1. Introduction & Overview<\/strong><\/h1>\n\n\n\n

\ud83d\udd0d What are Rollbacks?<\/h3>\n\n\n\n

A rollback<\/strong> is the process of reverting a system, application, or service to a previous stable state following a failed or problematic deployment. In DevSecOps, rollbacks are automated safety mechanisms integrated into CI\/CD pipelines to ensure system reliability, security, and uptime.<\/p>\n\n\n\n

\ud83d\udd70 History or Background<\/h3>\n\n\n\n
    \n
  • Origin<\/strong>: Rollbacks were traditionally manual processes performed by sysadmins or DBAs.<\/li>\n\n\n\n
  • Evolution<\/strong>: With DevOps, and later DevSecOps<\/strong>, rollbacks evolved into automated, secure, and auditable workflows.<\/li>\n\n\n\n
  • Current Trend<\/strong>: Tools like Argo CD, Spinnaker, GitHub Actions, and Kubernetes operators support automated rollback capabilities.<\/li>\n<\/ul>\n\n\n\n

    \ud83d\udea8 Why Is It Relevant in DevSecOps?<\/h3>\n\n\n\n
      \n
    • Ensures security posture<\/strong> after failed patches.<\/li>\n\n\n\n
    • Helps maintain compliance<\/strong> by avoiding unstable releases.<\/li>\n\n\n\n
    • Enables continuous deployment<\/strong> without compromising safety.<\/li>\n\n\n\n
    • Builds trust by enabling rapid recovery<\/strong> from faulty builds.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      2. Core Concepts & Terminology<\/strong><\/h2>\n\n\n\n

        3. Architecture & How It Works<\/strong><\/h2>\n\n\n\n

        • CI\/CD Tools<\/strong> (GitHub Actions, GitLab CI, Jenkins, Argo CD)<\/li>\n\n\n\n

          If image not possible:<\/p>\n\n\n\n
          \n
          The rollback architecture consists of CI\/CD pipelines that deploy artifacts using tools like Argo CD or Jenkins. Monitoring tools continuously check system health. On failure detection (e.g., 500 errors, security alert), the orchestrator triggers a rollback via Helm, Docker tags, or infrastructure snapshots (e.g., Terraform state or AMI).<\/p>\n<\/blockquote>\n\n\n\n
