Case Study: Transport System Modernization

We helped a key government body transition critical transport applications to a cloud-native, microservices-based architecture using Amazon EKS.

Overview

This project focused on re-architecting legacy transport applications that were running on outdated infrastructure. By leveraging Amazon EKS, we enabled the deployment of scalable microservices, improved automation, and centralized operations — aligning with public sector digital transformation initiatives.

Challenges

  • Monolithic design hindered scalability and maintainability.
  • Manual release processes led to frequent delays and downtime.
  • Compliance requirements necessitated secure, auditable deployments.
  • Lack of container strategy across departments created environment drift.

What We Delivered

  • Refactored core transport applications into containerized services using Docker and deployed them on Amazon EKS.
  • Developed a standardized Kubernetes-based microservices architecture, enabling horizontal scalability.
  • Created reusable Terraform modules to automate EKS cluster provisioning and IAM policies.
  • Integrated Jenkins for end-to-end CI/CD, including security scanning, build/test, and deploy workflows.
  • Implemented role-based access control (RBAC) for DevOps teams and audit logging for government compliance.
  • Enabled auto-scaling and observability with Prometheus and AWS CloudWatch integrations.
