I just noticed that the Microsoft Virtual Academy has a new course: Azure Networking Fundamentals for IT Pros. It's narrated by Aaron Farnell, and consists of 4 modules comprising of 4 modules taking around 120 minutes (including assessment time). The MVA rates the technical level as 300 – which is fairly deep but not overly deep!
This MVP course consists of 4 modules:
- Intro to Azure Network Basics and VPN requirements
- Plan and Design your Cloud network infrastructure
- Configuring Azure and On-Premises
- Testing Connectivity and Monitoring
This is a good start to understanding Azure Networking! And like all MVA courses, you can download the MP4s of each module and take then on the road with you.
