PHP Microservices

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

Code versioning best practices


Over time, your application will evolve and, at some point, you will be at the point where you are wondering what you will do with the API of any of your microservices. You can keep the changes to a minimum and be transparent to the users of your API, or you can create different versions of your code. The best solution is versioning your code (API).

The well-known and commonly used ways for code versioning are as listed:

  • URL: In this method, you add the version of your API inside the URL of the requests. For example, the https://phpmicroservices.com/api/v2/user URL indicates that we are using the v2 of our API. We used this method in our examples throughout the book.

  • Custom request header: In this method, we do not specify the version in our URL. Instead, we use HTTP headers to specify the version we want to use. For instance, we can do a HTTP call to https://phpmicroservices.com/api/user, but with an extra header, "api-version: 2". In this case, our server...
