In the world of infrastructure management, two fundamental approaches govern how resources are deployed and maintained: mutable and immutable infrastructure. These approaches influence how updates are made, how infrastructure evolves, and how consistency is ensured across different environments.

Mutable infrastructure refers to systems that can be changed or updated after they’ve been initially deployed. This means that configuration changes, software updates, or patches can be applied directly to existing infrastructure resources without replacing them entirely.  For instance, a server can be updated by installing new software, tweaking its settings, or increasing its resources. While the server itself stays the same, its configuration evolves over time.
