A county assessor still runs Oracle on premises and wants lower database license cost in AWS while keeping a managed relational engine. Which migration approach best targets that cost goal?
Select an answer to reveal the explanation.
Short Explanation
Oracle licenses feel like a tax meter that never sleeps. Move the workload to Aurora PostgreSQL with SCT and DMS and you stop paying that meter. Bigger EC2 Oracle boxes just relocate the bill.
Full Explanation
Heterogeneous migration with AWS Schema Conversion Tool and Database Migration Service lets the county move from Oracle to Aurora PostgreSQL-Compatible Edition, reducing commercial database license cost while retaining a managed relational service. Rehosting Oracle on EC2 preserves license exposure. CloudFront caching and SQS do not replace an OLTP assessor database or remove Oracle licensing.
