Microservices Architecture: Practical Guide (بالعربي)Microservices Architecture: Practical Guide (بالعربي)

This course takes you on a deep dive into the world of distributed systems and microservices architecture, exploring not just the theory but also the real-world challenges and practical solutions.

We start with the Fallacies of Distributed Systems, one of the best ways to understand the hidden problems of distributed environments and why most of us unknowingly design systems as if these problems don't exist. This sets the stage for everything that follows.

From there, we move into Microservices Architecture, what it really is, why it became a trend, who made it popular, and the real reasons behind its rise. You'll learn the advantages, the pitfalls, and most importantly, when and how to adopt it. We'll discuss team readiness, organizational needs, and the key factors that determine whether microservices are the right choice for your company. You'll also explore strategies for both greenfield and brownfield projects, how to measure the effectiveness of your architecture, and patterns like the Strangler Fig for incremental migration.

Next, we dive into communication in microservices, covering different styles and integration patterns, service discovery and registration, and the roles of API Gateways and BFF, when and how to use them effectively.

A dedicated section explores coupling, showing how a deep understanding of different coupling types can guide better design and help you choose the right integration style for your system.

We then tackle one of the most critical and risky areas: Fault Tolerance and Resiliency. You'll learn why cascading failures happen, why they're a nightmare at scale, and how to apply proven patterns like Timeouts, Bulkheads, Retries, Circuit Breakers, Death Spiral protection, Metastable failure handling, Load Shedding, and more to build resilient systems.

The course also covers data and transactions in microservices, including patterns like Materialized Views, CQRS, Event Sourcing, Distributed Transactions, and the Saga Pattern (both choreography and orchestration). You'll see practical examples of when and how to use each approach.

This course is designed to be deep and comprehensive, covering the essential concepts, patterns, and pitfalls every engineer should know when working at scale. Since it's built on live courses, you'll also benefit from a wealth of real-world Q&A, where we address misconceptions, fill knowledge gaps, and share insights from challenges engineers face in different contexts.

By the end of this course, you'll not only understand microservices architecture in depth, but you'll also gain the practical tools and mindset needed to design, build, and operate resilient, scalable systems in the real world.
