// Creates a Lambda function. To create a function, you need a deployment package (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html)
// and an execution role (https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html#lambda-intro-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 (https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html)
// , 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 (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-zip)
// , 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 (https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html)
// . A function has an unpublished version, and can have published versions and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 The unpublished version changes when you update your function's code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 (https://docs.aws.amazon.com/lambda/latest/dg/lambda-invocation.html) .
