A large international university has deployed compute services in AWS, including Amazon EC2, Amazon RDS, and Amazon DynamoDB. The university currently uses many custom scripts for backups and wants to centralize and automate backups using AWS-native options. Which solution meets these requirements?

AWS Backup is the correct solution because it is a fully managed backup service that centralizes and automates backup across various AWS services, including Amazon EC2, Amazon RDS, and Amazon DynamoDB, directly addressing the university's need for AWS-native backup. It allows for policy-based backup plans, retention, and monitoring. Third-party backup software with Storage Gateway is less "AWS-native" and adds complexity compared to AWS Backup. AWS Config tracks resource configurations and changes, but it does not perform backups. AWS Systems Manager State Manager automates server configuration tasks but is not designed for centralized backup management across multiple AWS services.
