Today at PowerShell in Action I spoke twice about not going TOO far in your PowerShell when managing Azure resources.
The point of the talks wasn’t really that using PowerShell is bad/wrong, more that it might not be the best tool for the job in certain scenarios. In particular, an ARM template is a powerful modeling tool in support of a “no pets” policy, which is interesting to consider as your cloud environments grow more complex while also wanting to make environments easier to manage. Another benefit stems from keeping the ARM template itself as an “infrastructure as code” artifact that can be used to document – and, more to the point, as executable documentation – for stamping out environments predictably. And still another feature: the ARM runtime handles a lot of the complex parts that could come by trying to script one resource at a time via imperative PowerShell scripts – for example, error recovery and retries.
The deck is on the event shared github repo. There are lots of otherPowerShelly resources on that repo that you may find worth checking out.
(Added 03-June) For those of you who attended my Advanced session, when I attempted to clean up at the end using Remove-AzureRmResourceGroupDeployment, my PowerShell command had an error in it. Here is the correct version. In the first screen shot I show how to ascertain the correct value for the first the parameter using Get-AzureRmResourceGroupDeployment.
Last night I spoke at the North Boston Azure cloud group, where the topic was Azure SQL Database – not just a cloud version of SQL Server. So much of the talk was interactive — a really high-energy discussion — big thanks to Jason for hosting me and to the group for a great conversation.
At the end I attempted to show how I could use the CLI from my macbook to clean up all my demo resources at once by deleting the containing resource group. It failed because I got the syntax wrong. I was typing something like azure resource delete Zoran, but ‘resource’ should have been ‘group’ and I failed to realize that at the time. I ran the correct command when I got home and it worked better. Here is my evidence… 🙂
In case folks were wondering, the PowerShell command equivalent to azure group delete is:
The patterns I dug into are discussed in my book in chapters 2 (horizontal scaling) and 3 (queue pattern):
At today’s October Boston Azure meeting, we celebrated turning 7 years old, and had two talks. I presented one talk related to the Dyn DDoS outage from Friday Oct 21, which illustrated the dark side of IoT since it was used to power a huge DDoS attack on Dyn, taking down Netflix, Github, Spotify, and lots of other sites as collateral damage. In my talk I explained some of the background and how we addressed it with Azure DNS.
Here’s the deck for the “IoT has a dark side” talk:
Jim O’Neil provides some resource relating to his talk. There are listed AS A COMMENT on the meeting page (scroll below the meeting description page to comments – Meetup.com does not allow changing a meeting description after the meeting begins, so amendments tend to be as comments).
The PowerShell script I demo’d is included in the gist referenced below.

I spoke tonight at the New England SQL Server Group to a large audience of feisty SQL experts. Thanks for all the tough questions. And thanks to George for backing me up on questions I couldn’t answer.
The Microsoft Azure cloud platform offers a service called Azure SQL Database. How does this compare to SQL Server, the venerable boxed product so many DBAs have come to know and love? In this talk from long-time Azure MVP Bill Wilder, we will look at similarities and differences. We will also briefly talk about complementary data storage sources that may also interest DBAs. At the end of the talk, you will understand the big picture of database options in the cloud, how Azure SQL Database is positioned and stacks up relative to SQL, and leave with an appreciation of key scenarios where it might make sense to use one over the other.
One thing I didn’t get to work was the PowerShell cleanup at the end. I ran it later and here is the code (the last line is the one I botched during the demo):

At Boston Code Camp 25 (yes, this was the 25th Boston Code Camp!) I presented 17 Specific Azure Security Tips and Tricks. The talk was pretty rapid-fire, with a lot of information. For folks interested in following-up, the deck (included below) includes lots of links to more information.
Also, for those interesting in more information, please check out Boston Azure (bostonazure.org/meetup and @bostonazure), the world’s oldest Azure-focused user group – right here in Boston. We have an all-day bootcamp coming up April 16, among other coming Azure-related action.
