Using ARM to Deploy Global Solutions

Imagine deploying your secure load balanced solution to three datacenters, putting in place a worldwide load balancer and doing so in roughly 24 minutes. Did I mention that this deployment is predictable and repeatable?

Good, now that I’ve got your attention, it’s time to dive in!

Building on my previous post about managing compute resources on Azure I decided to modify the Azure Resource Manager(ARM) template to deploy a real-world environment to three datacenters (Yes I know, the diagrams shows two locations, but as I built the demo, I got greedy…). Using Azure Traffic Manager we are able positively affect a users experience by directing them to the closest datacenter.

Its important to note that ARM does not support nested copy operation. This means that we have to use a different strategy to deploy identical environments in multiple Azure regions. After a bit of research it became apparent that I had to use nested deployments. This technique requires us to break our template into multiple files. The parent template in this demo is the azuredeploy-multi-geo.json file. It contains the full list of parameters, a nested deployment that deploys instances of our environment to multiple Azure regions, and a Traffic Manager definition. The azuredeploy.json template file was refactored from the template used in my previous blog post. It contains networking, storage and Virtual Machine definitions. Continue Reading…

Lost in Translation – Azure Networking

In today’s highly connected world, many professionals use Cisco’s terminology to discuss networking. Using the wrong terms can lead to lengthy, confusing arguments. The goal of this post, is to help those of us who don’t speak the language, to communicate effectively with others about Azure Networking.

I’ve been dabbling in the IT Pro space for a few months now, and it’s been a challenge to discuss Azure Networking. Coming from a development background, my reference to networking was Azure. That definitely made it difficult, because I spoke about Virtual Networks, Subnets and Network Security Groups. To help me sort things out, I asked a colleague of mine to identify the equivalencies between Cisco and Azure Networking terminology.

Let’s dive in! Continue Reading…

Why are Virtual Networks Important?

As a developer, I used to forget about Virtual Networks. And to be fair, I shied away from pretty much everything that can be considered as infrastructure.

Microsoft Azure is a game changer! It requires Developers and IT Pros to collaborate on projects. Let’s take a moment to set things right. Developers and IT Pros are not competing against each other in this new world. They collaborate in order to produce value for the business and customers.

As we move to a Cloud First and Mobile First world, security is more important than it ever was. On Microsoft Azure, the first step towards securing your application resources is to create a Virtual Network. Continue Reading…
