 # Azure IoT Operations networking
 
-Networking is a foundational aspect of deploying and managing distributed systems, especially in hybrid and multi-cloud environments. In Azure IoT Operations, secure networking enables reliable connectivity between on-premises resources, edge devices, and Azure services. Proper network configuration is essential for communication, security, and scalability of IoT Operations and Kubernetes clusters. This article describes key networking options for IoT Operations.

 ## Azure Arc gateway
 
-The Azure Arc gateway acts as a network proxy, allowing you to onboard and manage servers that do not have direct internet access. By routing traffic through the gateway, you can simplify firewall rules and reduce the need for complex network changes. This approach is especially useful for securely connecting isolated or segmented environments to Azure Arc and Azure IoT Operations.

 ## Layered networking sample
 
-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 practical networking sample is available in the [Azure IoT Operations samples repository](https://github.com/PatAltimore/explore-iot-operations/tree/patricka-layered-network/samples/layered-networking). This sample demonstrates 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 allow lists and connection auditing

 - Ensure compatibility with all Azure IoT Operations services
 - Enable bifurcation for targeted endpoints
