Infrastructure drift detection and remediation are crucial components of maintaining alignment between actual infrastructure and its intended configuration, especially in the dynamic, post-deployment phase known as day 2 operations. Despite robust preventative measures like code reviews, automated testing, and policy as code, real-world operations often necessitate emergency changes that bypass these controls, leading to drift. Pulumi offers a comprehensive workflow for managing drift, involving a three-step process of detection, reconciliation, and remediation using commands like `pulumi refresh` and `pulumi up`. By automating drift detection, teams can transform infrastructure management from a reactive to a proactive process, improving security, reducing costs by catching orphaned resources, and enhancing operational efficiency. This approach not only aids in swiftly resolving incidents and maintaining compliance but also empowers teams to scale operations effectively without increasing headcount, thus providing a competitive advantage in managing complex infrastructure environments.
