Final-year intern — Cloud & IoT architecture (AKS proof of concept)

Hager Group·Obernai (67), France

Final-year internship with the Architecture & Integration Management team of the IoT Cloud Factory. Brief: build a proof of concept assessing whether Hager's API services could be deployed securely on Azure Kubernetes Service over a private network.

• Owned the end-to-end design of an Azure proof of concept assessing secure IoT service deployment on AKS, from reviewing the existing setup through to validation testing.
• Designed a private Azure architecture split across three virtual networks, using VNet Peering and Private Endpoints to secure traffic between AKS, virtual machines and Azure SQL.
• Containerised and orchestrated .NET IoT APIs with Docker, Docker Compose and Kubernetes; added health checks and resolved Azure SQL connectivity issues.
• Worked around an ARM64 incompatibility in the Docker images by setting up a compatible builder, then an AMD64 node suited to the workloads, plus cluster autoscaling.
• Produced a monthly cost estimate for the target architecture — compute, virtual machines, private networking and messaging — stating the assumptions, limits and items still to refine.
• Built an IoT-based energy prediction prototype within a cross-functional team, presented to a Hager-Microsoft jury at the GenIA hackathon.

R&D intern — Embedded systems, SLAM & operator HMI
