Question

In an immutable infrastructure pattern, what is the primary mechanism used to eliminate configuration drift during a service update?

Accepted Answer

The primary mechanism used to eliminate configuration drift in an immutable infrastructure pattern is the complete replacement of existing server instances with new, pre-configured images. Configuration drift occurs when individual servers are modified over time through manual patches, software updates, or altered settings, causing them to deviate from their original intended state. In an immutable approach, servers are never modified after they are deployed. Instead, when an update or a change is required, the organization builds a new machine image, which is a snapshot containing the operating system, libraries, and application code in a finalized state. The system then provisions new instances using this updated image and terminates the old instances. Because the old servers are destroyed rather than updated, there is no opportunity for manual changes to persist or accumulate, ensuring every server remains identical to its original definition.
