DEThis is how a REAL DevOps CI/CD architecture works in production 🚀
Simple. Automated. Reliable.
A developer pushes code to GitHub / GitLab.
That push automatically triggers Jenkins.
Jenkins acts as the CI/CD engine:
• Checks out code
• Builds and tests the application
• Builds Docker images
• Pushes images to AWS
• Deploys to Kubernetes
Infrastructure is not created manually.
Terraform (IaC) provisions everything: VPC, subnets, EKS cluster, node groups, IAM roles, load balancer, and monitoring.
The application runs on Amazon EKS (Kubernetes): • Frontend Pod
• Backend Pod
• Kubernetes Services
An Ingress with Application Load Balancer (ALB) exposes the app securely and enables zero-downtime deployments.
The data layer is kept outside Kubernetes (best practice):
• Amazon RDS for relational data
• DynamoDB for key-value / session data
Monitoring and reliability are built in:
• Prometheus collects metrics
• Grafana visualizes dashboards
• CloudWatch tracks logs and alarms
When something breaks: Alerts flow through SNS → Email / Slack
So teams know before users complain.
This is real DevOps: ✔ CI/CD
✔ Infrastructure as Code
✔ Kubernetes
✔ Monitoring & alerts
✔ Production-ready design
If you understand this flow, you’re already thinking like a DevOps engineer in real companies.
