Overview

Amazon S3 provides secure, durable, and highly scalable object storage. Manage buckets with encryption, versioning, access controls, lifecycle policies, and cross-region replication for reliable data storage and retrieval.

When to Use

• Static website hosting
• Data backup and archival
• Media library and CDN origin
• Data lake and analytics
• Log storage and analysis
• Application asset storage
• Disaster recovery
• Data sharing and collaboration

Quick Start

Minimal working example:

# Create bucketaws s3api create-bucket \  --bucket my-app-bucket-$(date +%s) \  --region us-east-1
# Enable versioningaws s3api put-bucket-versioning \  --bucket my-app-bucket \  --versioning-configuration Status=Enabled
# Block public accessaws s3api put-public-access-block \  --bucket my-app-bucket \  --public-access-block-configuration \    BlockPublicAcls=true,IgnorePublicAcls=true,\    BlockPublicPolicy=true,RestrictPublicBuckets=true
# Enable encryptionaws s3api put-bucket-encryption \  --bucket my-app-bucket \  --server-side-encryption-configuration '{    "Rules": [{      "ApplyServerSideEncryptionByDefault": {        "SSEAlgorithm": "AES256"      }// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Enable versioning for important data
• Use server-side encryption
• Block public access by default
• Implement lifecycle policies
• Enable logging and monitoring
• Use bucket policies for access control
• Enable MFA delete for critical buckets
• Use IAM roles instead of access keys
• Implement cross-region replication

❌ DON'T

• Make buckets publicly accessible
• Store sensitive credentials
• Ignore CloudTrail logging
• Use overly permissive policies
• Forget to set lifecycle rules
• Ignore encryption requirements
