Which service is primarily used for storing object data in AWS?

Amazon S3 (Simple Storage Service) is primarily used for storing object data in AWS. It is designed to handle large amounts of unstructured data, such as photos, videos, and backups. S3 operates on the principle of an object storage model, which means that data is stored as objects within buckets. Each object can be up to 5 terabytes in size and is identified by a unique key within its bucket, allowing for easy retrieval.

S3 is highly durable and available, making it well-suited for serving static content or archiving data. It also integrates seamlessly with other AWS services, supporting functionalities like data lifecycle policies, versioning, and replication, which enhance data management and storage efficiency.

The other services mentioned, while they also play critical roles within the AWS ecosystem, are not focused on object storage. Amazon EBS provides block-level storage meant for use with Amazon EC2 instances, catering primarily to applications requiring persistent, high-performance storage. AWS Lambda is a serverless compute service that executes code in response to events but does not provide storage capabilities itself. Amazon RDS is a managed relational database service designed for structured data storage and retrieval in relational databases, where data organization relies on schemas and tables rather than the object storage model used
