At the fundamental awareness level, individuals should have a basic understanding of what Amazon S3 is and its primary features. They should be able to recognize the use cases for Amazon S3 and understand how it fits into the broader AWS ecosystem.

Novices should be able to perform basic operations in Amazon S3, such as creating buckets, uploading, downloading, and deleting files. They should also be able to set up basic bucket policies. At this stage, they are still learning and may need guidance to complete tasks.

At the intermediate level, individuals should be comfortable configuring bucket permissions, using versioning, implementing lifecycle policies, enabling logging, and integrating S3 with AWS CloudFront. They can handle common tasks and troubleshoot simple issues independently.

Advanced users should be able to implement more complex features like Cross-Region Replication, event notifications, Transfer Acceleration, and securing buckets using IAM roles. They should also be able to optimize S3 performance. They can handle complex tasks and troubleshoot most issues without assistance.

Experts should be capable of designing and implementing complex S3 architectures, troubleshooting any S3 issues, integrating S3 with other AWS services, automating operations using SDKs and APIs, and implementing advanced security measures. They have a deep understanding of S3 and can handle any task or issue that arises.
