What are common anti-patterns for Immutable infrastructure?

Immutable infrastructure is a powerful approach to managing deployment, but certain anti-patterns can undermine its benefits. Understanding these pitfalls is crucial for effectively implementing this model.

Common Anti-Patterns for Immutable Infrastructure

  • Mutable Changes: Making changes directly to running instances instead of creating new ones.
  • Inconsistency in Environments: Running different versions of applications or configurations across environments.
  • Failure to Version Control: Not using version control for infrastructure code can lead to difficulties in tracking changes.
  • Neglecting Rollback Plans: Failing to have clear strategies for rolling back deployments can lead to prolonged downtime.
  • Complex Dependency Management: Over-complicating dependencies can create challenges in the deployment process.
  • Not Automating Provisioning: Manual provisioning of resources can introduce human error and inconsistency.

Example

// Example of creating a new immutable instance instead of changing the existing one function deployNewInstance($appVersion) { $instance = new Instance(); $instance->setAppVersion($appVersion); $instance->create(); echo "Deployed new instance with version: " . $appVersion; }
