1. Developer Workstations

   • Developers commit code to a GitHub repository.

2. Continuous Integration

   • Jenkins pulls the latest code from GitHub.
   • Builds and tests the application.
   • Creates Docker images and pushes them to Amazon ECR.

3. Infrastructure as Code

   • Terraform provisions AWS infrastructure:
     • VPC
     • IAM Roles and Policies
     • EKS Cluster
     • RDS

4. Continuous Deployment

   • Jenkins deploys Docker images to EKS.
   • Istio manages traffic between microservices.

5. Service Mesh

   • Istio provides traffic management, security, and observability.
   • Ingress Gateway manages external access.

6. Monitoring and Logging

   • Prometheus collects metrics.
   • Grafana visualizes metrics.
   • Fluentd centralizes logging.
   • Alertmanager integrates with Prometheus for alerting.

7. Continuous Feedback

   • Alertmanager sends notifications.
   • Jenkins provides feedback to developers.
