You can find providers for the cloud platforms and services you use, add them to your configuration, and then use their resources to provision infrastructure.

Providers contain all the code needed to authenticate and connect to a service-typically from a public cloud provider-on behalf of the user. Terraform providers are plugins that implement resource types. Modules can also be called multiple times, either within the same configuration or in separate configurations. A module can call other modules-called child modules-which can make assembling configuration faster and more concise. Writing even a very simple Terraform file results in a module. Terraform modules are useful because they allow complex resources to be automated with re-usable, configurable constructs. Terraform modules are small, reusable Terraform configurations for multiple infrastructure resources that are used together. Even better, previous configurations can be retained as versions to enable rollbacks if necessary or desired. Terraform provisions immutable infrastructure, which means that with each change to the environment, the current configuration is replaced with a new one that accounts for the change, and the infrastructure is reprovisioned. The danger with mutable infrastructure is configuration drift-as the changes pile up, the actual provisioning of different servers or other infrastructure elements ‘drifts’ further from the original configuration, making bugs or performance issues difficult to diagnose and correct.

Regardless of which cloud provider you use, it’s easy to find plugins, extensions, and professional support. Open source: Terraform is backed by large communities of contributors who build plugins to the platform.There are a few key reasons developers choose to use Terraform over other Infrastructure as Code tools: See “What is Infrastructure as Code?” for a closer look: Support experimentation, testing, and optimization: Because Infrastructure as Code makes provisioning new infrastructure so much faster and easier, you can make and test experimental changes without investing lots of time and resources and if you like the results, you can quickly scale up the new infrastructure for production.Prevent configuration drift: Configuration drift occurs when the configuration that provisioned your environment no longer matches the actual environment.With IaC, the resources are always provisioned and configured exactly as declared. Improve reliability: If your infrastructure is large, it becomes easy to misconfigure a resource or provision services in the wrong order.Improve speed: Automation is faster than manually navigating an interface when you need to deploy and/or connect resources.Infrastructure as code can help with the following: It’s a key component of Agile and DevOps practices such as version control, continuous integration, and continuous deployment. IaC allows developers to codify infrastructure in a way that makes provisioning automated, faster, and repeatable. To better understand the advantages of Terraform, it helps to first understand the benefits of Infrastructure as Code (IaC). If your organization plans to deploy a hybrid cloud or multicloud environment, you’ll likely want or need to get to know Terraform. It then generates a plan for reaching that end-state and executes the plan to provision the infrastructure.īecause Terraform uses a simple syntax, can provision infrastructure across multiple cloud and on-premises data centers, and can safely and efficiently re-provision infrastructure in response to configuration changes, it is currently one of the most popular infrastructure automation tools available. Terraform is an open source “Infrastructure as Code” tool, created by HashiCorp.Ī declarative coding tool, Terraform enables developers to use a high-level configuration language called HCL (HashiCorp Configuration Language) to describe the desired “end-state” cloud or on-premises infrastructure for running an application. This guide highlights everything you need to know about Terraform-a tool that allows programmers to build, change, and version infrastructure safely and efficiently.
