Welcome to this lesson. In this module you take on the role of the DevOps engineer for a cloud-native application. As the solo DevOps engineer, you will design, deploy, operate, and scale the app in the cloud while ensuring reliability, security, and cost efficiency. Core responsibilities
  • Design and implement the CI/CD deployment pipeline.
  • Ensure high availability (HA) and automatic scaling to meet demand.
  • Implement monitoring, centralized logging, and incident response.
  • Manage infrastructure-as-code (IaC), configuration, and secrets.
  • Optimize cost, performance, and security for the cloud environment.

Lesson scope This lesson/article explains the application architecture and the deployment strategy in detail. You will learn how to:
  • Model the architecture for availability and scalability.
  • Implement an end-to-end CI/CD pipeline for automated deployments.
  • Use IaC (Terraform) to provision cloud resources reproducibly.
  • Configure observability (metrics, logs, and alerts) for production readiness.
  • Secure secrets and enforce least-privilege access.
  • Apply cost-optimization techniques and performance tuning.
Recommended prerequisites: basic familiarity with Docker, Linux CLI, Git, and at least one cloud provider (AWS or GCP). Familiarity with CI/CD concepts and infrastructure-as-code (Terraform) will accelerate your progress.
Security note: never commit credentials, API keys, or secrets to source control. Use managed secret stores (e.g., AWS Secrets Manager, HashiCorp Vault) and follow your organization’s IAM best practices.
