2 - Overview of the services

2.1 Code* services

Service	Description	Equivalent
CodeCommit	Private Git repositories	GitHub, GitLab
CodeBuild	Build and tests	Jenkins, CircleCI
CodeDeploy	Automated deployment	Octopus Deploy
CodePipeline	CI/CD orchestration	Jenkins Pipeline
CodeArtifact	Artifact repository	Nexus, JFrog

2.2 Reference architecture

3 - Benefits of AWS DevOps

3.1 Native integration

• All services work together natively
• Unified authentication with IAM
• No complex plugin configuration
• Native support for EC2, ECS, EKS, Lambda

3.2 Scalability

• Fully managed services
• No infrastructure to manage
• Scales automatically with load
• Pay-per-use

3.3 Security

• Encryption at rest and in transit
• IAM for fine-grained access control
• Integration with Secrets Manager
• Audit trail with CloudTrail

cd my-first-repo

# Ajouter du code
echo '{"name": "my-app"}' > package.json
git add .
git commit -m "Initial commit"
git push origin main
