Answer: Adopt Amazon Aurora MySQL, deploying read replicas across regions with regional endpoints for access.
The correct answer is B. Amazon Aurora MySQL with read replicas across multiple regions is well-suited for this scenario because it provides high availability, low latency, and global consistency for the reservation database. Aurora supports multi-region read replicas, which means the primary database can stay consistent across regions while providing low-latency reads and writes. Unlike DynamoDB, which is a NoSQL database, Aurora MySQL is an SQL-based database, making it easier to migrate the current setup to Aurora.
