Azure World Newsletter – Issue 3.11

June 15, 2022

Welcome to the eleventh edition of the Azure World Newsletter in 2022. 

Some of you may know that I moved from Canada to Portugal this past winter. So I was able to avoid most of the snow and sub-zero temperatures. (Hey Canada! I love you, but I’m not going to miss the snow!) 

But as we head into the summer season here in Portugal, I am not sure what to expect. Just as someone born in a tropical climate struggles with their first winter in Canada, the reverse should also be true. It might take me a few years to adapt to the hotter sun here. Thank goodness for air conditioning until then.

Thanks so much for being a subscriber! The unsubscribe link is at the bottom if you want to stop receiving these emails.


Microsoft Learn continues to roll out new ways for people to learn Azure. 

I talked about Exam Readiness videos and Cloud Games in the last newsletter. 

Shortly after that newsletter went out, they announced Azure Skills Navigator. This is a set of guides designed to help you develop the skills required for certain careers.

For instance, if you want to become an Azure Solution Architect, there is a Skills Navigator to guide you. They also have guides for the following professions:

  • System Administrators
  • Developers
  • AI Developers
  • Data Engineers
  • Data Scientists

Each guide is a PDF download. It contains links to the usual MS Learn Paths. As well as the certifications to earn along the way.

(Of course, I have you covered if you need video courses for any of the certifications. Check out my Udemy profile for those courses: )

The Skills Navigator for each career also contains videos, case studies, diagrams, tools, and other resources. So it incorporates a lot of types of resources in the learning journey.

Get started with this here:


We sometimes talk about how companies choose between the various cloud platforms based on several factors. Price is certainly one, data center locations are another, and the compatibility with existing software and tools might be a third. 

But what is rarely discussed is “real measured performance.” How does an EC2 instance on AWS perform compared to an Azure Virtual Machine, all things being equal? How does an AWS Lambda function perform compared to an Azure Function app? Also, you can compare network speeds and storage I/O performance.

Cockroach Labs has been doing annual performance surveys for the last 3 years. This year, they declare a “statistical dead heat” between AWS, Azure, and Google Cloud performance.

They measure the performance of the cloud platforms across 56 instance types and 107 configurations, over 3000 runs. They measure OLTP, CPU, network, and storage I/O performance.

In past years, performance was always close. But they were able to pick a winner in each of the categories. For instance, in 2020, Cockroach Labs said all three clouds were within 5% of each other. That’s a really close race. And that race is now a tie.

Even if you’re not concerned with the performance of other clouds, the research here shows some interesting results for the ideal mix between vCPU and RAM. They measured the observed performance of each Azure instance type and mapped the increase (or decrease) in performance you’ll likely see as you go from one type to another. 

For example, you’re more likely to see a more consistent performance if your instance has more RAM. Said another way, saving a bit of money by choosing an instance with a lower RAM to vCPU ratio delivers more inconsistent results.

That report is here if you’re interested:


The following announcements were made in the last two weeks:

  • Azure Bastion IP-based connection, in GA
  • Manage Azure Web Application Firewall policies in Azure Firewall Manager, in preview
  • Conversational language understanding (CLU, a successor to LUIS), in GA
  • ExpressRoute IPv6 Support for Global Reach, in preview
  • Trusted launch support for virtual machines using Ephemeral OS disks, in GA
  • MongoDB increases document limit to 16MB, in preview
  • Linux emulator with Azure Cosmos DB API for MongoDB, in preview
  • Azure Cosmos DB serverless container storage limit increased to 1TB, in preview
  • Azure Monitor Agent is available on the latest Linux distros
  • Azure Arc-enabled System Center Virtual Machine Manager, in preview
  • API Management reusable policy fragments
  • Static Web Apps CLI is now available
  • Linux portal editing for Azure Functions, in preview
  • Azure Container Apps support custom domains and TLS certificates
  • Multiple Azure Load Testing features in public preview
  • Azure SDK for Go
  • Private link support in Azure Application Gateway, in preview

Check out the Azure Updates page if any of these affect you.


All of the AZ-900 practice tests (in the video course and in the separate practice test course) have now been updated to the latest exam objectives.

I have now started re-recording the AZ-305 course. That course is definitely in need of some refreshment. 🙂 I’ll record a few videos for that per day and make my way through it in the month of June.

Do you know of any courses that can use some updated videos? Tweet at me @scottjduffy and I’ll be grateful for the tip.


And that’s it for issue 3.11. Thanks for reading this far. Talk to you again in two weeks.

What is your favorite platform to be on? Perhaps we can connect there.
