Networking

Introduction

This is a set of labs that has been used in the US to onboard new customers and enable their technical people on networking in Azure. The labs will take you through some of the basics, getting you hands on with both the portal and the Azure CLI, and each lab is simplified in order to demonstrate a specific aspect of Azure networking.

Each lab has a lab diagram to describe the target configuration in each lab, and they naturally build on each other until you are covering more advanced areas such as user defined routes, vNet peering, Virtual WAN and Azure Firewall.

Please use the comments section below to give us feedback on the labs, or to suggest other Azure networking areas you would like to see covered.

Labs

Here are the individual lab sections:

Lab	Name	Description
1	Virtual Networks	Create a vNet with two subnets and a couple of VMs
2	Network Security Groups	Create layer 4 ACLs and apply at the subnet level
3	Azure CLI	Create a vNet, a VM and attach an NSG using the Azure CLI
4	vNet Peering	Peer two vNets together and allow communication between them
5	vNet Peering - Transitive Behaviour	Understand how transitive peering works
6	NVA CSR1000v	Learn how to deploy network virtual appliances from the Marketplace
7	Routing Tables	Customise the routing tables to force traffic through the NVA
8	Site-to-site VPN	See how S2S VPNs are configured
9	Virtual WAN	Use Microsoft’s backbone for your WAN and understand the hub and branch topology
10	Standard Load Balancer	Create a load balancer to distribute traffic to backend VMs
11	Network Watcher NSG Flow Logs	Look at the flow content of packets to the VMs
12	Firewall	Explore hub and spoke topologies and centralise control using Azure Firewall
13	Firewall - Inbound NAT	Configure inbound NAT to SSH to a VM within a spoke
14	Firewall - Spoke to Spoke	Use the Firewall to forward traffic between spokes

It is recommended to run through the labs in order as they build on each other.

Futures

The current format of these lab guides is pdf. If a page loads up but looks blank then you may need to just scroll down a little!

If the labs prove as popular as we think they will be then we’ll aim to transpose these into standard markdown over time, and perhaps bring them directly into the Azure Citadel repository.
