In this chapter, as the last chapter of this book, I tried to introduce microservices, an architecture style getting a lot of attention nowadays. We looked into it because we needed an architecture in which we can use RESTful web services to achieve better performance and scalability in complex and bigger systems.
The focus of the book was RESTful web services in PHP7, and we looked at other topics that were connected with building RESTful web services or PHP7 in someway. We looked at some of these topics in detail, whereas we just touched upon some others. Many of these topics are too broad to be contained in one chapter. Some of these topics can have a complete book dedicated to them. That's why, I provided different URLs towards learning material or suggested reading, which you can refer to if you are interested.
