Mutable vs. Immutable Infrastructure

Question

What is Mutable vs. Immutable Infrastructure?

Answer 1

Mutable infrastructure can be updated, configured as per the requirement. It is possible to login to servers, apply patches, update configuration, scale up/down it etc.

Immutable infrastructure is something which can never be modified once it is deployed. If a change is required, it would need a new deployment, add new infra and decommission the old one
