Introduction to Azure Virtual Networking (ARM)

Cloud based virtual networks are software based, and they provide a standard way to organize and isolate Virtual Machines running in the cloud. A virtual network controls addressing, DNS settings, security policies, and routing tables.

Virtual Networks which are commonly referred to as “v-nets”, are isolated from one another. Due to the isolation you can create networks for development, testing, and production that use the same address blocks.

To allow even further isolation, v-nets support subnets, which allow you to segment the network. Subnets will allow you to break out VMs by their purpose, which is common with tiered architectures. For example, if you have an application broken out into front-end and back-end tiers, then you might want to create two subnets, one for the front-end VMs, and another for the back-end tier.

If you're familiar with traditionally networking componets then you're going to feel right at home working with v-nets. So, if you're looking to learn more, then start in on the first lesson!

Final thoughts Wrapping up the course



Welcome back! When it comes to Azure, networking is one of the core components, which makes understanding virtual networks worthwhile.

So that begs the question, what’s next?

In order to master something, it’s important to get your hands dirty.
If you didn’t follow along with the demos, I recommend trying it out for yourself. You don’t need to build out the same thing that I did, however build something. Start with something simple, and begin increasing the complexity.

I hope you found this course useful. Like I mentioned at the start of the course, I’d love to hear your feedback. It doesn’t matter if it’s positive or negative feedback, because hearing from you helps to shape future content.

You can reach me a few different ways. You can reach me on the community forums. You can reach me via email via info@cloudacademy.com. Also, I’m @sowhelmed on Twitter.

I hope to hear from you. Let me know what you like about the course, what you don’t like and what sort of content you’d like to see in the future.

I’m Ben Lambert, from myself and Cloud Academy, thanks for watching!
