I want to know any housekeeping approach for S3?

Kidd Ip · Accepted Answer

Yes, simply below:

1.	Enable Versioning:
Keep track of changes to objects by enabling versioning. This helps recover previous versions if needed.
2.	Lifecycle Policies:
Use lifecycle policies to automatically transition objects to cheaper storage classes (e.g., Glacier) or delete them after a certain period.

While S3 is not designed to host database services directly, it does require some housekeeping practices to maintain efficiency and cost-effectiveness. Here are some approaches for S3 housekeeping:

1. Lifecycle Policies: Implement S3 Lifecycle policies to automatically transition objects between storage classes or delete them after a certain period. This helps optimize storage costs and manage data retention.

2. Versioning: If you have versioning enabled, regularly review and clean up old versions of objects to prevent unnecessary storage costs.

3. Access Control: Regularly audit and update bucket policies, IAM policies, and Access Control Lists (ACLs) to ensure proper security measures are in place.

4. Encryption: Ensure that your data is encrypted, either using server-side encryption (SSE) or client-side encryption, depending on your security requirements.

5. Monitoring and Logging: Enable S3 access logging and CloudTrail to monitor access patterns and detect any unusual activity.

6. Tagging: Use S3 object tagging to organize and categorize your data, making it easier to manage and apply policies.

7. Cross-Region Replication: If needed for disaster recovery or data locality, set up cross-region replication for critical data.

8. Inventory Reports: Regularly generate and review S3 inventory reports to understand your storage usage and object metadata.

9. Cost Optimization: Analyze your storage patterns and consider using S3 Intelligent-Tiering for data with unknown or changing access patterns to automatically optimize costs.

10. Bucket Cleanup: Periodically review and delete unnecessary buckets or objects to reduce clutter and potential security risks.

By implementing these housekeeping practices, you can maintain an efficient, secure, and cost-effective S3 environment, even though S3 itself is not suitable for hosting database services directly.

To add to the points mentioned by others, you can add couple of other security settings.
* Enable "Block Public Access" for the bucket and even for the account if possible
* Update bucket policy and allow traffic over TLS only. (https://repost.aws/knowledge-center/s3-enforce-modern-tls)
* Use VPC endpoints to make sure the traffic stays within the AWS environment
