Prepare artifacts, test applications, automate testing, and deploy using CI/CD services (~24% of exam).
Covers preparing application artifacts including dependency management, directory structure organization, code repositories, resource requirements, and environment-specific configurations with AWS AppConfig. Also covers testing applications in development environments including deployed code testing, integration tests with mock APIs, development endpoints and API Gateway stages, stack updates to staging environments, and event-driven application testing. Additionally covers automating deployment testing including test events, API resource deployment, version management with Lambda aliases and container tags, IaC templates (SAM, CloudFormation), environment management, and Amazon Q Developer for automated tests. Finally covers CI/CD deployment including Lambda packaging, API Gateway stages and custom domains, IaC template updates, deployment strategies (blue/green, canary, rolling), version control, orchestrated workflows, and application rollbacks.

Deployment in AWS refers to the process of releasing and managing application code and infrastructure in the AWS cloud environment. For the AWS Certified Developer - Associate exam, understanding deployment strategies and services is crucial.
**AWS Elastic Beanstalk** is a Platform-as-a-Service (PaaS) that simplifies deployment by handling infrastructure provisioning, load balancing, auto-scaling, and application health monitoring. Developers simply upload their code, and Beanstalk manages the rest.
**AWS CodeDeploy** is a fully managed deployment service that automates application deployments to Amazon EC2 instances, on-premises servers, Lambda functions, and ECS services. It supports multiple deployment strategies:
- **In-Place Deployment**: Updates existing instances by stopping the application, installing new code, and restarting.
- **Blue/Green Deployment**: Creates a new environment alongside the existing one, then shifts traffic to the new version, enabling easy rollback.
- **Canary Deployment**: Gradually shifts traffic to the new version in increments.
- **Linear Deployment**: Shifts traffic in equal increments over time.
**AWS CodePipeline** orchestrates the entire CI/CD workflow, integrating source control, build, test, and deployment stages into an automated pipeline.
**Amazon ECS and EKS** provide container deployment options, supporting rolling updates and blue/green deployments for containerized applications.
**AWS Lambda** enables serverless deployment where you upload function code and AWS handles all infrastructure management. Lambda supports versioning and aliases for traffic shifting between function versions.
**AWS CloudFormation** uses Infrastructure as Code (IaC) to deploy and manage resources through templates, ensuring consistent and repeatable deployments.
Key deployment concepts include understanding deployment configurations, rollback mechanisms, lifecycle hooks in CodeDeploy, environment variables, and health checks. The exam tests knowledge of selecting appropriate deployment strategies based on requirements like minimizing downtime, risk mitigation, and cost optimization.Deployment in AWS refers to the process of releasing and managing application code and infrastructure in the AWS cloud environment.
