This paper introduces "Ephemeral DevOps," a novel approach to infrastructure and pipeline management based on the principle of planned self-destruction and continuous recreation. By embracing impermanence, this ChaosSecOps-driven methodology forces extreme automation, enhances resilience, proactively mitigates security vulnerabilities, and fosters a culture of continuous improvement. This paper presents a comprehensive guide to implementing Ephemeral DevOps, including architectural diagrams, practical code examples (Terraform, AWS Lambda, Jenkins), and a detailed real-world case study demonstrating its application in a highly available, secure e-commerce platform on AWS. This paradigm shift offers significant advantages over traditional, long-lived infrastructure, enabling faster deployments, improved security posture, and greater agility in the face of evolving threats.
