Day 21: S3 Lifecycle Policies

πŸ“¦ Day 21: S3 Lifecycle Policies – Automate Data Management in AWS

Category: AWS Storage
Goal: Learn how to automatically move or delete data in S3 based on rules.


🧠 What You’ll Learn Today:

  • What S3 Lifecycle Policies are
  • How to set up lifecycle rules
  • Use cases to save storage costs
  • Key terms: Transition, Expiration, Storage Classes

πŸ—‚οΈ 1. What Are Lifecycle Policies in S3?

Lifecycle policies help you automate the movement or deletion of objects stored in S3.

➑️ You can set rules like:

  • Move data to cheaper storage after 30 days
  • Delete files after 90 days

This helps in saving money and managing storage smartly.


πŸ”‘ 2. Key Terms to Know

TermMeaning
TransitionMove objects to a different storage class (like S3 Standard β†’ S3 Glacier)
ExpirationAutomatically delete objects after a set number of days
Storage ClassType of S3 storage (Standard, IA, Glacier, Deep Archive, etc.)

πŸ”„ 3. Example Lifecycle Rule

πŸ“ Rule:

  • Files older than 30 days β†’ move to S3 Infrequent Access (IA)
  • Files older than 90 days β†’ move to S3 Glacier
  • Files older than 365 days β†’ delete

πŸš€ This saves costs by using cheaper storage for older data.


πŸ› οΈ 4. How to Set It Up

  1. Go to your S3 bucket
  2. Click on Management tab
  3. Choose “Create lifecycle rule”
  4. Define:
    • Rule name
    • Scope (all objects or specific prefix/tags)
    • Transitions
    • Expiration
  5. Review and create

πŸ”’ Tip: Lifecycle rules are non-destructive during testing β€” you can use them in a limited scope first.


βœ… 5. Real-World Use Cases

  • Auto-archive logs after 30 days
  • Delete old backups after 1 year
  • Move rarely accessed reports to Glacier
  • Clean up temporary files

🧠 End of the Day Notes:

πŸ’‘ Lifecycle policies = “set it and forget it” for managing your S3 data.
πŸ’Έ They help you reduce costs without deleting important files too early.
πŸ“Š Always analyze your usage and access patterns before applying transitions.
