Harry Johnson developed a Traefik Ingress Controller in chaining mode with an Nginx fallback for the dspace-group/simphera-reference-architecture-aws repository, focusing on enhancing traffic management and architectural resilience within AWS-based cloud infrastructure. By wiring Traefik to manage ingress traffic and configuring Nginx in ClusterIP mode as a fallback, he improved service availability and minimized disruption during controller issues. Harry implemented this solution using Kubernetes, Terraform, HCL, and YAML, ensuring robust deployment and reproducibility. He also documented the new ingress architecture and deployment steps, supporting faster onboarding and maintainability. The work demonstrated depth in cloud-native traffic management and infrastructure automation.
