6 Pillars Of AWS Well-Architected Framework

You Should Know:

1. Operational Excellence:

Automate routine tasks using AWS Lambda:

aws lambda create-function --function-name my-function --runtime python3.8 --handler lambda_function.lambda_handler --role arn:aws:iam::123456789012:role/lambda-execution-role --zip-file fileb://function.zip

Use AWS CloudFormation for infrastructure as code:

aws cloudformation create-stack --stack-name my-stack --template-body file://my-template.json --parameters ParameterKey=KeyPairName,ParameterValue=MyKey

2. Security:

Enable AWS CloudTrail for monitoring:

aws cloudtrail create-trail --name my-trail --s3-bucket-name my-bucket --is-multi-region-trail

Encrypt S3 buckets:

aws s3api put-bucket-encryption --bucket my-bucket --server-side-encryption-configuration '{"Rules": [{"ApplyServerSideEncryptionByDefault": {"SSEAlgorithm": "AES256"}}]}'

3. Reliability:

Set up Auto Scaling:

aws autoscaling create-auto-scaling-group --auto-scaling-group-name my-asg --launch-configuration-name my-launch-config --min-size 1 --max-size 3 --vpc-zone-identifier subnet-123456

Use AWS Backup for automated backups:

aws backup create-backup-vault --backup-vault-name my-vault

4. Performance Efficiency:

Use AWS Elastic Load Balancing:

aws elbv2 create-load-balancer --name my-load-balancer --subnets subnet-123456 subnet-654321 --security-groups sg-123456

Optimize EC2 instances:

aws ec2 modify-instance-attribute --instance-id i-1234567890abcdef0 --instance-type t2.micro

5. Cost Optimization:

Use AWS Cost Explorer:

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

Set up AWS Budgets:

aws budgets create-budget --account-id 123456789012 --budget '{"BudgetName": "my-budget", "BudgetLimit": {"Amount": "100", "Unit": "USD"}, "TimePeriod": {"Start": "2023-01-01", "End": "2023-12-31"}, "TimeUnit": "MONTHLY"}'

6. Sustainability:

Use AWS Compute Optimizer:

aws compute-optimizer get-recommendation-summaries --region us-east-1

Monitor energy usage with AWS CloudWatch:

aws cloudwatch put-metric-alarm --alarm-name cpu-mon --metric-name CPUUtilization --namespace AWS/EC2 --statistic Average --period 300 --threshold 80 --comparison-operator GreaterThanOrEqualToThreshold --dimensions Name=InstanceId,Value=i-1234567890abcdef0 --evaluation-periods 2 --alarm-actions arn:aws:sns:us-east-1:123456789012:my-sns-topic --unit Percent
