# Introduction

> Lesson on deploying and managing Network Virtual Appliances in Azure Virtual Hubs, including attachment, routing, IP configuration, monitoring, and traffic verification

Welcome — this lesson covers Network Virtual Appliances (NVAs) in Azure Virtual Hubs.

Network Virtual Appliances are virtualized network devices—firewalls, routers, load balancers, and other network functions—implemented as virtual machines in your Azure environment. NVAs deliver the same packet-processing, inspection, and routing capabilities as physical appliances but with the flexibility, scalability, and automation benefits of cloud infrastructure.

Typical NVA use cases:

* Centralized security (next-gen firewalls, IDS/IPS)
* Advanced routing and traffic inspection
* WAN optimization and traffic shaping
* SSL/TLS inspection and application-level gateways

Learning outcomes:

* How to monitor and manage an NVA deployed in an Azure Virtual Hub
* How to deploy an NVA into a Virtual Hub: attach it to the hub, configure routing and IPs, and verify traffic flows

| Learning Objective               | What you'll be able to do                                                                        |
