Advancements made in cloud technology and automation tools have led to increased challenges in defining and managing your infrastructure or app environment as code on your chosen cloud platform, integrating security, managing microservices complexity, and so on. This book takes a learning-by-doing approach to teach you how to employ Terraform features to develop efficient cloud infrastructure using real-world scenarios and best practices. The book begins by introducing you to Terraform's architecture, both as a command-line tool and a programming language, HashiCorp Configuration Language (HCL). You’ll discover best practices, usage, and architectural patterns and implement Terraform on virtual machines (VMs), Docker/Kubernetes, serverless, and multiple cloud platforms such as AWS, Azure, and GCP. The chapters also show you how to industrialize your CI/CD pipeline by integrating Terraform with other popular technologies to build, provision, deploy, and manage cloud infrastructure. You’ll gain a clear understanding of security, monitoring, troubleshooting, and cost optimization and be able to apply the concepts you’ve learned when preparing for Terraform Associate certification exams. By the end of this book, you’ll be equipped to confidently build, automate, and deliver your infrastructure and CI/CD pipelines in cloud-based applications.
