Modern distributed systems promise scalability and flexibility, but building microservices that actually work in production is far more complex than most diagrams suggest. In this course, you’ll learn how to design, build, and operate .NET microservices on AWS using patterns and practices proven in real systems. We’ll explore the architectural decisions that matter most when moving from monoliths to microservices, including service boundaries, communication patterns, data ownership, resilience, deployment strategies, and operational trade-offs. You’ll also see how AWS services can be applied pragmatically to support .NET-based microservices, focusing on reliability, scalability, and production realities rather than theoretical architectures. This course is designed for experienced developers, architects, and technical leaders who want to move beyond simplified examples and understand how microservices work in real-world environments.
