Best Practices1

Immutable Infrastructure

An operations model where servers and components are never modified after deployment; changes ship as freshly built, versioned replacements rather than in-place edits.

Anti-Patterns2

Anti-Pattern

Snowflake Server

A server hand-configured over time into a unique, irreproducible state that no one can recreate, document, or safely replace.

Anti-Pattern

Pets vs Cattle (Pet Servers)

Treating individual servers as irreplaceable pets that are named, nurtured, and manually healed, instead of disposable cattle that are replaced on failure.

Blueprints1

Blueprint

Snowflake Servers to Immutable Infrastructure Blueprint

Replace hand-tuned snowflake servers with immutable infrastructure built from versioned images and replaced, never patched, in place.
