Implement Immutable Infrastructure Practices

This standard mandates the implementation of immutable infrastructure practices to reduce configuration drift and improve security by treating infrastructure as disposable.

1. Implement Immutable Infrastructure Practices:

Reduce configuration drift and improve security by treating infrastructure as disposable. This approach ensures consistent and secure infrastructure deployments.

• 1.1 Avoid Manual Changes:
  • 1.1.1 Rebuild Instead of Modify:
    • Avoid manual changes to deployed infrastructure—rebuild instead of modifying in-place.
    • Automate the prevention of manual infrastructure changes.
  • 1.1.2 Change Management:
    • Automate the tracking of infrastructure changes.
    • Implement change management tutorials.
• 1.2 Immutable Server Patterns:
  • 1.2.1 Golden Images and Containers:
    • Use immutable server patterns (e.g., golden images, containerised workloads).
    • Automate the generation of golden images.
  • 1.2.2 Pattern Implementation:
    • Automate the implementation of containerised workloads.
    • Implement pattern feedback collection.
• 1.3 Automated Tear-Down and Redeployment:
  • 1.3.1 Infrastructure Automation:
    • Automate infrastructure tear-down and redeployment processes.
    • Automate the execution of tear-down processes.
  • 1.3.2 Redeployment Management:
    • Automate the tracking of redeployment progress.
    • Implement redeployment tutorials.

By implementing immutable infrastructure practices, organisations can ensure consistent and secure infrastructure.
