Experience

Intuition

The Intuition portal app provides internet services such as wireless, fiber internet, dark fiber, VoIP, and unified communication services in the USA and Canada and I was the DevOps architect initiating the migration journey of the entire infrastructure to AWS and managing it through code instead of manual processes using AWS CDK. I implemented a highly available architecture with EKS; it spans three availability zones with a virtual private cloud (VPC) configured with public and private subnets and a cluster autoscaler to automatically adjust the number of nodes in the cluster when pods fail or are rescheduled onto other nodes. I used blue and green deployment strategies to increase the application availability and reduce deployment risks by simplifying the rollback process if a deployment fails.

Technologies used in this solution include the Amazon Elastic Kubernetes Service (EKS), Amazon Relational Database Service (RDS), Amazon Aurora, Amazon Application Load Balancers (ALB), Istio, Amazon Elastic Container Registry (ECR), Prometheus, Grafana, Loki for logging, Amazon CloudWatch, and Amazon GuardDuty. I also used AWS CodePipeline, Argo CD, and Argo Rollouts for the CI/CD pipeline.
