Recall & Review

beginner

What is AWS CloudFormation?

AWS CloudFormation is a service that helps you create and manage AWS resources using templates written in JSON or YAML. It automates resource setup in a safe and repeatable way.

What is Terraform?

Terraform is an open-source tool that lets you define and manage infrastructure across many cloud providers using a simple configuration language called HCL (HashiCorp Configuration Language).

Name one key difference between CloudFormation and Terraform.

CloudFormation works only with AWS services, while Terraform supports many cloud providers like AWS, Azure, Google Cloud, and others.

How do CloudFormation and Terraform handle state management differently?

CloudFormation manages state automatically within AWS. Terraform keeps state in a separate file that you can store locally or remotely, which helps track resource changes.

intermediate

Why might someone choose Terraform over CloudFormation?

Because Terraform supports multiple cloud providers and has a simpler, more flexible language, it is often chosen for managing infrastructure across different clouds or for more complex setups.

Which tool is limited to managing only AWS resources?

A CloudFormation

B Terraform

C Both

D Neither

CloudFormation is designed specifically for AWS, while Terraform supports multiple cloud providers.

What language does Terraform use for its configuration files?

A JSON

B HCL

C XML

D YAML

Terraform uses HCL (HashiCorp Configuration Language), which is designed to be easy to read and write.

How does CloudFormation store its state information?

A In a remote database you must configure

B In a local file

C Automatically managed within AWS

D It does not store state

CloudFormation manages state automatically inside AWS, so users don't have to handle state files.

Which tool is better suited for managing infrastructure across multiple cloud providers?

A Terraform

B Both are equally suited

C CloudFormation

D Neither supports multi-cloud

Terraform supports many cloud providers, making it ideal for multi-cloud environments.

Which of the following is a benefit of using Infrastructure as Code tools like CloudFormation or Terraform?

A Requires no learning

B Manual setup of resources

C Only works with virtual machines

D Automated, repeatable resource management

Infrastructure as Code tools automate and make resource management repeatable and consistent.

Explain the main differences between AWS CloudFormation and Terraform.

Think about provider support, state management, and configuration language.

Describe why someone might choose Terraform instead of CloudFormation for their infrastructure projects.

Consider project scope and tool flexibility.
