Overview of this book

The world is moving away from bulky, unreliable, and high-maintenance PHP applications, to small, easy-to-maintain and highly available microservices and the pressing need is for PHP developers to understand the criticalities in building effective microservices that scale at large. This book will be a reliable resource, and one that will help you to develop your skills and teach you techniques for building reliable microservices in PHP. The book begins with an introduction to the world of microservices, and quickly shows you how to set up a development environment and build a basic platform using Docker and Vagrant. You will then get into the different design aspects to be considered while building microservices in your favorite framework and you will explore topics such as testing, securing, and deploying microservices. You will also understand how to migrate a monolithic application to the microservice architecture while keeping scalability and best practices in mind. Furthermore you will get into a few important DevOps techniques that will help you progress on to more complex domains such as native cloud development, as well as some interesting design patterns. By the end of this book you will be able to develop applications based on microservices in an organized and efficient way. You will also gain the knowledge to transform any monolithic applications into microservices.

Preface

Event-driven architecture


Event-driven architecture (EDA) is a pattern of architecture for applications following the tips of production, detection, consumption of, and reaction to events.

It is possible to describe an event as a change of state. For example, if a door is closed and somebody opens it, the state of the door changes from closed to opened. The service to open the door has to make this change like an event, and that event can be known by the rest of the services.

An event notification is a message that was produced, published, detected, or consumed asynchronously and it is the status changed by the event. It is important to understand that an event does not move around the application, it just happens. The term event is a little controversial because it usually means the message event notification instead of the event, so it is important to know the difference between the event and the event notification.

This pattern is commonly used in applications based on components or microservices...
