IOT Platform

IoT Platform for Device Management and Real-Time Monitoring

The IoT platform was designed and implemented to provide efficient device communication, monitoring, and real-time alerting using the Open Source CloudEdge Package (Hono, Ditto). This platform enables seamless management of IoT devices, digital twin representation, and high-frequency telemetry data analysis. By leveraging Docker, Minikube, and modern database solutions, the platform ensures scalability and production-ready performance.

The IoT platform is designed as a multi-tenant system with a single solution approach, featuring three administrative roles: superadmin, tenant admin, and user admin. Superadmins can manage tenants (add, edit, delete, and view), monitor system health (including resource usage), create solution schemas to define the framework, develop device schemas to facilitate device addition, and handle asset management by assigning devices to the appropriate tenants.
