Overview of this book

The Infrastructure as Code (IaC) approach ensures consistent and repeatable deployment of cloud-based IaaS/PaaS services, saving you time while delivering impeccable results. Infrastructure as Code for Beginners is a practical implementation guide that helps you gain a clear understanding of the foundations of Infrastructure as Code and make informed decisions when implementing it. With this book, you’ll uncover essential IaC concepts, including planning, selecting, and implementing the right tools for your project. With step-by-step explanations and real-world examples, you'll gain a solid understanding of the benefits of IaC and the scope of application in your projects. You'll learn about the pros, cons, and best practices of different IaC tools such as Terraform and Ansible, and their use at different stages of the deployment process along with GitHub Actions. Using these tools, you'll be able to design, deploy, and secure your infrastructure on two major cloud platforms, Microsoft Azure and Amazon Web Services. In addition, you'll explore other IaC tools such as Pulumi, AWS CloudFormation, and Azure Bicep. By the end of this book, you’ll be well equipped to approach your IaC projects confidently.

Summary

In this chapter, we did a deep dive into using Terraform to deploy our WordPress environment in Microsoft Azure. We discussed the Terraform providers and worked through the Terraform code before finally executing it.

Also, as part of this walkthrough, we discussed some of the considerations you need to make when looping through resources, when it’s appropriate to use depends_on, and how we can use templates to generate content.

Next up, we walked through the Ansible code, which deploys the same set of resources. This time, rather than a deep dive, we only went into detail on the Azure-specific details, as we will take a closer look at Ansible in Chapter 5, Deploying to Amazon Web Services.

Everything we covered so far should hopefully start to get you thinking about how you can apply some of the subjects we have covered to your own Infrastructure-as-Code deployments and you should already be starting to get a feel for which of the two tools you prefer.
