How does Terraform work?

[mstakh.i.mom.i]

HashiCorp Terraform is an infrastructure-as-code tool that lets you define both cloud and on-premises resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to deploy and manage the entire infrastructure throughout its lifecycle. Terraform can manage low-level components such as compute, storage, and network resources, as well as high-level components such as DNS records and SaaS functions.


Terra-form creates and manages resources on cloud platforms and other services through retail email list its application programming interfaces (APIs). Providers allow Terra-form to work with almost any platform or service with an available API. HashiCorp and the Terra-form community have already written over 1,700 providers to manage thousands of different types of resources and services, and the number continues to grow. You can find all public providers in the Terra-form registry, including Amazon Web Services (AWS), Azure, Google Cloud Platform (GCP), Kubernetes, Helm, GitHub, Splunk, DataDog, and many more.

The core Terra-form workflow consists of three phases:
Entry: You define resources that can span multiple cloud providers and services. For example, you can create a configuration to deploy an application to virtual machines in a Virtual Private Cloud (VPC) network using security groups and a load balancer.
