S3 Contd

Bucket Deletion

• S3 bucket deletion requires the bucket to be empty before deleting
  

Amazon S3 Access Control

• One way of giving access is through IAM Policies which is common to all services in AWS
• In S3 we can create policies at bucket level which is called as bucket policy
• Lets create an S3 bucket
• Create two folders and upload some objects into it with default values (don’t change permissions)
• In S3 to provide access we have two mechanisms
  • ACL:
    • Older Authorization mecahnism
    • ACLS the have simple mechanism (They have ALLOW but no deny)
      
      
      
      
    • This is no longer the recommonded approach as we can give read, list write permissions only
  • Bucket policy
    • New Method
    • Policies can implement very complex rules and permissions
