AWS Cloud Skill

This skill provides AWS architecture patterns and best practices.

Core Services

Service	Use Case
EC2	Virtual servers
Lambda	Serverless functions
S3	Object storage
RDS	Managed databases
ECS/EKS	Container orchestration
CloudFront	CDN
Route 53	DNS

Well-Architected Framework

Operational Excellence - Automation, monitoring
Security - IAM, encryption, compliance
Reliability - Multi-AZ, backups, DR
Performance - Right-sizing, caching
Cost Optimization - Reserved instances, spot

Terraform Patterns

hcl

# VPC with public/private subnets
module "vpc" {
  source = "terraform-aws-modules/vpc/aws"

  name = "my-vpc"
  cidr = "10.0.0.0/16"

  azs             = ["us-east-1a", "us-east-1b"]
  private_subnets = ["10.0.1.0/24", "10.0.2.0/24"]
  public_subnets  = ["10.0.101.0/24", "10.0.102.0/24"]

  enable_nat_gateway = true
}

Security Best Practices

Use IAM roles, not access keys
Enable MFA for root and IAM users
Encrypt data at rest (KMS)
Use VPC for network isolation
Enable CloudTrail for audit
Use Security Groups as firewalls

Cost Optimization

Use Reserved Instances for steady workloads
Use Spot Instances for flexible workloads
Right-size instances based on metrics
Use S3 lifecycle policies
Enable Cost Explorer alerts
