Accelerate Amazon S3 Replication with automated S3 Batch Operations parallelization

This article presents a production-ready solution for automating large-scale S3 data migrations across AWS regions and accounts using S3 Batch Operations, Step Functions, and Lambda.

• Orchestrates concurrent replication jobs using Step Functions to coordinate Lambda, AWS Glue, and S3 Batch Operations
• Automatically configures S3 Inventory reports for buckets exceeding 20 billion objects
• Combines Cross-Region Replication for real-time ongoing replication with S3 Batch Operations for bulk migration
• Provides comprehensive monitoring via CloudWatch and maintains migration state in DynamoDB
• Deploys infrastructure as code using AWS CDK with full GitHub repository for implementation
• Handles parallel processing, data integrity verification, and error handling at scale

The solution reduces operational overhead, improves compliance management, and enables efficient enterprise data migrations without infrastructure overhead.
