Question:
Which of the following AWS services can be used to automate the deployment of infrastructure and applications in AWS?
Options:
a. AWS Data Pipeline
b. AWS CloudFormation
c. AWS Backup
d. Amazon Glacier
Correct Answer:
✅ Option b: AWS CloudFormation
Explanation:
AWS CloudFormation is an Infrastructure as Code (IaC) service that allows users to automate the provisioning and deployment of AWS resources such as EC2 instances, VPCs, databases, IAM roles, and more. It uses JSON or YAML templates to define infrastructure as code, enabling consistent and repeatable deployments.
With AWS CloudFormation, users can:
- Deploy entire infrastructure stacks in an automated way.
- Maintain version control over infrastructure changes.
- Use Rollback and Change Sets for safer deployments.
- Integrate with DevOps pipelines for continuous deployment.
Why Other Options Are Incorrect?
❌ Option a: AWS Data Pipeline – This service is used for data processing and transfer between different AWS services and on-premises systems. It is not used for infrastructure deployment.
❌ Option c: AWS Backup – This service is used to automate backups across AWS services such as EBS, RDS, DynamoDB, and others. It does not manage infrastructure deployment.
❌ Option d: Amazon Glacier – This is a low-cost archival storage service used for long-term storage of infrequently accessed data. It does not handle infrastructure deployment.
Key Takeaways:
✅ AWS CloudFormation enables Infrastructure as Code (IaC) for automating AWS infrastructure deployment.
✅ It helps in managing, versioning, and rolling back infrastructure changes efficiently.
✅ Other services like AWS Data Pipeline, AWS Backup, and Amazon Glacier serve different purposes and are not used for infrastructure deployment.
