CQRS by Example. Master CQRS: Build Efficient and Scalable Systems with Real-World Examples

Carlos Buenosvinos, Christian Soronellas, Keyvan Akbary

This course offers an in-depth exploration of the Command Query Responsibility Segregation (CQRS) pattern, a powerful architecture design that separates read and write operations to achieve greater scalability and performance in software systems. You'll begin by understanding the core principles behind CQRS and why it is essential for handling complex, high-traffic applications. Throughout the course, we’ll work through real-world examples that demonstrate how to apply CQRS to achieve a cleaner and more efficient codebase.Next, we will guide you through the practical aspects of implementing CQRS in a variety of use cases, focusing on how it enhances system maintainability and performance. You'll learn to distinguish between commands and queries effectively, and how to manage data consistency across distributed systems using techniques like event sourcing and eventual consistency.By the end of the course, you will have a comprehensive understanding of CQRS and its benefits. You'll be able to implement it in your own projects, whether you're building new applications or improving legacy systems. With a focus on scalability, maintainability, and performance, this course equips you with the skills needed to take on complex architectural challenges confidently.

Domain-Driven Design in PHP. A Highly Practical Guide

Keyvan Akbary, Carlos Buenosvinos, Christian Soronellas

Domain-Driven Design (DDD) has arrived in the PHP community, but for all the talk, there is very little real code. Without being in a training session and with no PHP real examples, learning DDD can be challenging. This book changes all that. It details how to implement tactical DDD patterns and gives full examples of topics such as integrating Bounded Contexts with REST, and DDD messaging strategies. In this book, the authors show you, with tons of details and examples, how to properly design Entities, Value Objects, Services, Domain Events, Aggregates, Factories, Repositories, Services, and Application Services with PHP. They show how to apply Hexagonal Architecture within your application whether you use an open source framework or your own.
