• Refer Here for docs on Storage classes
• Standard:
  • This is default storage classes
  • High storage cost and less access costs
  • Used of frequently accessed data
• One Zone
  • Same as standard except Redundancy

• Standard-IA (Infrequent Access)
  • We pay less for storage and more for access
• One Zone – IA (Infrequent Access)
  • Same as standard-IA except Redundancy
  • The Redundancy is in one zone
• Glacier: Built for archival storage i.e. cheapest storage costs
  • Instant Retrieval
  • Deep Archive
  • Flexible Retrieval
• Intelligent Tiering: AWS ML models will choose the storage class according to your access patterns

Changing Storage Class

• While uploading object, the storage class can be chosen
  
• Post creation used Actions
  
• If there is a pattern such first 60 days, data is frequently used, then for next 90 days infrequently post that for 1 year almost no access after that i don’t need this file anymore, AWS has lifecycle where we can transition the data from one storage class to other
