Using an Azure Managed Identity to authenticate on a different App Service

A couple of weeks ago, I was tasked to implement authentication between the services we have in our Azure landscape. I knew this can be done by using the Managed Identity, as we were doing this on a project I was involved with in the past. However, I had never actually done this myself. Most of the time the System Administrators were configuring everything and I just had to copy-paste some Guids in a configuration file. Read more →

First steps into logging of your Azure Functions

Creating a solution with multiple small services is great of course. It provides you with a lot of flexibility and scalability. There are however a couple of things you have to think about when designing and developing a solution with multiple services. One of the things you need to figure out is how to implement proper logging. For an actual production system you need to have this in place in order to monitor and debug the overall solution.

Starting with Azure Functions

Lately, I've been busy learning more about creating serverless solutions. Because my main interest lies within the Microsoft Azure stack I surely had to check out the Azure Functions offering. Azure Functions enable you to create a serverless solutions which are completely event-based. As it's located within the Azure space, you can integrate easily with all of the other Azure services, like for example the service bus, Cosmos DB, storage, but also external services like SendGrid and GitHub!

What's up with this serverless talk?

You've probably heard a lot of talk around a new buzzword serverless. It's a pretty confusing name for an awesome technology/technique. The main reason the word serverless isn't a very good one is because it implies there aren't any servers when using this technique. I found a fairly funny CommitStrip about this topic. https://www.commitstrip.com/en/2017/04/26/servers-there-are-no-servers-here` But what does the term mean then? Well, it means you don't have to worry about servers anymore. Read more →

Designing a microservices architecture

There are dozens of blog posts, articles and books talking about microservices. Some of them talk about the design, other on how to implement and even others talk about why and when to use them. This post will be a combination of them all. I won't claim to be the all-time-expert on the matter, but I have read quite a bit on the subject, attended some talks and have had the honor to design (and implement) such a solution a couple of years ago.
