Problem

The organization needed to establish a secure, scalable foundation for Industrial Internet of Things (IIoT) deployments. Remote field devices required reliable data collection capabilities, and the enterprise lacked standardized approaches for IIoT architecture, security, and data processing. There was a need for a proof of concept that could serve as a template for future IIoT initiatives.

Solution

  • Designed and implemented a cellular-based IIoT architecture for remote field device connectivity.
  • Utilized MQTT protocol for efficient, lightweight messaging between edge devices and cloud.
  • Implemented Azure IoT Hub for device management, authentication, and data ingestion.
  • Built serverless data processing using Azure Functions and messaging queues.
  • Ensured enterprise-grade security with TLS certificates and robust authentication.
  • Established technical standards and best practices for future IIoT deployments.
