Infrastructure as Code with CloudFormation Flashcards
| Front | Back |
| How do you update a CloudFormation stack? | By submitting a modified template or by changing parameter values for an existing template. |
| How does CloudFormation handle failures during stack creation? | It rolls back all the resources that were created successfully to maintain the all-or-nothing nature of stack operations. |
| What are CloudFormation helper scripts? | A set of Python scripts that help install software and start services on EC2 instances. |
| What are the main sections of a CloudFormation template? | AWSTemplateFormatVersion, Description, Parameters, Mappings, Conditions, Resources, Outputs. |
| What is a change set in CloudFormation? | A preview of changes that would be made to a stack before actually implementing them. |
| What is a CloudFormation creation policy? | A policy that defines the actions CloudFormation should take if a resource fails to be created. |
| What is a CloudFormation custom resource? | A resource that enables you to write custom provisioning logic and integrate it with CloudFormation. |
| What is a CloudFormation deletion policy? | Specifies what happens to resources when a stack is deleted. |
| What is a CloudFormation stack set? | A feature that lets you create, update, or delete stacks across multiple accounts and regions with a single operation. |
| What is a CloudFormation stack? | A collection of AWS resources that you can manage as a single unit created from a CloudFormation template. |
| What is a CloudFormation template? | A JSON or YAML formatted text file that describes your AWS infrastructure. |
| What is a Mapping in CloudFormation? | A way to define conditional values that are evaluated at runtime based on parameter values. |
| What is a nested stack in CloudFormation? | A stack that is created as part of another stack using the AWS::CloudFormation::Stack resource type. |
| What is a parameter in CloudFormation? | A value that you can specify when you create or update a stack to customize resource properties. |
| What is a pseudo parameter in CloudFormation? | Predefined parameters provided by AWS CloudFormation (like AWS::Region or AWS::AccountId). |
| What is AWS CloudFormation? | A service that helps you model and set up your AWS resources so you can spend less time managing those resources and more time focusing on your applications. |
| What is CloudFormation Designer? | A graphic tool for creating, viewing, and modifying CloudFormation templates. |
| What is CloudFormation drift detection? | A feature that detects whether a stack's actual configuration differs from its expected configuration. |
| What is CloudFormation resource import? | A feature that allows you to bring existing resources into CloudFormation management. |
| What is CloudFormation rollback? | The process of restoring a stack to its previous working state if an update fails. |
| What is CloudFormation stack policy? | A document that defines the update actions that can be performed on designated resources. |
| What is Infrastructure as Code (IaC)? | A practice where infrastructure is provisioned and managed using code and software development techniques rather than manual processes. |
| What is the AWS CloudFormation Registry? | A managed repository of resource providers that define how CloudFormation provisions resources. |
| What is the AWS::Include transform? | A transform that allows you to reference template snippets stored in Amazon S3. |
| What is the benefit of using nested stacks? | They allow you to reuse common template patterns and manage complex architectures as modular components. |
| What is the DependsOn attribute in CloudFormation? | Specifies that the creation of a specific resource follows another. |
| What is the Fn::Sub function used for? | To substitute variables in an input string with values that you specify. |
| What is the intrinsic function Fn::GetAtt used for? | To get an attribute from a resource in the template. |
| What is the intrinsic function Ref used for in CloudFormation? | To reference a parameter or resource within a template. |
| What is the Resources section in a CloudFormation template? | The only required section that contains the definitions of the AWS resources you want to create with the template. |
