AWS Certified Developer - Associate (DVA-C01)

Domain 1: Deployment

Deploy written code in AWS using existing CI/CD pipelines, processes, and patterns.

• Commit code to a repository and invoke build, test and/or deployment actions

• Use labels and branches for version and release management

• Use AWS CodePipeline to orchestrate workflows against different environments

• Apply AWS CodeCommit, AWS CodeBuild, AWS CodePipeline, AWS CodeStar, and AWS CodeDeploy for CI/CD purposes

• Perform a roll back plan based on application deployment policy

• 1.2 Deploy applications using AWS Elastic Beanstalk.

• Utilize existing supported environments to define a new application stack

• Package the application

• Introduce a new application version into the Elastic Beanstalk environment

• Utilize a deployment policy to deploy an application version (i.e., all at once, rolling, rolling with batch, immutable)

• Validate application health using Elastic Beanstalk dashboard

• Use Amazon CloudWatch Logs to instrument application logging

• 1.3 Prepare the application deployment package to be deployed to AWS.

• Manage the dependencies of the code module (like environment variables, config files and static image files) within the package

• Outline the package/container directory structure and organize files appropriately

• Translate application resource requirements to AWS infrastructure parameters (e.g., memory, cores)

Deploy serverless applications

• Given a use case, implement and launch an AWS Serverless Application Model (AWS SAM) template

• Manage environments in individual AWS services (e.g., Differentiate between Development, Test, and Production in Amazon API Gateway)

Domain 2: Security

Make authenticated calls to AWS services

• Communicate required policy based on least privileges required by application.

• Assume an IAM role to access a service

• Use the software development kit (SDK) credential provider on-premises or in the cloud to access AWS services (local credentials vs. instance roles)

Implement encryption using AWS services.

• Encrypt data at rest (client side; server side; envelope encryption) using AWS services

• Encrypt data in transit

• Implement application authentication and authorization.

• Add user sign-up and sign-in functionality for applications with Amazon Cognito identity or user pools

• Use Amazon Cognito-provided credentials to write code that access AWS services.

• Use Amazon Cognito sync to synchronize user profiles and data

• Use developer-authenticated identities to interact between end user devices, backend authentication, and Amazon Cognito

Domain 3: Development with AWS Services

Write code for serverless applications.

• Compare and contrast server-based vs. serverless model (e.g., micro services, stateless nature of serverless applications, scaling serverless applications, and decoupling layers of serverless applications)

• Configure AWS Lambda functions by defining environment variables and parameters (e.g., memory, time out, runtime, handler)

• Create an API endpoint using Amazon API Gateway

• Create and test appropriate API actions like GET, POST using the API endpoint

• Apply Amazon DynamoDB concepts (e.g., tables, items, and attributes)

• Compute read/write capacity units for Amazon DynamoDB based on application requirements

• Associate an AWS Lambda function with an AWS event source (e.g., Amazon API Gateway, Amazon CloudWatch event, Amazon S3 events, Amazon Kinesis)

• Invoke an AWS Lambda function synchronously and asynchronously
