Daily Term: Immutable Infrastructure

Immutable Infrastructure

Immutable Infrastructure is a paradigm where infrastructure components, like servers, are never modified after deployment—instead, they’re replaced with new instances when changes are needed. For example, if a web server needs an update, a new server image with the update is created and deployed, replacing the old one. This approach ensures consistency and simplifies rollbacks, but it requires automation tools and can increase deployment frequency.
