It provides low latency and high throughput for frequently accessed data, along with built-in encryption at rest for data security. Additionally, Amazon S3 offers cross-region replication, allowing companies to replicate data across multiple geographically distinct locations for durability and fault tolerance. Therefore, Amazon S3 is the appropriate service for this requirement.
