EKS Container Platform

Kubernetes-Based VPN Deployment with Zero-Trust Security

🚀 The Challenge: A client needed secure internal access to private cloud services without exposing Kubernetes clusters externally. Traditional VPN solutions were costly and difficult to manage.

🔒 The Solution: Deployed a scalable VPN solution using Pritunl and MongoDB inside Amazon EKS with Ingress-based TLS termination, secret management via Vault, and fully automated Helm chart delivery.

🚨 The Challenge & Solution

The Problem

The client needed secure internal access to private cloud services without exposing Kubernetes clusters externally. Traditional VPN solutions were either too costly, difficult to manage, or didn't align with cloud-native security best practices.

Critical Issues:
  • Security Risks: Exposing Kubernetes clusters to the internet
  • High Costs: Enterprise VPN solutions with complex licensing
  • Management Overhead: Multiple point solutions lacking automation
  • Access Control: Difficulty implementing fine-grained permissions
  • Compliance: Meeting security standards for internal access

The Solution

Deployed a scalable VPN solution using Pritunl and MongoDB inside Amazon EKS with Ingress-based TLS termination, secret management via Vault, and fully automated Helm chart delivery.

Key Benefits:
  • Zero external exposure with maximum security
  • 75% reduction in VPN-related expenses
  • 5-minute automated deployments
  • Enterprise-grade security and compliance
  • GitOps deployment model
