Terraform

Question 1

What is Terraform?

Answer 1

Terraform is an open-source infrastructure as code (IaC) tool developed by HashiCorp. It allows you to define and provision infrastructure using a high-level configuration language. Terraform supports multiple cloud providers and services, enabling you to manage your infrastructure in a consistent and automated way.

Question 2

What are the key features of Terraform?

Answer 2

Key features of Terraform include:
Infrastructure as Code: Define infrastructure using declarative configuration files.
Execution Plans: Preview changes before applying them.
Resource Graph: Visualize dependencies between resources.
State Management: Keep track of infrastructure state to manage updates and changes.
Multi-Cloud Support: Manage resources across multiple cloud providers.

Question 3

How does Terraform handle state management?

Answer 3

Terraform uses a state file to keep track of the current state of your infrastructure. This state file is used to map real-world resources to your configuration, track metadata, and improve performance. The state file can be stored locally or remotely (e.g., in an S3 bucket) for collaboration.

Question 4

What is a Terraform provider?
