Create an S3 bucket

• Versioning:
  • By default if the same object is uploaded, then s3 will try to overwrite the object.
  • We can enable versioning to avoid this.
  • Once the version is enable it can be suspended but not disabled.
  • lets enable versioning
  • Create an s3 bucket in the configure options tab select enable versioning
  • Enabling and suspending versions can be done even after bucket creation
• Cross Region Replication:
  • Contents of S3 bucket can be replicated from one region to other
  • Enable versioning from cli

  #!/bin/bash
  
  #source bucket details
  s3_bucket_source_name="qts3crossregionsrc"
  source_region="us-west-2"
  
  #target bucket details
  s3_bucket_target_name="qts3crossregiontg"
  target_region="ap-south-1"
  
  # create an s3 bucket
  aws s3 mb --region ${source_region} "s3://${s3_bucket_source_name}"
  
  # Lets enable versioining in source and target buckets
  aws s3api put-bucket-versioning --bucket ${s3_bucket_source_name} \
      --versioining-configuration Status=Enabled
  
  aws s3api put-bucket-versioning --bucket ${s3_bucket_target_name} \
      --versioining-configuration Status=Enabled
  

Athena and S3 Select

• Athena allows you to query the data within s3 as if it is relational database.
• Athena queries are standard sql queries
• S3 Select is similar to Athena, but ita allows you select fragments out of single object in s3 Refer Here

Lifecycle

• AWS S3 buckets gives us lifecycle option to move objects from one storage class to other storage class.
• We can move the objects into glacier as well
• To move the objects only b/w frequent and infrequent tiers we can use aws s3 storage class as Intelligent Tiering.

Next Steps

• Topics
  1. Writing Policies
  2. Writing ACL’s
  3. Querying S3
