Microservices are often viewed as a silver bullet, but real-world experience tells a different story. In this presentation, I will take you through a journey of both successful and failed large scale microservices implementations I have been part of over the past decade. We will explore how microservices can either simplify or drastically complicate a project, potentially turning it into a nightmare for developers.

This presentation will focus not only on the technical aspects of the architecture, such as dealing with distributed transactions or the challenges of excessive services communication, but also on the often-overlooked need for an organizational shift - adjusting processes and embracing a new mindset. You'll learn what to do and what to avoid to ensure that your microservices journey delivers on its promise of agility and scalability, rather than becoming a complex and overwhelming challenge. All of this is based on real-life examples from various projects of different scales, ranging from monolith to microservices migrations, to managing microservices on a scale of thousands of services.
