Infrastructure: Python Microservices on K8s
This architecture is designed for horizontal scale and high availability. It moves away from single-process VMs to a managed container orchestration layer.
Core Components:
- Kubernetes Cluster: Managed K8s (EKS, GKE, AKS) provides the orchestration layer.
- Ingress Controller: Handles external traffic routing and SSL (e.g., NGINX or Traefik).
- Service Mesh: (Optional but recommended) Handles mTLS and service-to-service observability (e.g., Linkerd or Istio).
- Python Pods: Horizontal Pod Autoscalers (HPA) manage the number of replicas based on CPU/Memory load.
- Managed Database: Highly available RDS or Cloud SQL instances.
- Cloud Storage: S3/GCS for media and assets.
