About Immutable Infrastructure

Immutable Infrastructure uses an immutable operating system to provision Kubernetes clusters. Unlike traditional OS-based clusters, all node configurations are baked into images and remain unchanged after deployment. Cluster upgrades and configuration changes are applied by replacing nodes with new images, ensuring consistency, reliability, and simplified operations throughout the cluster lifecycle.

supports Immutable Infrastructure through pluggable infrastructure providers, each versioned independently from the platform. See Infrastructure Providers for the full provider list and what each provider supports.

Note
Because Immutable Infrastructure releases on a different cadence from Alauda Container Platform, the Immutable Infrastructure documentation is now available as a separate documentation set at Immutable Infrastructure.
