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:
- No In-Place Changes
Infrastructure gets replaced, not modified.
- Declarative Infrastructure
Desired state defined as code.
- Version Control
Infrastructure changes tracked in Git.
- Reproducibility
Environments become deterministic.
