Question

How do you mitigate configuration drift in your IaC setup?

This question is dedicated to the understanding of most common problems with database migrations in CI/CD pipelines and their solutions. Actually, database migrations are much more sensitive to data inconsistency, loss, or system downtime if there are plenty of environments or large data volumes. The following must be mentioned in the answer schema conflicts, backward compatibility issues, dependency management, and production systems downtime. This will provide effective solutions such as version-controlled migration tools-flyway, liquibase, rollback, database snapshots, and automated testing that ensure efficient integration with minimal disruptions across different deployment stages.

Answer 1

Configuration drift can be defined as when infrastructure configurations diverge from IaC templates that are agreed on. Ways to limit drift include:

Frequent Re-Applications: Regularly run IaC templates using commands like terraform apply to ensure your infrastructure remains consistent with the agreed-upon configuration state.

Automated Drift Detection: Use tools like Terraform drift detection and AWS Config to monitor infrastructure state and then alert when infrastructure state doesn't match the expected state.

Scheduled Audits: Schedule regular audits that check the actual infrastructure against the IaC definitions to catch any drift and fix it right away.

CI/CD Integration: Infrastructure deployments can be automated using CI/CD pipelines, which reduce the risk of drift from a manual change in configuration.
