Overview
How each tool is described
AWS IoT SiteWise
What is AWS IoT SiteWise?
AWS IoT SiteWise is a managed industrial data service for collecting, organizing, storing, processing, and analyzing equipment data at scale. It combines industrial data ingestion, asset modeling, time-series storage, native anomaly detection, edge connectivity, and a generative AI assistant for operational analysis.
- Industrial data role: SiteWise Edge collects plant data from sources such as OPC UA and can use MQTT-enabled V3 gateways to route industrial data through MQTT topics. Asset models, component models, interfaces, and hierarchies then organize measurements and relationships around real equipment, production lines, and facilities. Partner integrations can extend connectivity to additional industrial protocols.
- AI capabilities: native anomaly detection trains managed machine-learning models on selected equipment properties to identify abnormal behavior and contributing sensors without requiring teams to build the models themselves. AWS IoT SiteWise Assistant combines operational data, asset models, manuals, and other knowledge-base content to summarize events, answer diagnostic questions, explore root causes, and provide guided recommendations through natural-language interactions.
- Implementation checks: buyers should assess gateway architecture, industrial protocols, asset-model design, data frequency and retention, bandwidth, AWS Region availability, and integration requirements. They should also distinguish edge collection from edge processing: the Data Collection Pack remains available, but the Data Processing Pack has been unavailable to new customers since November 7, 2025 and remains only for existing customers in maintenance mode. Native anomaly detection also has more limited Region availability than the core SiteWise service.
- Commercial considerations: SiteWise uses usage-based pricing across messaging, computation, storage, queries, export, and related capabilities. SiteWise Assistant has a monthly enablement fee plus API usage, while native anomaly detection is billed according to model-training time and inference frequency. AWS’s current pricing example lists a $120 monthly Assistant enablement fee, before usage charges.
AWS IoT SiteWise is particularly relevant to asset-intensive organizations that need a standardized industrial data layer with equipment modeling, scalable time-series analytics, predictive anomaly detection, and AI-assisted investigation within the AWS ecosystem.
Azure IoT
What is Azure IoT?
Azure IoT is Microsoft’s portfolio of cloud and edge services for connecting, managing, modeling, and analyzing IoT devices and industrial assets. Rather than being a single product, it combines services such as Azure IoT Hub, Azure IoT Operations, Azure Device Registry, Azure Digital Twins, and downstream Azure or Microsoft Fabric analytics.
- Connectivity role: Azure IoT Hub provides device-to-cloud telemetry and, on its Standard and Free tiers, cloud-to-device messaging, device twins, and device-management capabilities. Azure IoT Operations runs on Azure Arc-enabled Kubernetes at industrial sites, using an edge-native MQTT broker, OPC UA connectivity, and data flows to process, contextualize, and route operational data locally or to cloud services such as Microsoft Fabric.
- Asset management: Azure Device Registry represents devices and industrial assets as Azure Resource Manager resources so they can be governed with Azure tools, policies, tags, and RBAC. It is generally available with Azure IoT Operations; integration with Azure IoT Hub remains in preview. Azure Digital Twins separately models live relationships between physical environments, business systems, and connected-device data as a graph.
- Implementation checks: buyers should assess cloud-versus-edge connectivity patterns, industrial protocols, Kubernetes and Azure Arc requirements, device provisioning, update processes, telemetry volumes, security policies, data residency, offline requirements, and integration with services such as Event Hubs, Data Lake Storage, Azure Data Explorer, or Microsoft Fabric.
- Commercial considerations: pricing varies by service. IoT Hub is priced by selected tier, hub units, and message capacity, while Azure IoT Operations uses pay-as-you-go billing based on participating Kubernetes nodes. Azure Device Registry is billed according to registered assets and devices, with device billing having taken effect on May 1, 2026. Other services such as Azure Digital Twins have their own usage-based meters.
Azure IoT is particularly relevant to organizations that want a Microsoft-based architecture spanning cloud-connected devices, industrial edge workloads, governed asset management, digital models, and downstream analytics or AI rather than a single packaged IoT application.
