Interview Questions

What is the main purpose of AWS Systems Manager?

AWS Systems Manager allows you to centralize operational data and automate tasks across your AWS resources. It helps in maintaining security and compliance by scanning your instances against your patch, configuration, and custom policies.

What is AWS CloudFormation mainly used for?

AWS CloudFormation provides a common language for you to model and provision AWS and third-party application resources in your cloud environment. You can use AWS CloudFormation to automate and simplify the provisioning and management of your cloud resources.

What is the difference between AWS Systems Manager and AWS CloudFormation?

AWS Systems Manager is particularly strong for task automation, patch management, and configuration management. AWS CloudFormation, on the other hand, is mainly aimed at providing infrastructure as code services, allowing developers to design and setup AWS resources using template files.

What is the concept of ‘Infrastructure as Code’ that is provided by AWS CloudFormation?

Infrastructure as Code (IaC) is a practice in which infrastructure is managed and provisioned through machine-readable definition files, rather than hardware configuration or interactive configuration tools. AWS CloudFormation embraces this concept by enabling developers to manage and provision AWS infrastructure using JSON or YAML formatted scripts.

Are AWS CloudFormation Templates region-specific?

No, AWS CloudFormation templates are not region-specific. They can be used to create stacks in any region that the AWS services or resource types specified in the templates are available.

How can AWS Systems Manager assist in managing EC2 instances at scale?

AWS Systems Manager features a powerful tool known as Run Command, utilizing which you can safely automate common and repetitive tasks across groups of EC2 instances. You can also set up recurring schedules for administrative tasks with Maintenance Window.

How does AWS CloudFormation handle updates to AWS resource stack?

When you update a stack, AWS CloudFormation generates a change set, a summary of your proposed changes. You can preview the changes, including how they impact your existing resources, before implementing them.

How can you troubleshoot automation workflows in AWS Systems Manager?

AWS Systems Manager provides a visual console for troubleshooting and evaluating the execution history of an automation workflow. You can see step-by-step details, allowing you to pinpoint the causes of failures.

Can AWS CloudFormation templates be re-used?

Yes, AWS CloudFormation templates can be re-used as they are JSON or YAML-formatted text files. Therefore, they can be managed in source control systems, edited with text editors or IDEs and can be used across different AWS accounts.

What types of data can AWS Systems Manager Parameter Store manage?

AWS Systems Manager Parameter Store can manage plain-text data such as database strings as well as secrets such as passwords, database strings, and license codes. Secrets can be encrypted with AWS KMS keys.

How does AWS CloudFormation ensure idempotency during stack creation or update?

AWS CloudFormation ensures idempotency by treating each stack operation, such as creating, updating, or deleting a stack, as a distinct action. If you try to perform the same action multiple times, the result will always be the same.

What is AWS Systems Manager State Manager?

AWS Systems Manager State Manager is a feature in Systems Manager that automates the process of keeping your EC2 and hybrid infrastructure in a state defined by you. This can be used to maintain consistent security configurations and update software regularly.

How does AWS CloudFormation handle rollbacks during stack operation failures?

During a stack operation, if any AWS resource defined in the AWS CloudFormation template cannot be created or updated, AWS CloudFormation rolls back the entire stack operation to a previously known stable state.

How can AWS Systems Manager help maintain software compliance?

AWS Systems Manager Inventory provides visibility into your software portfolio by tracking detailed system configuration, OS patch levels, application installations, and configuration of the AWS services and software deployed on your Amazon EC2 instances.

Can AWS CloudFormation work with other DevOps tools?

Yes, AWS CloudFormation can work with other DevOps tools. For example, you can use Jenkins or AWS CodePipeline for Continuous Integration and Continuous Delivery (CI/CD) and AWS CloudFormation for infrastructure provisioning.
