Amazon S3 is designed to provide scalability, high availability, and low latency at commodity costs. S3 can store an unlimited number of objects and scale automatically as you add more objects to the bucket, making it the perfect choice for a storage solution that needs to handle growing data without manual scaling actions. Amazon EBS provides block storage for use with EC2 instances and does not automatically scale in the same way as S3. Amazon DynamoDB is a NoSQL database service optimized for high-performance, scalable applications but is not primarily a storage service for objects. Amazon EC2 provides computing capacity in the cloud but is not primarily used for object storage.
