Terraform best practices emphasize reusable modules, semantic versioning, Terraform state management, collaboration, and protecting sensitive information. In practical terms, this includes automating network configurations and application deployments, managing environments, refactoring monolithic deployments to a more module-based infrastructure, and using no-code modules where feasible. In this course, you will explore how to apply best practices by automating network configurations and managing application load balancers to deploy scalable and highly available applications. You'll discover how to refactor configurations from a monolithic to a more modular design and leverage the moved block to avoid potential service disruptions. After course completion, you will be able to apply Terraform best practices including the automation of network configurations and the deployment of scalable and highly available applications.
