Answer options:
Deploy an API Gateway or Application Load Balancer to act as a routing facade.
Perform a one-time cutover of the database using AWS Snowball.
Gradually route specific API paths (e.g., /users) to new AWS Lambda functions or ECS containers.
Use AWS Application Migration Service to lift-and-shift the entire application at once.
Keep the legacy monolith running on-premises or on EC2 to handle un-migrated routes.
Use AWS Database Migration Service (DMS) to keep the legacy and modern databases in sync during the transition.
Use AWS CloudFormation to deploy the monolith.
Use Amazon CloudFront to cache the monolith.
