AWS Classroom Series – 29/May/2021

Managing storage lifecycle

• To manage objects so that they are stored cost effectively, we use lifecycle
• An S3 lifecycle configuration is a set of rule that define actions that applies to group of objects

  • Transition action:

    • defines when the objects transition to from one storage class to other
    • There are costs associated with the lifecycle transition requests
    • Supported transitions

  • Expiration action: Define when the object expires

• Lets create a life cycle configuration

Replicating Objects

• Replication enables automatic, asynchronous copying of objects across S3 buckets.

• Buckets that are configured for object replicated

  • can be owned by same AWS account or different
  • Can be replicated into different AWS regions.
  • Can be replicated to one S3 bucket or multiple S3

• To enable object replication, we need to provide the following details

  • The destination bucket(s)
  • AWS IAM role that Amazon s3 can assume to replicate objects on your behalf

• Setting up replication

Using S3 Versioning

• Versioning in S3 means keeping multiple variants of the objects in the same bucket

Exercise

• Create an s3 bucket
  • Add a folder called as images
  • upload 10 images
• Find the storage class of any image
• Add one more folder called as docs
  • upload a file called as Readme.txt
  • Enable Versioning for the bucket
• Upload two more versions and verify the presence of versions
• Create a life cycle rule to
  • move all the objects older than 60 days to Standard-IA

AWS CLI

AWS S3 CLI

1. S3URI: The format for s3 bucket and object naming

s3://<bucket-name>
Eg:
s3://qts3bucket

2. Commands
   • ls => listing
   • cp => copying
   • mb => create bucket
   • mv => moving the objects
   • rb => removing bucket
   • rm => removing the objects
3. Listing buckets and its contents
4. Listing s3 buckets folder contents
