Overview of this book

NGINX Cookbook covers the basics of configuring NGINX as a web server for use with common web frameworks such as WordPress and Ruby on Rails, through to utilization as a reverse proxy. Designed as a go-to reference guide, this book will give you practical answers based on real-world deployments to get you up and running quickly. Recipes have also been provided for multiple SSL configurations, different logging scenarios, practical rewrites, and multiple load balancing scenarios. Advanced topics include covering bandwidth management, Docker container usage, performance tuning, OpenResty, and the NGINX Plus commercial features. By the time you've read this book, you will be able to adapt and use a wide variety of NGINX implementations to solve any problems you have.

Powering API Gateways with OpenResty

In our previous recipe, we explored a basic microservice to look up DNS records. While this can be limited per service to prevent abuse, ideally, we want to configure a centralized point to manage this. Otherwise, any limits across multiple services will not be considered as a whole and will need to be individually implemented per service. The following figure explains the differences:

To build a centralized API gateway, we need to consider the following points:

  • Authentication
  • Request routing
  • Rate limiting
  • Load balancing
  • Security
  • Logging

This recipe will cover a basic implementation of an API gateway to get you started with some of the core concepts. Because of the ease of implementation, it provides a rapid way to get started with the management of a few, small microservices.
