# Overview of the Project
> Hands-on DevOps project teaching design, deployment, and operation of a cloud-native application with CI/CD, IaC, monitoring, security, scaling, and cost optimization
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.
Table: Responsibilities mapped to typical activities and tools
| Responsibility | Typical Activities | Example tools / commands |
| --------------------------- | ------------------------------------------------------: | --------------------------------------------------------------- |
| Deployment pipeline | Build, test, and promote artifacts through environments | CI: GitHub Actions / GitLab CI; `docker build`, `kubectl apply` |
| High availability & scaling | Multi-AZ deployments, autoscaling, load balancing | AWS ELB/ALB, Kubernetes HPA, Auto Scaling Groups |
| Monitoring & logging | Metrics, alerting, centralized logs, incident playbooks | Prometheus + Grafana, ELK/EFK, PagerDuty |
| IaC & config management | Provisioning infra, managing env-specific config | Terraform, AWS CloudFormation, `terraform apply` |
| Secrets & security | Secret rotation, least privilege, encryption | HashiCorp Vault, AWS Secrets Manager, IAM policies |
| Cost & performance | Rightsizing, reserved instances, caching | AWS Cost Explorer, CloudWatch, Redis |
What is the application?
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.
