Infrastructure as Code

OpenTofu

hcl

# AWS Example (OpenTofu - open-source Terraform fork)
provider "aws" {
  region = "us-east-1"
}

resource "aws_ecs_cluster" "main" {
  name = "app-cluster"
}

resource "aws_ecs_service" "app" {
  name            = "app-service"
  cluster         = aws_ecs_cluster.main.id
  task_definition = aws_ecs_task_definition.app.arn
  desired_count   = 2
  launch_type     = "FARGATE"

  network_configuration {
    subnets         = var.private_subnets
    security_groups = [aws_security_group.app.id]
  }

  load_balancer {
    target_group_arn = aws_lb_target_group.app.arn
    container_name   = "app"
    container_port   = 8000
  }
}

Pulumi (Python)

python

import pulumi
import pulumi_aws as aws

cluster = aws.ecs.Cluster("app-cluster")

service = aws.ecs.Service("app-service",
    cluster=cluster.arn,
    desired_count=2,
    launch_type="FARGATE",
    task_definition=task_definition.arn,
    network_configuration=aws.ecs.ServiceNetworkConfigurationArgs(
        subnets=private_subnet_ids,
        security_groups=[security_group.id],
    ),
)

Deployment Patterns

AWS ECS Fargate

yaml

# task-definition.json
{
  "family": "app",
  "networkMode": "awsvpc",
  "requiresCompatibilities": ["FARGATE"],
  "cpu": "256",
  "memory": "512",
  "containerDefinitions": [{
    "name": "app",
    "image": "123456789.dkr.ecr.us-east-1.amazonaws.com/app:latest",
    "portMappings": [{"containerPort": 8000}],
    "environment": [
      {"name": "DATABASE_URL", "valueFrom": "arn:aws:secretsmanager:..."}
    ],
    "logConfiguration": {
      "logDriver": "awslogs",
      "options": {
        "awslogs-group": "/ecs/app",
        "awslogs-region": "us-east-1",
        "awslogs-stream-prefix": "app"
      }
    }
  }]
}

GCP Cloud Run

bash

# Deploy to Cloud Run
gcloud run deploy app \
  --image gcr.io/project/app:latest \
  --platform managed \
  --region us-central1 \
  --allow-unauthenticated \
  --set-env-vars "DATABASE_URL=..." \
  --min-instances 1 \
  --max-instances 10

DigitalOcean App Platform

yaml

# app.yaml
name: my-app
services:
  - name: api
    github:
      repo: user/repo
      branch: main
    run_command: uvicorn main:app --host 0.0.0.0 --port 8080
    instance_size_slug: basic-xxs
    instance_count: 2
    envs:
      - key: DATABASE_URL
        scope: RUN_TIME
        value: ${db.DATABASE_URL}

databases:
  - name: db
    engine: PG
    version: "16"

Networking

VPC Design

code

Production VPC (10.0.0.0/16)
├── Public Subnets (10.0.1.0/24, 10.0.2.0/24)
│   └── Load Balancers, NAT Gateways
├── Private Subnets (10.0.10.0/24, 10.0.11.0/24)
│   └── Application containers
└── Database Subnets (10.0.20.0/24, 10.0.21.0/24)
    └── RDS, ElastiCache

Security Groups

hcl

resource "aws_security_group" "app" {
  name   = "app-sg"
  vpc_id = aws_vpc.main.id

  ingress {
    from_port       = 8000
    to_port         = 8000
    protocol        = "tcp"
    security_groups = [aws_security_group.alb.id]
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

Secrets Management

AWS Secrets Manager

bash

# Create secret
aws secretsmanager create-secret \
  --name app/production/database \
  --secret-string '{"url":"postgresql://..."}'

# Reference in ECS
"secrets": [{
  "name": "DATABASE_URL",
  "valueFrom": "arn:aws:secretsmanager:us-east-1:123456:secret:app/production/database:url::"
}]

GCP Secret Manager

bash

# Create secret
echo -n "postgresql://..." | gcloud secrets create db-url --data-file=-

# Access in Cloud Run
gcloud run services update app \
  --set-secrets="DATABASE_URL=db-url:latest"

Cost Optimization

•Use spot/preemptible instances for non-critical workloads
•Right-size instances based on metrics
•Reserved instances for steady-state workloads
•Auto-scaling based on demand
•Clean up unused resources (EBS, snapshots, IPs)

Best Practices

•Multi-AZ deployments for high availability
•Use managed services where possible
•Encrypt data at rest and in transit
•Tag all resources for cost allocation
•Infrastructure as Code for reproducibility
•Regular security audits and compliance checks
