Answer: Amazon S3 Standard
The correct answer is Amazon S3 Standard. Amazon S3 Standard is designed for frequently accessed data and provides low latency and high throughput performance, which meets the requirement for data to be accessible in milliseconds. Moreover, it is a cost-effective solution for storing data that needs to be retained for a short period, such as 30 days. Other options such as Amazon OpenSearch Service, Amazon S3 Glacier, and Amazon RDS for PostgreSQL either do not offer the required performance characteristics or are not as cost-effective for this specific use case.
