AWS Certified Cloud Practitioner

AWS CloudFormation is an Infrastructure as Code (IaC) service that allows users to model and provision AWS resources in a predictable and repeatable manner. It enables users to create templates that describe the AWS resources needed for their applications, and then CloudFormation takes care of provisioning and configuring those resources automatically. This eliminates the need for manual resource creation and ensures consistent deployments across different environments.

Key benefits of AWS CloudFormation:

• Infrastructure as Code: Define infrastructure using JSON or YAML templates
• Automated Provisioning: Automatically creates and configures resources
• Consistency: Ensures identical deployments across environments
• Version Control: Templates can be version-controlled like application code
• Dependency Management: Automatically handles resource dependencies
• Rollback Capabilities: Can automatically roll back if deployment fails

The other options describe different AWS services:

• Option A: AWS Lambda or AWS SDKs support application coding
• Option B: Amazon CloudWatch monitors the cloud environment
• Option C: AWS Security Hub or AWS Config help with threat response automation
