Drift Detection
Drift Detection is a feature in AWS CloudFormation that allows you to detect if the actual stack resources have drifted from the expected stack configuration, as defined by the stack template and applied parameters. Drift is any unintentional change in the stack resources made outside of CloudFormation that leads to discrepancies between the actual and expected stack configuration. By using the drift detection feature, you can identify resources that have drifted, view what has changed, and take necessary actions to remediate the drift, such as updating the template or resources. This helps maintain consistency, compliance, and version control of your infrastructure, ensuring it adheres to the intended configuration.
A Comprehensive Guide on Drift Detection for AWS Solution Architect Exams
Drift Detection is a feature provided by AWS CloudFormation. Its importance lies in the fact that it helps AWS users track possible configuration changes made to stack resources out-of-band i.e, alterations that occur outside of CloudFormation.
Why is it important?
Drift Detection boosts security, reduces debugging time, and assists in understanding stack templates and resources, promoting overall AWS infrastructure health.
What is Drift Detection?
It's an AWS CloudFormation feature enabling users to identify if stack resource properties have drifted, or deviated, from their expected configurations.
How does it work?
Drift detection compares the current stack resource properties with the expected properties defined in the stack templates, identifying any differences.
Exam Tips: Answering Questions on Drift Detection
Understand the importance and functionalities of Drift Detection. You might need to identify its benefits or possible outcomes of not using it. Examiners might ask questions relating to the process of detecting drifts or how to handle detected drifts. Familiarize yourself with CloudFormation concepts and AWS management console as relevant questions might surface.
Your results would be enriched by practicing with resources provided by AWS and other platforms providing AWS training and preparatory questions for the examination.
