CloudFormation
CloudFormation is Amazon's tool for setting up and managing cloud resources automatically. Think of it like a blueprint system for building in the cloud - instead of manually creating servers, databases, and other cloud components one by one, CloudFormation lets developers write a single plan (called a template) that builds everything automatically. It's similar to other tools like Terraform or Azure Resource Manager. This saves time, reduces mistakes, and helps keep cloud setups consistent. When you see this on a resume, it means the person has experience with automating cloud infrastructure on Amazon Web Services (AWS).

Example Interview Questions
Senior Level Questions
Q: How would you manage multiple environments (development, staging, production) using CloudFormation?
Expected Answer: A senior candidate should explain how they use template parameters, multiple stacks, and nested stacks to maintain different environments efficiently while keeping configurations consistent and secure.
Q: What strategies do you use for managing large-scale infrastructure with CloudFormation?
Expected Answer: They should discuss organizing templates into reusable components, version control practices, testing strategies, and how they handle updates and rollbacks across multiple services.
Mid Level Questions
Q: How do you handle secret management in CloudFormation templates?
Expected Answer: Should explain using AWS Secrets Manager or Parameter Store, avoiding hardcoded sensitive information, and proper practices for managing different types of configuration data.
Q: Can you explain how you would troubleshoot a failed CloudFormation deployment?
Expected Answer: Should describe checking stack events, looking at logs, understanding rollback processes, and common issues that cause deployments to fail.
Junior Level Questions
Q: What is a CloudFormation template and what are its basic components?
Expected Answer: Should explain that a template is like a blueprint that describes the AWS resources you want to create, and mention basic parts like resources, parameters, and outputs.
Q: What's the difference between a CloudFormation stack and template?
Expected Answer: Should explain that a template is the instructions file that describes what you want to build, while a stack is the actual set of resources that gets created from that template.
