+A book store app powered by AWS EKS. Application is designed in microservices fashion running on EKS and integrating with other AWS Services. This project was based on learning from [ACloudGuru](https://acloudguru.com/course/a-practical-guide-to-amazon-eks)
+
+## Key Features
+1. AWS Infrastructure (IaC) via Terraform.
+2. Microservice Style - APIs and Front End in different language.
+3. Docker Compose for local testing.
+4. Heml for Kubernetes Deployment.
+5. IRSA for Kubernetes using IAM.
+6. External DNS to manage Route53.
+7. ALB Controller for Load Balancing.
+8. App Mesh (Envoy) for Kubernetes.
+9. X-Ray for Tracing.
+10. CI/CD Pipeline for automated build and deployment of Kubernetes.

+ kubectl delete -f prod.yaml
+ kubectl delete -f appmesh-system.yaml
+```
+2. Remove K8S. 
+```
+kubectl delete -f infrastructure\k8s-tooling\alb-controller\alb-ingress-controller.yaml
+kubectl delete -f infrastructure\k8s-tooling\external-dns\external-dns.yaml
