running in the cloud — it's a set of principles and practices that make applications more resilient, scalable, and maintainable.
Core Cloud-Native Principles
- Microservices architecture
- Containerization (Docker)
- Orchestration (Kubernetes)
- CI/CD automation
- Observability (metrics, logs, traces)
- Immutable infrastructure
Security Best Practices
- Shift-left security — scan images in CI
- RBAC & least privilege everywhere
- Secrets management (Vault, AWS Secrets Manager)
- Network policies & service mesh (Istio/Linkerd)
Observability Stack Recommendation (2024–2025)
- Metrics: Prometheus + Grafana
- Logs: Loki / OpenSearch
- Tracing: Jaeger / Tempo + OpenTelemetry
Start small: containerize one service, deploy to Minikube or Kind, then move to real clusters.
