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

Capacity planning


Capacity planning is the process of determining the infrastructure resources required by your application to meet future workload demands for your app. This process ensures that you have adequate resources available only when they are needed, reducing costs to the minimum. If you know how your application is used and the limits of your current resources, you can extrapolate the data and know, more or less, the future requirements. Creating a capacity plan for your application has some benefits, among which we can highlight the following ones:

  • Minimize costs and avoid waste from over-provisioning: Your application will use only the required resources, so it makes no sense, for example, to have a 64 GB RAM server for your database when you are only using 8 GB.

  • Prevent bottlenecks and save time: Your capacity plan highlights when each element of your infrastructure reaches its peak, giving you a hint about where the bottleneck can be.

  • Increase business productivity: If you...
