Foreword
Cloud computing has transformed the way applications are built and delivered. In the early days of
the public cloud, the services available were generally low-level infrastructure. Today, the
hyperscalers provide a broad range of services, including specialized data stores, application
middleware, and many compute platforms for virtual machines, containers, and functions.
Applications can be quickly built by composing together services. Scaling with demand becomes
totally elastic without complex capacity planning.
While building applications is easier, our infrastructure is now more complex than ever. Infrastructure
as Code is broadly adopted to manage the complexity of cloud infrastructure by allowing users to
simply codify the resources required to support their application. HashiCorp Terraform is the de facto
standard for Infrastructure as Code, driven by an extensible ecosystem that supports thousands of
integrations spanning public cloud providers, Software as a Service (SaaS), hardware systems, and
more.
This new book on Terraform provides a pragmatic, hands-on approach covering real-world scenarios.
The author, Mark Tinderholt, deeply understands cloud environments as a principal architect at
Microsoft Azure. For readers new to Terraform, the book provides a foundational overview to
understand Terraform, the HashiCorp Configuration Language (HCL), and how to use the
extensible providers. From there, the author covers the key concepts needed for cloud-based
applications and patterns such as GitOps and CI/CD.
Going from the basic concepts, the author then dives into real-world examples of using Terraform to
manage virtual machines, containers, and functions across AWS, Azure, and GCP. This takes the core
, concepts and applies them, to enable you to quickly do the same. This hands-on approach enables
you to better understand how to apply Terraform outside of simple examples.
The book ends by providing guidance on best practices in production environments, how to adopt
Terraform for existing infrastructure using the import mechanisms, and finally, how to continue
learning through Terraform certifications. There are multiple levels of Terraform certifications, with
tens of thousands of people certified. The certifications are useful both to test your knowledge and
competence with Terraform and to share with prospective employers.
This book is a great resource for anybody hoping to learn more about Infrastructure as Code with
HashiCorp Terraform and quickly get an understanding of how to use it to build applications in the
major cloud providers. The author brings a depth of understanding as a senior engineer with a first-
hand understanding of how cloud providers are built, having spent years working with Terraform.
