Understand migration tools—Application Migration Service (MGN), DMS/SCT (DB migration), DataSync (online bulk transfer), the Snow Family (offline bulk), and Transfer Family. Choose by data type and connectivity.
- 4.3Modernizing on the Cloud
Understand post-migration modernization—containers (ECS/EKS/Fargate), serverless, decomposing into microservices, and incremental migration via the strangler fig pattern. Improve agility, scale, and cost-efficiency.
