Introduction

In this chapter, we'll describe complete infrastructures using Terraform, how it looks when everything is tied together, with a real project in mind. Most examples from previous chapters on Terraform were on Amazon Web Services, so to try to be more diverse and complete, this chapter is dedicated to other infrastructure services, namely Digital Ocean, Google Cloud, Heroku, and Packet. On Digital Ocean, we'll build a fully working and monitored CoreOS cluster with DNS dynamically updated. On Google Cloud, we'll build a three-tier infrastructure with two HTTP nodes behind a load balancer and an isolated MySQL managed database. Using OpenStack, we'll deploy a GitLab CE and two GitLab CI runners, using different storage solutions. We'll see how we can integrate and automate a Heroku environment. We'll end this chapter with a powerful and scalable Docker Swarm cluster on bare metal using Packet, capable of scaling hundreds of containers.
