Key point
CJ Logistics migrated its overseas IDC to AWS, achieving 3-year cost parity while targeting a 150-minute cutover.
Details
- Part 2 of the process of migrating CJ Logistics' overseas hub IDCs to AWS, covering the execution and lessons learned from the actual server migration, cutover, and stabilization phases
- To support 24/7 global services, the team targeted a cutover completion within 150 minutes and conducted five rehearsals, but the actual cutover took approximately 200 minutes, resulting in a delay of about 50 minutes from the target
- Operating costs over a 3-year period were nearly identical to those of the previous IDC, but the application of Savings Plans shifted the cost structure from fixed to adjustable
- The cause of DB performance degradation was row-level processing delays in Linked Server; this was resolved by grouping target keys in batches of 1,000 for execution on the remote server, reducing batch time from 12 hours to 6–7 minutes
- The migration framework and standard operating procedures have become reusable assets for future global workload migrations to locations such as the United States and India
- The migration was completed using the Lift & Shift approach, with plans for future modernization based on CI/CD pipeline integration, containers, and managed services
