A company deploys its applications on Amazon Elastic Kubernetes Service (Amazon EKS) behind an Application Load Balancer in an AWS Region.The application needs to store data in a PostgreSQL database engine.The company wants the data in the database to be highly available.The company also needs increased capacity for read workloads.

Which solution will meet these requirements with the MOST operational efficiency?

Create an Amazon DynamoDB database table configured with global tables.

Create an Amazon RDS database with Multi-AZ deployments.

Create an Amazon RDS database with Multi-AZ DB cluster deployment.

Create an Amazon RDS database configured with cross-Region read replicas.

Explanations:

Amazon DynamoDB is a NoSQL database, which does not support PostgreSQL queries or structure. It is not compatible with the requirement for a PostgreSQL database engine.

Amazon RDS Multi-AZ deployment improves availability by replicating to a standby in a different Availability Zone but does not provide increased read capacity, as there are no additional read replicas.

Amazon RDS Multi-AZ DB cluster deployment provides high availability and allows for reader nodes, which increases capacity for read workloads. This solution best meets both high availability and read scalability requirements.

Cross-Region read replicas improve read scalability but are intended for geographically distributed applications and incur additional latency. This solution is more complex operationally than Multi-AZ DB clusters for local scaling.

    I systematize that the answer is:
    Create an Amazon RDS database with Multi-AZ DB cluster deployment.
