What is Cloud-Native?

TL;DR

Cloud-native is an approach to building and running applications that fully exploits the advantages of the cloud computing model — elasticity, scalability, and managed services.

Core pillars: - Containerization: Packaging applications in Docker/OCI containers - Orchestration: kubernetes" class="text-cyan-400 hover:text-cyan-300 underline underline-offset-2 decoration-cyan-500/30 transition-colors">Kubernetes for container management - Microservices: Decomposed, independently deployable services - Service mesh: Infrastructure layer for service-to-service communication - Immutable infrastructure: Replace rather than update infrastructure - Declarative APIs: Define desired state, let the system reconcile

Cloud-native does NOT mean: "We use AWS/Azure/GCP." Many cloud-hosted applications are not cloud-native. Running a monolith on EC2 is cloud-hosted, not cloud-native.

Why It Matters

Cloud-native architecture enables rapid scaling and deployment but creates significant operational complexity. The engineering cost of managing Kubernetes, service meshes, and container orchestration is a form of infrastructure technical debt.

Frequently Asked Questions

Is cloud-native always better?

No. Cloud-native architecture makes sense for large-scale, distributed systems with multiple teams. For small teams and simple applications, a well-built monolith deployed on managed services (Vercel, Railway, Heroku) is often more cost-effective.
