Such an approach will give you an immutable infrastructure that allows for little or no configuration drift. In large and complex environments where full replacement of infrastructure is not always feasible, changes can be made at the component level. Using automated scripts will ensure changes are implemented with consistency.

Immutable infrastructure (ii) provides stability, efficiency, and fidelity to your applications through automation and the use of successful patterns from programming. No rigorous or standardized definition of immutable infrastructure exists yet, but the basic idea is that you create and operate your infrastructure using the programming concept.
Immutable infrastructure takes a different approach – where servers once deployed cannot be modified. The configuration is applied at server boot time – that is the way to deploy the same image into multiple environments.
An immutable infrastructure is an approach to managing services and software deployments on it resources wherein components are replaced, rather than changed. An application or service is effectively redeployed each time any change occurs.
Put simply, immutable infrastructure is a model in which no updates, security patches, or configuration changes happen “in-place” on production systems. If any change is needed, a new version of the architecture is built and deployed into production.

Immutable infrastructure is built out of service components that are similar to code objects—service components intended to perform a limited function. As with a code object, when you change an infrastructure object, it gets replaced with a new version.
An immutable infrastructure is another infrastructure paradigm in which servers are never modified after they’re deployed. If something needs to be updated, fixed, or modified in any way, new servers built from a common image with the appropriate changes are provisioned to replace the old ones.

It is a paradigm for infrastructure deployment and maintenance in which servers are never modified after they are deployed. In order to make any update or fix the software, new servers built from the base image with the modifications are deployed and the old servers are deprovisioned.
