Domain về triển khai ứng dụng, CI/CD, và Infrastructure as Code. Domain này chiếm 20% nội dung thi, tương đương khoảng 13 câu hỏi.

Tổng quan

Phần quan trọng của application build là thiết kế scalable, efficient, và cost-effective deployment solution.

Deployment solutions bao gồm:

• Cách update application version
• Cách manage supporting infrastructure throughout complete application lifecycle

Deployment Lifecycle Factors

• Resource provisioning - Tạo và quản lý resources
• Configuration management - Quản lý cấu hình
• Application deployment - Triển khai ứng dụng
• Software updates - Cập nhật phần mềm
• Monitoring - Giám sát
• Access control - Kiểm soát truy cập

AWS Deployment Services

AWS provides services cho management capabilities của application lifecycle:

• Có thể dùng standalone hoặc combined
• Balance giữa manual management và AWS managed resources
• Giúp build và deliver applications rapidly và reliably

4 Task Statements

Task 3.1: Prepare application artifacts to be deployed to AWS

• Manage dependencies của code module trong package
• Organize files và directory structure cho deployment
• Use code repositories trong deployment environments
• Apply application requirements cho resources
• Access application configuration data

Task 3.2: Test applications in development environments

• Test deployed code bằng AWS services và tools
• Perform mock integration cho APIs
• Resolve integration dependencies
• Test applications bằng development endpoints
• Deploy application stack updates to existing environments

Task 3.3: Automate deployment testing

• Create application test events
• Deploy API resources to various environments
• Create application environments với approved versions cho integration testing
• Implement và deploy Infrastructure as Code (IaC) templates
• Manage environments trong individual AWS services

Task 3.4: Deploy code by using AWS CI/CD services

• Update existing IaC templates
• Manage application environments bằng AWS services
• Deploy application version bằng deployment strategies
• Commit code to repository to invoke build, test, deployment actions
• Use orchestrated workflows to deploy code to different environments
• Perform application rollbacks bằng existing deployment strategies
• Use labels và branches cho version và release management
• Use existing runtime configurations to create dynamic deployments
