What have you done to ensure consistency across unit quality and production environments?

To ensure consistency across unit quality and production environments, I have implemented infrastructure as code (IaC) practices using tools like Terraform and Docker, which facilitate reproducible environments. Additionally, I utilize continuous integration/continuous deployment (CI/CD) pipelines to automate testing and deployment processes, ensuring that code behaves the same way in both environments. Regular monitoring and logging are employed to quickly identify and resolve any discrepancies that may arise. Finally, I maintain comprehensive documentation and version control to track changes and configurations consistently.
