Overview

The Infrastructure domain provides foundational platform services that enable all business applications across payments, tax-free, and hospitality verticals. This includes AWS and Azure cloud infrastructure, Kubernetes cluster management, GitOps-based deployments via ArgoCD, and the Internal Developer Portal (Backstage).

Key Responsibilities

AWS and Azure cloud infrastructure provisioning (VPCs, EKS, networking)
Kubernetes cluster lifecycle and baseline configurations
ArgoCD-based GitOps deployment management
Internal Developer Portal (IDP) via Backstage
Platform Management Services (PMS) for standardized infrastructure patterns
