Introduction
What is Terraform?
Terraform is an open-source infrastructure as a code tool created by HashiCorp, that lets you provision, build, change, and version cloud and on-prem resources.
It lets you define both Cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share.
What is Infrastructure as Code?
Infrastructure as code (IaC) is the process that allows you to manage infrastructure with configuration files rather than through a graphical user interface.
IaaC allows you to build, change, and manage your infrastructure in a safe, consistent, and repeatable way by defining resource configurations that you can version, reuse, and share.
Why Terraform?
Manage any Infrastructure
Track Infrastructure
Reduce time to provision
Support multi-cloud Infrastructure deployment
Automate changes
Standardize configuration
Collaboration
How does Terraform work?
Terraform creates and manages resources on a cloud platform and other services through their APIs. Providers enable Terraform to work with virtually any platform or service with an accessible API.
Providers are a logical abstraction of an upstream API. They are responsible for understanding API interactions and exposing resources. Providers supported by Terraform, there are officially 130 providers supported by Terraform:
AWS
Azure
Google Cloud Platform
Kubernetes and so on
