Explain advanced immutable infrastructure and GitOps deployment architecture in PHP systems.

Updated May 24, 2026

Short answer

Immutable infrastructure and GitOps replace mutable server management with declarative, version-controlled, reproducible deployment systems.

Deep explanation

Traditional infrastructure relied on manually changing live servers.

Problems included:

  • configuration drift
  • inconsistent environments
  • difficult rollbacks
  • undocumented changes
  • fragile deployments

Immutable infrastructure solves this by treating servers as disposable artifacts.

Core principles:

  1. No In-Place Changes

Infrastructure gets replaced, not modified.

  1. Declarative Infrastructure

Desired state defined as code.

  1. Version Control

Infrastructure changes tracked in Git.

  1. Reproducibility

Environments become deterministic.
