Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 156 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 156
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is developing a new serverless API by using Amazon API Gateway and AWS Lambda. The company integrated the Lambda functions with API Gateway to use several shared libraries and custom classes.

A solutions architect needs to simplify the deployment of the solution and optimize for code reuse.

Which solution will meet these requirements?

  • A. Deploy the shared libraries and custom classes into a Docker image. Store the image in an S3 bucket. Create a Lambda layer that uses the Docker image as the source. Deploy the API's Lambda functions as Zip packages. Configure the packages to use the Lambda layer.
  • B. Deploy the shared libraries and custom classes to a Docker image. Upload the image to Amazon Elastic Container Registry (Amazon ECR). Create a Lambda layer that uses the Docker image as the source. Deploy the API's Lambda functions as Zip packages. Configure the packages to use the Lambda layer.
  • C. Deploy the shared libraries and custom classes to a Docker container in Amazon Elastic Container Service (Amazon ECS) by using the AWS Fargate launch type. Deploy the API's Lambda functions as Zip packages. Configure the packages to use the deployed container as a Lambda layer.
  • D. Deploy the shared libraries, custom classes, and code for the API's Lambda functions to a Docker image. Upload the image to Amazon Elastic Container Registry (Amazon ECR). Configure the API's Lambda functions to use the Docker image as the deployment package.

Selected Answer: D
Don't understand why so many people are choosing B. Read up. A container image cannot be used with Lambda layers. That means A B C are out instantly. Its literally one of the first things they mention about Lamba layers. Answer is D and ABC simply impossible to configure. https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html

You can create a Lambda function from an ECR image, but you CANNOT create a Lambda function layer from an ECR image!

https://aws.amazon.com/blogs/compute/working-with-lambda-layers-and-extensions-in-container-images/ Previously, Lambda functions were packaged only as .zip archives. This includes functions created in the AWS Management Console. You can now also package and deploy Lambda functions as container images. You can use familiar container tooling such as the Docker CLI with a Dockerfile to build, test, and tag images locally. Lambda functions built using container images can be up to 10 GB in size. You push images to an Amazon Elastic Container Registry (ECR) repository, a managed AWS container image registry service. You create your Lambda function, specifying the source code as the ECR image URL from the registry.

B suggests deploying the shared libraries and custom classes to a Docker image, uploading it to Amazon Elastic Container Registry (Amazon ECR), creating a Lambda layer that uses the Docker image as the source, and deploying the API's Lambda functions as Zip packages. Configuring the packages to use the Lambda layer simplifies deployment, and the Docker image allows for code reuse. This option takes advantage of the built-in features provided by AWS API Gateway and Lambda, making it the optimal solution.

The requirement is code reuse: https://aws.amazon.com/blogs/compute/working-with-lambda-layers-and-extensions-in-container-images/ Lambda functions packaged as container images do not support adding Lambda layers to the function configuration. However, there are a number of solutions to use the functionality of Lambda layers with container images. You take on the responsible for packaging your preferred runtimes and dependencies as a part of the container image during the build process.

If any of you ever really worked in lambda with docker image, you will instantly choose D without hesitation. zipped package can be deployed straightaway and it doesn't need a container. Don't get those two things(lambda zip deployment vs lambda container deployment) mixed up

Please read the requirement, "simplify the deployment" with D you need only to maintain the docker image, with B you need to maintain the docker image and the process to deploy the lambda as ZIP Packages.

B. * A Lambda layer is a .zip file archive that contains supplementary code or data. Layers usually contain library dependencies, a custom runtime, or configuration files. * Lambda functions packaged as container images do not support adding Lambda layers to the function configuration.However, there are a number of solutions to use the functionality of Lambda layers with container images. You take on the responsible for packaging your preferred runtimes and dependencies as a part of the container image during the build process.
