Immutable Infrastructure: The concept of replacing existing infrastructure components or systems instead of updating them. With an immutable infrastructure, once a system or component is deployed, it is not modified – any changes lead to a new deployment of a system or component. This philosophy is intended to increase the reliability, consistency, and repeatability of infrastructure, helping to mitigate risks associated with changes and providing a high level of auditability.
