Cosmos Down Under show 9 with guest Hugo Barona discussing migration is released

I had the great pleasure to get to also record another new Cosmos Down Under podcast last night. It's now edited and released.

Show 9 features Microsoft MVP Hugo Barona discussing his experiences in migrating clients to Azure Cosmos DB, and the lessons he's learned along the way.

I hope you enjoy it.

Service Principal vs Service Principle -> not the same thing!

I can't tell you how many times lately, that I've seen people writing about service principles when they really mean service principals. These are entirely different concepts!

I did a certification exam the other day, and it was asking about service principles. I was left wondering how many people had reviewed that before it was released.

But what's worse, is when people bake the wrong one into code libraries that others need to use. I was reading some content from Microsoft Learn: Quickstart: Manage data with Azure Cosmos DB Spark 3 OLTP Connector for API for NoSQL and I saw this code example:

Note the authType. I just thought it was a typo and was going to make a pull request to fix it. But then I went looking at the library that it was using. That's Azure Cosmos DB OLTP Spark 3 connector, and what amazed me, is that the typo was right throughout the library.

I've passed about this back to the Cosmos DB team but it left me wondering what you should do when you see this sort of error in a library.

Do you just use the typo in your code and just forever propagate the mistake?

What should library authors do, to avoid breaking existing code? Perhaps allow both the correctly spelled option as well as the wrong one?

Service Principal

A service principal is a security identity used by applications, services, or automated processes to access specific resources or perform tasks within an Azure Active Directory (Azure AD) tenant. It's most commonly a type of service entity that can be assigned permissions to access resources in a secure manner. These are very common in Azure but they appear in many places across the IT industry.

Service Principle

A service principle really isn't something we talk about often but if we did, it would be perhaps a rule that we try to follow when providing service. Richard Koch wrote a famous book called The 80/20 Principle. That's often called The Pareto Principle. Either way, it's got nothing to do with an identity that performs actions in IT systems.

 

 

Cosmos Down Under podcast 8 with guest Blaize Stewart is now published!

I recently noticed a blog post from Jay Gordon that was calling out interesting content from Blaize Stewart on antipatterns for development with Azure Cosmos DB.

I thought this would be a perfect topic for one of our Cosmos Down Under podcasts and Blaize agreed to take part.

So much content talks about what to do with a product, and even though everyone knows there are things you shouldn't do, very little content talks about these antipatterns. It was great to speak to Blaize about it, and to get his updated thoughts.

Cosmos Down Under podcast 7 with guest Rodrigo Souza is now published!

I was able to record another new Cosmos Down Under podcast today. My guest was Microsoft Senior Program Manager Rodrigo Souza.

In the show, we discussed the Change Data Capture feed for the Analytical store in Azure Cosmos DB. This is a powerful new capability and worth learning about.

I hope you enjoy the show.

Cosmos Down Under podcast 6 with guest Vincent-Philippe Lauzon is now published!

I published a new Cosmos Down Under podcast today.

In the podcast, I've discussed the new integration between Azure Cosmos DB and Azure Data Explorer with the program manager for the feature: Vincent-Philippe Lauzon.

It's a great new capability and worth half an hour of your time to find out about it.

I hope you enjoy it. You'll find it, along with all Cosmos Down Under podcasts at: https://podcast.cosmosdownunder.com
