Cloud Native Fundamentals

Cloud native architecture is designed to take full advantage of cloud computing models.

Key Principles

  1. Microservices
  2. Containers
  3. DevOps
  4. Continuous Delivery
  5. Service Mesh

Example Microservice

# Docker Compose example
version: '3'
services:
  api:
    build: ./api
    ports:
      - "3000:3000"
    environment:
      - DB_HOST=db
    depends_on:
      - db
  
  db:
    image: postgres:13
    environment:
      - POSTGRES_PASSWORD=secret
    volumes:
      - db-data:/var/lib/postgresql/data

volumes:
  db-data:

Infrastructure as Code

# Terraform example
provider "aws" {
  region = "us-west-2"
}

resource "aws_eks_cluster" "main" {
  name     = "main-cluster"
  role_arn = aws_iam_role.eks_cluster.arn

  vpc_config {
    subnet_ids = var.subnet_ids
  }
}

Best Practices

  1. Design for failure
  2. Implement health checks
  3. Use managed services
  4. Automate everything
  5. Monitor and log extensively
