2022/11/29 - AWS Lambda - 8 updated api methods
Changes Adds support for Lambda SnapStart, which helps improve the startup performance of functions. Customers can now manage SnapStart based functions via CreateFunction and UpdateFunctionConfiguration APIs

Creates a Lambda function. To create a function, you need a deployment package and an execution role . The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.
If the deployment package is a container image , then you set the package type to Image . For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.
If the deployment package is a .zip file archive , then you set the package type to Zip . For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64 ). If you do not specify the architecture, then the default value is x86-64 .
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 Lambda 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A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration.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 Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).
You can use code signing if your deployment package is a .zip file archive. 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 of signing profiles, which define the trusted publishers for this function.
If another Amazon Web Services account or an Amazon Web Service invokes your function, use AddPermission to grant permission by creating a resource-based Identity and Access Management (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 Amazon Web Services, create an event source mapping ( CreateEventSourceMapping ), or configure a function trigger in the other service. For more information, see Invoking Lambda 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.
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 .

Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing for Lambda .
If the function's package type is Image , then you must specify the code package in ImageUri as the URI of a container image in the Amazon ECR registry.
If the function's package type is Zip , then you must specify the deployment package as a .zip file archive . Enter the Amazon S3 bucket and key of the code .zip file location. You can also provide the function code inline using the ZipFile field.
The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64 ).
The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.
Note
For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

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 Lambda 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 Amazon Web Services account or Amazon Web Service, use AddPermission .
