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

Caching


Many times consumers request the same things, and the application returns the same information. In this scenario, caching is the solution to avoid constantly processing the same request and returning the required data faster.

Caching is used for data that does not change frequently in order to have a precalculated response without processing the request. The workflow is as follows:

  1. The first time that the consumer requests some information, the application processes the request and gets the required data.

  2. It saves the required data for that request in the cache with an expiration time that we define.

  3. It returns the data to the consumer.

Next time that a consumer requests something you need to do the following:

  1. Check whether the request is in the application cache and it has not expired.

  2. Return the data located in the cache.

So, in our example, we will use caching in the location microservice in order to avoid requesting the closest secrets multiple times.

The first thing that we need to use...
