2020/11/23 - AWS Lambda - 9 new 11 updated api methods
Changes This release includes support for new feature: Code Signing for AWS Lambda. This adds new resources and APIs to configure Lambda functions to accept and verify signed code artifacts at deployment.
Creates a code signing configuration. A code signing configuration defines a list of allowed signing profiles and defines the code-signing validation policy (action to be taken if deployment validation checks fail).

Creates a Lambda function. To create a function, you need a deployment package and an execution role . The deployment package contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.
When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State , StateReason , and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Function States .
A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.
The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration . Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).
To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode , Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this function.
If another account or an AWS service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.
To invoke your function directly, use Invoke . To invoke your function in response to events in other AWS services, create an event source mapping ( CreateEventSourceMapping ), or configure a function trigger in the other service. For more information, see Invoking Functions .

Creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.
AWS Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.
Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias .

Modify the version-specific settings of a Lambda function.
When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Function States .
These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.
To configure function concurrency, use PutFunctionConcurrency . To grant invoke permissions to an account or AWS service, use AddPermission .
