Set Up Cross-Region S3 Bucket Replication

Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. In this lab, we explore how to use Amazon S3 to automatically replicate any object stored in our S3 bucket to a different region on the other side of the country. This process ensures our files remain accessible in any extreme scenario where data loss could possibly occur. By the end of this lab, you will understand how to create S3 buckets and enable automatic replication to back up files in a different physical location.

Challenge

Create an S3 Bucket and Enable Replication
1. Copy the name of the lab-provided appconfigprod1 bucket and use it to create a new S3 bucket in the US West (Oregon) us-west-2 region, replacing appconfigprod1 with appconfigprod2 to ensure it is globally unique.
  
  Note: After creating the new bucket, you may receive a warning about system tags; you can safely ignore it.
2. Enable automatic file replication from the appconfigprod1 S3 bucket to the appconfigprod2 S3 bucket.
Challenge

Test Replication and Observe Results
1. Upload a file to the appconfigprod1 S3 bucket.
2. Ensure the file was automatically replicated to the appconfigprod2 S3 bucket.
