immutable infrastructure

This article contrasts immutable and mutable infrastructure strategies in system administration, highlighting their use in Linux Bash scripting. Immutable infrastructure, using tools like Docker and Kubernetes, focuses on replacing elements rather than updating them. Mutable infrastructure, using tools such as Puppet and Bash itself, allows for continuous updates. The article discusses how Bash scripting supports both approaches, from setup in immutable environments to maintenance in mutable ones, ultimately helping organizations align their operations with their goals.
