The record

Purpose: AWS Signer is a fully managed code-signing service that helps verify code integrity and publisher trust.
Signing workflows: It supports signing AWS Lambda deployment packages, code for supported IoT devices, and container images using Notation.
Lambda integration: AWS Lambda verifies signatures and package integrity when signed code is deployed.
Container integration: Signer works with Notation to sign container images in registries such as Amazon ECR, with signatures stored alongside images for verification.
Other integrations: AWS Signer documentation lists integrations with AWS Certificate Manager and CloudTrail, as well as Amazon EKS image verification.
Access controls: Administrators use AWS Identity and Access Management policies to control which users, groups, and roles can access Signer resources and actions.
Signing profiles: Signing profiles can be created and managed using the Signer console, AWS CLI, or API.
Certificate management: Signer manages signing certificates and keys for Lambda and container image workflows; IoT workflows can use a code-signing certificate imported into AWS Certificate Manager.
Download platforms: The Notation CLI and Signer plugin installers are listed for Linux, macOS, and Microsoft Windows.
API quotas: API actions have per-second quotas by AWS account and Region, and AWS Signer does not offer a minimum API request rate.
Who it is for: AWS describes Lambda signing as a way for organizations to define trusted publishers and let authorized developers generate certified code packages.
AWS launch: AWS says it launched Amazon Web Services in spring 2006.
Price from: Free
