Course Description

The goal of this course it to equip you with all the knowledge required to design a robust, highly scalable microservices architecture. 

If you know nothing about Microservices, this course is ideal for you! You will get a fast, yet comprehensive introduction into the world of microservices!

Upon completion of this course, you will know how to manage data and distributed transactions in a microservices-based system. You will also learn how to secure microservices, and how microservices interact with each other through asynchronous event-driven communication while maintaining autonomy and independence.

At the conclusion of this course, you will learn how to convert a monolithic application into microservices.


What students are saying about this course?

5-Stars: By far one of the most concise explanations of microservices that I've heard so far. This was a great introduction and the sections helped to fill in some knowledge gaps about the tools that I've been using. A great breakdown of the "what" and "why" of microservices - Miguel Malcolm

5-Stars: Simple and easy to understand introduction but high level approach to microservices architecture. I will recommend this to any one who wants to get into microservices architecture. - Michael Gyekye

5-Stars: Brilliant course. Great overview of what constitutes a microservices architecture. Well done Sean. - Akoni Tee

5-Stars: Concentrated information about all aspects of microservice architerture - Vyacheslav Kolotiy

5-Stars: Great course for understanding Microservices principles. - Andrew Rosenbaum

5-Stars: Excellent starter course. Great overview of microservice. - Ann

5-Stars: Exactly at the level of detail I was looking for. It kept it high level at the architectural level, while going into enough detail to touch on the key architectural concepts. It's a great class to get oriented in the space and the reading list at the end is very helpful. Thank you for making this class. - Peter Cordone

5-Stars: Very Simple, to the point. A full meal of microservices explained very neatly in a short time. Highly recommend for any who wants to start working on microservice or already working on microservice to learn some new patterns and technologies. - Raghavendra Shapur Chandraiah Setty

The role play in the introduction section was terrible. We had barely gotten passed high-level bullets about microservices and then there was a timed conversation to try to convince an AI CTO to start using microservices? Very frustrating.

By Jose Manuel Marin Merlos on 4/18/2026

It helps me to get a overall and technology independent view of a microservice architecture

By Gonçalo dos Prazeres on 4/15/2026

Good, well-structured overview of the domain. However, it lacks in-depth detail regarding the technologies and methodologies needed to become truly proficient. I would have liked more focus on refactoring monoliths.

By Danilo Alves on 4/14/2026

Excelente curso para dar um panorama geral e bem completo sobre criarmos sistemas distribuidos altamente escaláveis usando arquitetura de microserviços. Mesmo não tendo um exercício para praticar, o curso entrega um conteúdo muito completo que te deixa bem orientado nos próximos passos a seguir.

By Ashish Kumar on 3/28/2026

Great course. Giving a bird's eye view of microservices landscape. While other course jump into code, which makes microservices sound like a huge sea of just tools.

By Greg Reding on 2/9/2026

The course is labeled for beginners, but at this point it is presenting some topics that I am unfamiliar with.

By Sarvesh Tripathi on 1/19/2026

Very nice course which help to understand whole architecture of Micro services. It cleared my concepts on CQRS and SAGA pattern very well.

By Anonymized User on 12/22/2025

I love this short course as it gives me all the info needed for a beginner to read more in-depth about Microservices. Thank you!

By Michiel Brand on 12/15/2025

This course was perfect for what I needed - an overview of microservice systems. This knowledge gives me the head start I need for a deeper dive and hands-on implementation.

By Asep Hikmat Fatahillah on 10/27/2025

amazing overview of a microservice but it is a lot to take in even for a software developer

By Eydar Gregorio Del Angel Davenport on 11/21/2020

It was amazing, my recommendation to improve is add more content.

By Jack Speir on 11/14/2020

Good informative content
Slides were too densely packed, often presenter just read off of them.
