Does this sound familiar?

In the early days of your project, everything was great: the small code base was easy to understand, you could add features and fix bugs quickly, you could verify the whole app was working properly with just a few manual tests and you were able get a new version up and running any time your boss asked to show your progress.

A year later, your customers are loving your app, but now that your team has grown and you have to deal with thousands of lines of code, things are not fun anymore:

  • The code base is too complex to understand and explain to new team members, which makes adding new features and fixing bugs difficult and time consuming
  • Loading and building the code in your IDE keeps getting slower. It's painful to make even one-line changes
  • The app keeps breaking very frequently now that there are so many devs making changes at the same time. Even a small bug in a single module can break the whole thing
  • You keep missing deadlines. With so much to build and test, you can only release new bits once a month, and usually late on a Friday or Saturday night
  • Scaling to handle the increasing load is too hard. Getting new servers, configuring them, deploying your app there, etc. And when the load goes down, so much wasted server power.
  • Move to the latest .NET stack? Only a dream. It would mean rewriting a crazy amount of code, not to mention the time needed to verify all features keep working properly and reconfiguring your production environment for the latest tech

There must be a better way, right? After reading a few blog posts and watching some YouTube videos, you realize you are suffering from a case of monolithic hell, and you keep hearing that the way to get out of this mess is to adopt a microservices architecture.

What Are Microservices?

alternative
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.

alternative
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.

alternative
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.

What others are saying

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.
Nathan Waterman
alternative
Amazing course I'd recommend anybody who wants to quickly grasp the fundamentals of microservices based on the .NET stack in a very practical way. There's no fluff material and the content itself is structured pretty well.
Samuel Tóth

It's a perfect course to learn the basics of microservices. Also, great introductory to learn Docker, Mongo Db and Message Brokers. It's clear and easy to understand.
Alper Tunga
alternative
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.
