## AI overview

AWS Lambda now supports self-managed Amazon S3 buckets for function deployment packages. Lambda reads code directly from the customer-controlled bucket, removing deployment-package copies from the Lambda code storage quota and giving teams control over encryption, access policies, compliance, lifecycle management, audit trails, and cross-Region replication.

## Source excerpt
