*Terraform*

Terraform is an infrastructure as code tool created by HashiCorp that allows users to define, provision, and manage cloud and on-premises resources in a declarative configuration language. It enables automation of deployment and management of infrastructure across multiple cloud providers and services. Terraform's key features include declarative configuration, multi-cloud support, state management, plan and apply phases, modularity, and version control. To use Terraform, users write configuration files describing the desired infrastructure, initialize the working directory, and then run the plan and apply phases to provision the infrastructure. Terraform also allows users to tear down the infrastructure when it's no longer needed. Example use cases include automating cloud resource creation, managing Kubernetes clusters, setting up CI/CD pipelines, and enforcing consistent infrastructure across environments. Terraform is widely used by DevOps teams to manage infrastructure efficiently, reduce human error, and ensure reproducibility. It provides a versatile tool for hybrid or multi-cloud environments and enables collaboration and tracking changes over time. By using Terraform, users can simplify and standardize infrastructure configurations and reduce the risk of unintended modifications. Overall, Terraform is a powerful tool for managing infrastructure as code.
