What is Terraform

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.

Terraform 是一個開源的 Infrastructure as Code 工具. 由 HashiCorp 主導.

What is Providers

Providers are a logical abstraction of an upstream API. They are responsible for understanding API interactions and exposing resources.

一個Provider會提供某個雲端服務的Infrastructure as Code實作，當你需要使用整合不同的雲端時，只需要引入新的Provider，就可以在不同的設施之間進行整合。

HashiCorp官方透過和各家廠商合作，支援

  1. AWS
  2. GCP
  3. Azure
  4. Kubernetes

等等Providers

Why Terraform

Terraform允許工程師以程式碼(HCL or JSON)定義設施，這讓管理、新增、更改以及刪除設施更有安全、有效率
