Cloud Native Architecture Best Practices

Introduction

Cloud native is no longer a new concept, but real-world implementation remains challenging. This article shares our best practices and lessons learned in cloud-native architecture.

Microservice Design Principles

• Single responsibility：Each service does one thing well
• Independent deployment：Services are decoupled and can be released independently
• Data isolation：Each service manages its own data
• API Gateway：Unified entry point simplifies client calls

Kubernetes in Practice

• Resource management：Set proper requests and limits
• Health checks：Configure liveness and readiness probes
• Auto-scaling：Leverage HPA and VPA for dynamic adjustment
• Config management：Use ConfigMap and Secret

Observability

Three pillars: Logging, Metrics, and Tracing. We recommend the Prometheus + Grafana + Jaeger tech stack.

CI/CD Best Practices

GitOps workflow using ArgoCD for declarative continuous deployment. Infrastructure as Code — all changes are traceable.

Summary

There are no shortcuts on the cloud-native journey. Teams need to continuously learn and optimize through practice.
