Description

This addition introduces comprehensive support for Azure IoT Operations, Microsoft's unified industrial IoT platform, to the AzureRM Terraform provider. The implementation includes a complete suite of resources that enable users to deploy and manage edge-to-cloud IoT solutions through Infrastructure as Code. The core foundation begins with the azurerm_iotoperations_instance resource, which serves as the container for all IoT Operations components and requires deployment to Arc-enabled Kubernetes environments via custom locations. Built upon this foundation is the azurerm_iotoperations_broker resource, providing a scalable MQTT message broker with configurable cardinality for both backend (partitions, redundancy, workers) and frontend (replicas, workers) components. Network connectivity is handled through azurerm_iotoperations_broker_listener resources, which support multiple protocols (MQTT, WebSockets, HTTP) with enterprise-grade security features including TLS encryption, cert-manager integration for automated certificate lifecycle management, and configurable authentication and authorization policies. The platform's data processing capabilities are enabled through azurerm_iotoperations_dataflow resources that define transformation and routing workflows, supported by azurerm_iotoperations_dataflow_profile resources for performance tuning and azurerm_iotoperations_dataflow_endpoint resources for connecting to external systems like Azure Data Explorer, Storage accounts, and Event Hubs. Security and access control are managed through dedicated azurerm_iotoperations_broker_authentication and azurerm_iotoperations_broker_authorization resources, providing fine-grained control over device and application access to the MQTT broker. This comprehensive resource set enables organizations to implement complete industrial IoT scenarios with edge computing capabilities, real-time data processing, secure device communication, and seamless integration with Azure cloud services, all managed declaratively through Terraform's infrastructure-as-code approach.
