What Are Microservices?

Autonomous, loosely coupled services

Microservices are an architectural style that structures an application as a collection of autonomous, loosely coupled services that are modeled around a business domain. Each microservice is focused on doing one thing well.

Owned by small, focused teams

A microservice is small enough that a single feature team can own it. Small team sizes promote greater agility. Large teams tend be less productive, because communication is slower, management overhead goes up, and agility diminishes.

Built and deployed independently

A team can update an existing microservice without rebuilding and redeploying the entire application, and roll back an update if something goes wrong. In traditional applications, a bug found in one part of the application, can block the entire release.


Why should I move to microservices?

Because your current monolithic system has grown so much that:

  • It takes forever to build and deploy such big system, even for small features or bug fixes
  • A small bug anywhere in the code can break the entire system, and it's not easy to roll back
  • Can't scale fast enough when needed and other times there are so many resources wasted all over the place
  • New team members strugle a lot trying to understand the entire code base

Who is using microservices?

Top companies that are constantly dealing with very complex changing requirements have been embracing microservices for several years.

Only microservices allow teams to stay agile and autonomous, while also getting your system ready to scale when unexpected traffic peaks show up.


Hi, I'm Julio!

I'm a passionate software engineer with almost two decades of experience building all sorts of applications and systems based on the .NET platform.

I like to continuously explore the latest software engineering trends and practices and use them to solve real world problems.

I believe reducing complex concepts into simple step by step instructions is incredibly valuable and helps to make coding accessible and fun for everyone.

This course teaches you WebApi, DI, new c# 9.0 functionalities, Docker, mongodb, microservices stuff and even some Postman stuff I wasn't aware of. Really went far beyond all my expectations. I did other individual courses about some of these topics (some considerably more expensive) and now I feel that most of these would not have been necessary had I watched this one first. Very likely the best programming course I ever did.

I really enjoyed this course. The content and pacing was just right for me as someone with C# experience but little microservices experience. Julio is really responsive to questions and has an engaging teaching style.

Amazing course content!! The structure and material make it easy to absorb and recreate. Thank you for bringing this out. Would be great if there is another course that would build on top of this to complete the entire application including the front end. Really look forward to it!!

I have watched Julio's free YouTube videos and learned a great deal there. I am looking to solidify what I have learned and continue learning more here. Halfway through and I am NOT disappointed! Finished it this morning and it was great! I cannot wait for Julio's next update.

What do I need to get started?

This is the only beginner level course on microservices and .NET. To get started all you need is:

  • Basic C# knowledge
  • Some web development experience
  • A computer with one of the most popular operating systems
  • A big desire to learn by doing

You don’t have to be an expert on anything since you will write every line of code from scratch and the course explains everything in great detail. No magic copy pasted code!
