Azure Stack SDN

Monitoring and rapid incident response are essential in modern hybrid data centers. Azure Local SDN environments deliver rich network telemetry, but acting on this data in real time is a challenge—unless you connect it to workflow automation tools. In this guide, you’ll learn how to integrate Azure Local SDN logs and telemetry with Microsoft Power … Read more

Executive Summary Modern hybrid and edge datacenters demand agile visibility into software-defined networks. For Azure Local SDN (formerly Azure Stack HCI SDN), network object sprawl and multi-tenant overlays can complicate operations. Manually documenting your SLB, subnet, and gateway relationships in Visio is time-consuming and error-prone. These diagrams remain essential for compliance, troubleshooting, audits, and rapid … Read more

TL;DR Summary Azure Local SDN (formerly Azure Stack HCI SDN) provides powerful native microsegmentation and routing capabilities. But for organizations with existing investments in Palo Alto Networks or Fortinet firewalls—or specific compliance mandates—integrating these third-party Network Virtual Appliances (NVAs) remains a strategic choice. In this article, we explore the how, why, and when of embedding … Read more

TL;DR: Quick Summary Azure Policy enables organizations to enforce and continuously audit compliance across their Azure environments. This article focuses on how Azure Policy helps validate and enforce best practices for Network Security Groups (NSGs) and Azure Firewall configurations. You’ll get definitions, use cases, benefits, sample policies, PowerShell commands, and Bicep templates for secure, scalable … Read more

TL;DR: Quick Summary Azure Software Defined Networking (SDN) delivers flexible, scalable, and secure virtual networking across Azure cloud and Azure Local (formerly Azure Stack HCI). This blog post explores Azure SDN’s core components—including Azure Firewall, Network Security Groups (NSGs), Application Security Groups (ASGs), service tags, and rule formatting—along with design and implementation best practices for … Read more

TL;DR: Quick Summary Microsoft Azure’s network security model—featuring Azure Firewall Manager, Network Security Groups (NSGs), and Application Security Groups (ASGs)—provides scalable, application-aware, and cloud-native protection across both cloud and hybrid infrastructures. When extended via Azure Arc, these tools deliver superior policy management, automation, and integration capabilities compared to VMware NSX Distributed Firewall (DFW). This article … Read more
