Detailed AWS Architecture Review Audit Checklist

1. Reliability

Design for Failure:

• Auto Scaling:

  aws autoscaling describe-auto-scaling-groups
  aws autoscaling create-auto-scaling-group --auto-scaling-group-name my-asg --launch-configuration-name my-lc --min-size 1 --max-size 10 --desired-capacity 2 --vpc-zone-identifier subnet-12345678,subnet-87654321

Backup and Restore:

• AWS Backup:

  aws backup list-backup-plans
  aws backup create-backup-plan --backup-plan '{"BackupPlanName": "MyBackupPlan","Rules": [{"RuleName": "DailyBackups","TargetBackupVaultName": "Default","ScheduleExpression": "cron(0 12 * * ? *)","StartWindowMinutes": 60,"CompletionWindowMinutes": 180,"Lifecycle": {"DeleteAfterDays": 30}}]}'

Monitoring:

• CloudWatch Alarms:

  aws cloudwatch describe-alarms
  aws cloudwatch put-metric-alarm --alarm-name "HighCPUUsage" --metric-name CPUUtilization --namespace AWS/EC2 --statistic Average --period 300 --threshold 80 --comparison-operator GreaterThanOrEqualToThreshold --evaluation-periods 2 --alarm-actions arn:aws:sns:us-east-1:123456789012:my-sns-topic

Disaster Recovery:

• Route 53 Failover:

  aws route53 list-health-checks
  aws route53 create-health-check --caller-reference 2021-01-01T12:00:00Z --health-check-config '{"IPAddress":"192.0.2.44","Port":80,"Type":"HTTP","ResourcePath":"/","RequestInterval":30,"FailureThreshold":3}'

---

2. Security

Identity and Access Management:

• IAM Policies:

  aws iam list-policies
  aws iam create-policy --policy-name MySecurityPolicy --policy-document file://policy.json

Data Encryption:

• KMS Keys and S3 Bucket Encryption:

  aws kms list-keys
  aws kms create-key --description "My KMS key"
  aws s3api put-bucket-encryption --bucket my-bucket --server-side-encryption-configuration '{"Rules": [{"ApplyServerSideEncryptionByDefault": {"SSEAlgorithm": "aws:kms"}}]}'

Network Security:

• VPC Security Groups:

  aws ec2 describe-security-groups
  aws ec2 create-security-group --group-name my-sg --description "My security group"
  aws ec2 authorize-security-group-ingress --group-name my-sg --protocol tcp --port 22 --cidr 0.0.0.0/0

Logging and Monitoring:

• CloudTrail:

  aws cloudtrail describe-trails
  aws cloudtrail create-trail --name my-trail --s3-bucket-name my-bucket
  aws cloudtrail start-logging --name my-trail

---

3. Cost Optimization

Resource Management:

• AWS Cost Explorer:

  aws ce get-cost-and-usage --time-period Start=2023-07-01,End=2023-07-31 --granularity MONTHLY --metrics "UnblendedCost" "UsageQuantity"

Reserved Instances:

• Purchase Reserved Instances:

  aws ec2 describe-reserved-instances
  aws ec2 purchase-scheduled-instances --instance-count 1 --purchase-request '{"InstanceCount": 1, "PurchaseToken": "token"}'

Right-Sizing:

• Modify Instance Types:

  aws ec2 describe-instances
  aws ec2 modify-instance-attribute --instance-id i-1234567890abcdef0 --instance-type t2.medium

Cost Allocation Tags:

• Tagging Resources:

  aws resourcegroupstaggingapi get-resources
  aws ec2 create-tags --resources i-1234567890abcdef0 --tags Key=Environment,Value=Production

---

4. Operational Excellence

Infrastructure as Code:

• AWS CloudFormation:

  aws cloudformation describe-stacks
  aws cloudformation create-stack --stack-name my-stack --template-body file://template.json

Automation:

• AWS Systems Manager:

  aws ssm list-commands
  aws ssm send-command --document-name "AWS-RunShellScript" --targets '[{"Key":"instanceIds","Values":["i-1234567890abcdef0"]}]' --parameters '{"commands":["sudo yum update -y"]}'

Incident Response:

• Config Rules:

  aws configservice describe-config-rules
  aws configservice put-config-rule --config-rule '{"ConfigRuleName": "s3-bucket-policy-check","Source": {"Owner": "AWS","SourceIdentifier": "S3_BUCKET_POLICY"}}'

Runbooks:

• Automation Documents:

  aws ssm list-documents --document-filter-list key=Owner,value=Self
  aws ssm create-document --content file://my-automation-document.json --name MyAutomationDocument --document-type Automation

---

5. Performance Efficiency

Scalable Architectures:

• Elastic Load Balancing:

  aws elbv2 describe-load-balancers
  aws elbv2 create-load-balancer --name my-load-balancer --subnets subnet-12345678 subnet-87654321 --security-groups sg-12345678

Caching:

• Amazon ElastiCache:

  aws elasticache describe-cache-clusters
  aws elasticache create-cache-cluster --cache-cluster-id my-cluster --cache-node-type cache.m4.large --engine redis --num-cache-nodes 3

Performance Monitoring:
