The ultimate Modular Monolith blueprint

I'm only halfway through the Modular Monolith Architecture course, but the value it provides is already exceptional. Milan explains complex architectural patterns with clarity and practical examples that can be applied immediately to production systems. Highly recommended for developers looking to build scalable and maintainable backend architectures.

This course is awesome. I learned a lot of new things. Thank you so much Milan

This course is perfect for anyone who has worked with both monoliths and microservices and wants to take the best from both worlds. I just finished Milan Jovanović’s Modular Monolith course, and it delivers exactly that — a clear, practical path to building modular systems that combine simplicity with scalability. Milan explains complex architectural concepts in a very approachable, hands-on way — from defining module boundaries and handling cross-cutting concerns to enforcing architecture and testing effectively. The section on reliable messaging, especially the Inbox and Outbox patterns, was my favorite — it really showed how to build resilient, event-driven systems without jumping straight into microservices. Highly recommended for engineers and architects who want to design clean, maintainable, and future-proof systems.

So much value on this course! No only Modular Monolith Architecture but so much more interesting topics. Highly recommended.

For me as a beginning software developer on ASP.NET Core and C# it is a very welcome course. The most important learning for me is that it bridges the gap between the theory in books about software architectural related principles and the practical implementation of those principles. It provides a very complete and well explained guide on how to apply these principles in a real world project.

This is an excellent course on building a modular monolith in .Net, the course progression is really well thought out, with a clear presentation of benefits and tradeoffs of the different options you have at certain stages. And the material is top quality. It also serves as a great compilation of various modern architectural patterns that are useful for a lot of situations, not only specifically for modular monoliths.

Learning modular monolith architecture will really sharpen my architectural skills and help us with our legacy migration plans. The Milan MMA course is packed with great content and hands-on examples that can guide us in building better, more maintainable software.

Before this course, my biggest challenge was managing a complex, monolithic application that was becoming increasingly difficult to maintain and scale. I was constantly battling with tight coupling and a lack of clear boundaries, which made adding new features a slow and error-prone process. The Modular Monolith Architecture course by Milan Jovanovic was a game-changer. It provided me with a clear, practical framework to solve these challenges. The information I gained will help me and my team to refactor our codebase, creating well-defined modules that are easier to understand, test, and evolve. The best thing about this course is its focus on real-world application. Milan's explanations are incredibly clear, and the examples are highly practical. I walked away with not just a theoretical understanding, but a solid plan to immediately improve our architecture. I highly recommend this course to any developer looking to build more maintainable and scalable applications.

I watched a lot of courses. Milan explains in a very simple, understandable way. I really like that in addition to the theory, he shows the code in practice. In addition to a detailed explanation of the concept of microservices and monolithic applications, I finally understood how to implement Keycloak in the application.

Definitely one of the best courses I’ve ever watched. It gave me so many solutions to problems I face every day while working on an old .NET legacy project with no architecture to speak of. Watching this course helped me gain a deeper understanding of C#, .NET, and software architecture in general. While I’m not able to fully apply everything in the projects I work on due to legacy requirements, the course has helped me solve dozens of issues I previously couldn’t resolve. It also highlighted some problems I didn’t even know existed! 😊 I would strongly recommend this course to anyone interested in software architecture and looking to improve their understanding of .NET.

The best software architecture course in .NET you can see. Milan has extensive knowledge of systems architecture accompanied by great communication skills. His way of explaining makes it very easy to understand each topic he addresses in this course.

I'm about 40% into this course and its really excellent so far. I am learning so much practical and extremely useful information (and, of course, code) that will be applied to production applications I am currently developing. Milan's course covers all aspects of Modular Monolith application development in a very clear, step by step way. I would highly recommend it to any .net core developer. Even if you're not planing to use the Modular Monolith approach, there is so much to learn and reuse in your projects.

I follow Milan for his YouTube videos and his way of explaining things, which instantly captivated me. So, as soon as I saw the opportunity to take one of his courses, I didn't hesitate. I know this course will greatly help me improve my career as a software engineer. It covers all the main topics I want to learn to develop my own project and apply them to my daily work as a developer, improving my skills and allowing me to create more professional products. The best thing about MMA architecture is that, when applied, we can create robust and scalable applications, without tight coupling and with simple implementation. Thank you, Milan, for this excellent course.

Before taking the Modular Monolith Architecture (MMA) course, one of my biggest challenges was working with desktop applications built in .NET that relied directly on Entity Framework Core, without a clear or scalable architecture. This made maintaining and evolving the applications quite difficult. Thanks to the course content, I’m now gradually migrating these systems to a much more robust, modular, and maintainable architecture. MMA is helping me unify design principles, properly structure my modules, and apply best practices that truly make a difference in the long run. What I value most about the course is how clearly complex concepts are explained and how they translate into practical solutions. It’s thoughtfully designed to address real-world development challenges. Without a doubt, it’s been a great investment.

I'm developing a relatively large project from scratch, and this architecture lets me break the project down into logical bricks without the constraint of microservices. I also intend to migrate a microservice project to this architecture. What I like about this architecture is that you get the advantages of microservice without the disadvantages, and for most projects that's more than enough.

I've never written a decoupled application that communicates via event messaging before. This course has turned out to be perfect! My favorite thing about this architecture is you can prepare your app for the future without excessive premature optimization. I will likely purchase more of Milan's courses.

I am the CTO of a SaaS Solution (ERP), and we are being challenged to integrate our legacy solutions with a lot of other partners' solutions. This course gives me the tools to implement ways to get it done.

This is a very detailed, comprehensive and highly relevant course for anyone in the .NET space working on business applications today. It covers theory with best practice implementations in .NET and related technologies with a very well-conceived case study that exposes numerous common software challenges. Modular Monolith Architecture is a sweet spot on a spectrum with ball-of-mud monolith at one end and many microservices at the other. At the heart of this approach are well defined modules and channels of communication between them. These structural elements define correct dependencies and promote loose coupling which ultimately provides software more capable of enhancement as business demands change. I thoroughly recommend taking this course to enhance your skills and technical proficiency.

I completed both PCA and MMA courses. I really enjoyed the content and the structure of these courses! It covers 100% back-end construction (design, coding and testing). I recommend these courses to anyone willing to learn how to create state-of-the-art applications with .NET!

In my work as a fresh Junior C# dev, it helped in many points regarding structuring services into separated modules and how to handle the communication in a module itself. For me personally I can listen very well to his voice and his explanation style, so to speak.

Exceptional value. The course bridges theory and practice by tackling real-world problems. I appreciate the in-depth explanation. I love Milan's straight-to-the-point flow. He provides a clear progression from basic concepts to production-ready solutions. At its price point, it's an outstanding investment for developers looking to build maintainable, scalable systems.

The modular monolith approach, as brilliantly explained by Milan, helps you build better software by promoting clear separation of concerns, making it easier to manage complexity, maintain code quality, and scale effectively. The best part is its balance of simplicity and flexibility, enabling teams to create well-structured, maintainable applications without the immediate overhead of microservices.

Up until now the course is amazing. Understanding how the modules boundaries should be defined, even if I've never had a professional experience with such architecture it's awesome to understand how this would be translated to microservices

Great explanation of the concepts! I really like the structure of this course. Additionally, I’ve learned about more tools that I can use in my daily work, such as Seq for log monitoring and Keycloak as an Identity Provider. With Keycloak, you don’t need to implement an Identity Provider yourself.

I just completed Milan Jovanovic’s Modular Monolith Course, and I really enjoyed the course and learned a lot. I’m very happy I took this course. I learned several new things, learned about what a modular monolith is, rules to adhere to, great patterns to re-use code between modules, communication, boundaries, event-driven architectures, and ways to break up and organize your Visual Studio solution. This course was well worth the time. I strongly recommend this to senior software engineers & architects that are new to modular monoliths, event-driven architecture, and clean architecture concepts. Thanks for this course, my skills and knowledge improved from taking this course.

MMA course really help me to generate better, readable and testible code.. also with the technic that milan teach for each and every concept of MMA. the only thing i found it hard to grasp is about RBAC which makes more complicated code. but i just repeat the video for sometime and finally get it. THANKS MILAN !

I've found immense value in this course on Modular Monolith Architecture. The clear explanations and practical guidance on module communication have been eye-opening. Understanding how to properly structure and connect modules has transformed my approach to building maintainable systems. Milan, thanks for this great job!!

Before this course, I struggled with defining clear module boundaries in my projects. The Modular Monolith Architecture (MMA) course solved this challenge completely, providing practical guidance on both boundary definition and asynchronous module communication. The course's focus on testing and module interaction was particularly valuable. Highly recommended for developers looking to master modular system design!

Well put together and provides great insights for building your own apps. It touches on everything you need and gives you a comprehensive foundation, along with Milan's Pragmatic Clean Architecture course, it's a great set of building blocks to work from. MMA provides a simpler approach that still provisions for evolving into micro services if the complexity becomes necessary. Keep up the great content Milan.

Milan is such a great instructor. I've been to a lot of online courses and none come close to this. The course will give you detailed and practical knowledge that you can apply to your actual work. No more hello world course. You'll be able to produce production ready products after learning from Milan!

This was by far the best course i have ever seen in software engineering. It is relevant for both beginners and seasoned veterans alike. I would highly recommend everyone to attend the course.

It's the second course I'm taking from Milan and I'm so excited about it. The way it's structured, the depth of each topic and the code is simply excellent. I have so many thoughts on how I will reuse this knowledge in my day-to-day work. This course is worth every penny I spent on it! Thank you, Milan!

The course is simply amazing, it has the facility to explain a complex subject in a simple and strongly technical C# oriented way. Milan approached the topics with an enormous ease, which allows you to absorb the knowledge very quickly. Therefore, I recommend it 100%.

As a senior software engineer, I found the "Modular Monolith Architecture" course by Milan to be transformative.

Whether you're a senior developer or just starting with MMA in .NET, it's a game-changer for anyone aiming to build robust applications.

As a C# developer with more than 20 years of experience, I can say without doubts that Milan's course on Modular Monolith Architecture is a must-have for both experienced and new developers. The course was incredibly well-structured, providing a comprehensive overview of the Modular Monolith approach and I am excited to apply these strategies to create scalable, maintainable, and efficient applications.

Using Modular Monolith Architecture (MMA) helps me build better software by improving maintainability, scalability, development speed, deployment simplicity, and overall system consistency. The best thing about MMA is its balance between simplicity and modularity. It offers the ease of managing a single app with the benefits of a modular setup. Plus, it makes transitioning to microservices later a breeze if needed. It's perfect for growing teams and projects, providing flexibility, maintainability, and scalability.

It was an extraordinary course. The way Milan introduces new concepts organically is simply remarkable. It helped me a lot in offering my clients more robust architectures with better practices, as well as enabling my team to internalize essential architectural concepts in modern back-end development.

As a SE who has been less hands on and more leadership lately this was an awesome course for getting back up to speed on both the dot net platform (which is now also awesome) as well as the latest patterns, practices, coding techniques in addition to the modular monolith concept in a practical format. This is the most real world course I have ever done. No Hello World, or ToDo list here, this is a serious full scale production application that you could take to market. I can't imagine how much time and effort went into creating this but it was worth it. To that point though, if you do this course you need to put in some serious time but as I said this is a serious course for those who are prepared to commit. TBH, I was not initially sure about the cost but now I am done I realise it would have taken dozens of other courses and lots of googling to get this real world knowledge. On Modular monoliths themselves, as someone who introduced microservices into a previous tangled monomess, I learnt some of the pitfalls so this midpoint idea makes perfect sense and you are not loosing anything as you can always split them. Thank you, Milan.

If you are a freelancer like me, or a software engineer at a tech company and you want to confidently recommend the Modular Monolith Architecture to your clients, get this course. It’s worth every penny.

I am immensely grateful for the opportunity to take this course. The level of expertise and depth of knowledge shared was truly exceptional.

I have been doing software for 30 years. This is one of the best courses that I have ever seen and the end result is phenomenal.

This is truly a master-piece course. Milan explained everything in details what you need to know to build a successful and well-designed Modular Monolith Application. I really enjoyed watching 12h+ of content. The quality of this course is on a top level. For sure this is the best Modular Monolith course you can find. The quality of this course is confirmed in the "10 - Microservices: Extracting Modules" chapter where a dedicated Module of the Monolith system is extracted into a seperate microservice in just one hour. I also like that this course is charged with so valuable information such as: writing tests, using OTEL, Jaeger and YARP. I definetely recommend this course for everyone who wants to learn how to build Modular Monolith applications, how to monitor the system, get the guidelines how to build a high quality software with a great design and testability. I can confirm that this course will be valuable for any level of developers, including seniors and lead devs.

Milan Jovanovic's MMA is an awe-inspiring course, the best I have taken.
