Mainframe TO AWS
January 1, 2025 – May 1, 2025
This project involves the end-to-end migration of legacy mainframe applications and batch jobs to Amazon Web Services (AWS) for AT&T. The goal is to reduce infrastructure cost, improve scalability, and modernize the legacy architecture using a re-platforming approach. The project includes data transformation, environment setup, job validation, and cloud-native implementation aligned with industry best practices. Responsibilities: Performed file trapping and parsing of EBCDIC formatted mainframe datasets. Converted files to ASCII using Data turn (ETL tool) and Data match (validation engine), ensuring 99.9% data consistency. Stored transformed datasets in Amazon S3 with proper lifecycle policies, versioning, and object tagging. Executed and validated batch jobs using AWS EC2 and AWS Batch to mirror original mainframe logic. Monitored job health via AWS CloudWatch and set up proactive alerts for jobs.
