AZ-204 Developing Solutions for Microsoft Azure (Udemy.com)
The most complete course available on the Microsoft Azure developer exam AZ-204 with timed practice test.
Created by: Scott Duffy
Last updated December 2025
Our take
Based on the ratings of 34,821 students, a sample of their written reviews and the syllabus, as the course stood in December 2025. No course pays to be reviewed.
This is an exam-prep walkthrough for the Microsoft AZ-204 Azure Developer certification, taught by Scott Duffy. It runs about 8 hours across 93 lectures and 15 sections, covering App Service, containers, Functions, storage, Cosmos DB, authentication, encryption, Application Insights and messaging. It was published in 2016 and last updated in December 2025, and 189,472 students have enrolled. The natural audience is developers who already write .NET, Node or similar and want a guided tour of the exam topics.
Reviewers say Duffy explains things clearly and plainly, and about 86 percent of the 34,821 ratings are four or five stars. One reviewer calls the explanations crystal clear, another an excellent resource for getting started. The complaints are consistent, though. Lower-rated reviews say the depth falls short of the real exam, that most of the practice test content was not covered in the lectures, and that later sections feel rushed. One developer with four years of Azure experience says some services, such as storage queues, are explained inaccurately. Another found it a bit outdated against the test.
At eight hours it is short for an exam this wide, and the reviews suggest treating it as the first layer. Pair it with Microsoft's documentation, hands-on labs and a separate practice exam set. One reviewer also notes Microsoft is retiring AZ-204, so check the current exam status before paying. As an orientation, it works well. As the only thing you study, the low-star reviews say it will likely fall short.
Pros
- Reviewers describe Duffy's explanations as clear and easy to follow
- Covers the main exam areas in order: App Service, Functions, storage, Cosmos DB, auth and messaging
- Includes a practice test and 5 quizzes, which one reviewer says shows how to apply the knowledge
- Short at about 8 hours, so it works as a quick first pass before deeper study
Cons
- Many 1 to 3 star reviews say the depth is too shallow for the real exam questions
- Reviewers say practice test topics were not all covered in the lectures
- Some sections, such as Application Insights and messaging, are only a couple of short lectures
The explanations are very clear and the practice test is great as it introduces the application of the knowledge.
Labelled intermediate. Suits developers who code in .NET, Node or PHP and have at least some Azure exposure.
What you will learn
- Pass the Microsoft AZ-204 Developing Microsoft Azure Solutions test
- Master the main concepts of Azure, beyond the ones you normally use
- Become Microsoft Specialist: Developing Azure Solutions certified

Welcome to this course.
Fully captioned in English.
This course has been continually improved and covers the AZ-204 Azure developer topics.
Microsoft Azure is a skill in high demand in today's large business marketplace.
If you're a developer, you know as well as I do that change is always happening. It's not possible for all of us to be up-to-date on every piece of new technology out there, but this is not one of those times. Cloud-hosting has changed the way all applications are developed—from websites, to web applications, to mobile apps, and traditional backend applications as well. The rapid adoption of the cloud has touched everything.
The next time your resume is on someone's desk—be it a promotion at work or a new job opportunity—you cannot afford to have such an obvious gap in knowledge. Can you imagine being a front-end web developer today and not being able to talk about mobile-first or responsive design? Industry trends show that developing applications using cloud-hosted components is becoming the in-demand skill of tomorrow. Having Azure skills on your resume will only help you get in front of more hiring managers and land more jobs.
This course goes through all of the requirements of the Microsoft exam AZ-204: Developing Solutions for Microsoft Azure exam. While other online resources cover bits and pieces of the topic, I can confidently say this course goes deep on everything you need to know for this exam. Multiple videos are devoted to each sub-objective, and this course also includes a full sample test so you can see how ready you are to take the real test.
If you don't have much previous exposure to Azure, this course will cover each core section in detail. If you ARE already an expert at many Azure topics, you can easily skip the sections that you already know and focus on the sections that are new to you.
This Azure exam is tough. But these videos will guide you through the Azure interface, and through your own practice and experience with the platform.
You get lifetime access to the course, and so there are no silly "30-day" countdowns that require you to pay more to extend access. This course will be here when you need it.

Scott Duffy
Hi there, my name is Scott Duffy. And I love making complex technical topics easy to understand.
This has been the basis of my entire career – as a developer, as a development manager, as a software architect – over the past 20 years. I spend half my time in the world of business, explaining complex technical topics to business owners and stakeholders so that they can understand and agree with my approach to solving their business problems with technical solutions. And the other half with developers, explaining the business reasons behind decisions and ensuring that any decisions made on the technical side don't restrict the business in unexpected ways.
And I'm here on Udemy to teach what I know in an approachable way. I started teaching courses in 2014, and have taught over 1,600,000 students. I am grateful every day for being able to connect with so many students in almost every country around the world.
I'm a certified Enterprise Architect and certified cloud architect. I have been developing with Microsoft technologies for 20 years, starting with Classic ASP, and all the versions of .NET. We now live in the cloud era, with Microsoft Azure being prevalent in most large enterprises. I'm certified as an Azure Architect and Developer too. As well as AWS Solution Architect Associate (SAA).
Microsoft MVP Award winner for 2022-2025.

It’s an excellent resource for getting started; adding more intermediate test sections would make it even more helpful.
By Israel O. Nnaji on 4/13/2026
The explanations are very clear and the practice test is great as it introduces the application of the knowledge.
By John Fowler on 3/12/2026
A pretty good overview of the topics for the AZ-204 test. Biggest problem is that Microsoft just decided to retire AZ-204, and they haven't finalized its replacement yet, so the applicability of topics in this course is questionable for the long run.
By Arjun Viradia on 2/25/2026
The course covers major concepts of Az-204; However, I feel some concepts were missing after giving a try to a practice test. I had pursued this course in Feb 2026, and many things has changed with Azure Free subscription plan as compared to content of this course.
By Prabakaran on 2/15/2026
it's a good course. i'm really learned more from this coures. but one thing , i know only python programming language, but scott teachs use DOTNET language. this course did'n cover "Azure Redis and cashed" . if add that i'm fully satisfied. Thank you SCOTT DUFFY.
By Anonymized User on 1/24/2026
The course was good match for me because it focused on practical Azure development rather than just theory, The hands-on labs helped me understand how to build, deploy and manage application in Azure.
By ATHANASIOS GAZOS on 1/15/2026
There are some small details needed for doing the exercises, that are not explicitly mentioned in the lectures, BUT thinking how to solve them helped me own the knowledge shared in this course.
By Daejinkim on 1/13/2026
I passed az204 today with 722. so I appreciate this lecture. But I have to mention, the actual exam is way way way way more difficult than this lecture or MS learning practice tests. Hands on experience is required I think. I passed with not enough hands on experience, and studied theory hard for 7 days. Maybe that's why I felt it was harder than expected, but the actual questions were way trickier.
By Nikhil Munj on 1/5/2026
This course is very informative and detail oriented. It covers each and every topic related to Azure with great detail and the hands-on experience related to each topic is an added bonus. The course is long but i feel that’s the need when you are considering this level of expertise.
By Valentino Naicker on 12/22/2025
Information is covered in detail but without unnecessary detail so is productive use of learning time !
