Immutable Infrastructure

Immutable infrastructure is a concept in software and IT infrastructure management where servers and components are never modified after they are created. Instead of making changes to existing systems, new versions are deployed to replace the old ones. This approach reduces errors and inconsistencies, as each instance is identical and built from the same template. It enhances stability, simplifies scaling, and makes it easier to roll back to previous versions if needed. Think of it like building with LEGO: instead of altering a structure, you build a new one from the same blocks, ensuring everything stays consistent and reliable.
