 In industries like manufacturing, segmented networking architectures (such as the [Purdue Network Architecture](https://en.wikipedia.org/wiki/Purdue_Enterprise_Reference_Architecture)) are common. These architectures create layers that minimize or block lower-level segments from connecting to the internet. Azure IoT Operations supports secure management of devices in these layered networks using open, industry-recognized software, and Kubernetes-based configuration.

+A [layered networking guidance sample](https://github.com/Azure-Samples/explore-iot-operations/tree/main/samples/layered-networking) is available in the Azure IoT Operations samples repository. The guidance describes the environment Microsoft uses to validate Azure IoT Operations deployments in a layered network. The sample and guidance show how to:
 
-- Use Kubernetes-based configuration and networking primitives for layered environments
-- Connect devices in isolated networks at scale to [Azure Arc](/azure/azure-arc/) for application lifecycle management and remote configuration
-- Enforce security and governance across network levels with URL/IP allowlists and connection auditing
-- Ensure compatibility with all Azure IoT Operations services
