Overview of this book

REST is the most wide spread and effective standard to develop APIs for internet services. With the way PHP and its eco-system has modernized the way code is written by simplifying various operations, it is useful to develop RESTful APIs with PHP 7 and modern tools. This book explains in detail how to create your own RESTful API in PHP 7 that can be consumed by other users in your organization. Starting with a brief introduction to the fundamentals of REST architecture and the new features in PHP 7, you will learn to implement basic RESTful API endpoints using vanilla PHP. The book explains how to identify flaws in security and design and teach you how to tackle them. You will learn about composer, Lumen framework and how to make your RESTful API cleaner, secure and efficient. The book emphasizes on automated tests, teaches about different testing types and give a brief introduction to microservices which is the natural way forward. After reading this book, you will have a clear understanding of the REST architecture and you can build a web service from scratch.

Chapter 9. Microservices

Although we discussed different aspects, what we have made is a RESTful web service for a simple blog in this book. We took that example to keep things simple in terms of business logic so that we can focus on our actual subject in detail. This was helpful, but in the real world, things are not that simple and small. There are big systems with different parts, which are difficult to maintain. These parts are also difficult to debug and scale. Scaling is different from just maintaining something and optimizing it for better performance. In scaling, optimization of both code and deployment environment matter. Scalability, maintainability, and performance have always been challenges that we have faced.

To handle this, we have an architectural style, known as microservices. So, in this chapter, we will discuss this. Microservices are not an essential thing to use. However, they solve some challenges that we often face while making RESTful web services for bigger systems...
