Spacelift for Infrastructure Automation

Overview

Spacelift is an infrastructure orchestration platform for Terraform and other IaC workflows with policy controls and approvals.

Why Teams Use Spacelift

• Centralized run management
• Policy-as-code gates
• Drift detection
• Environment and stack dependency control

Practical Example

A stack triggers on pull request changes, runs plan, evaluates policy checks, and requires approval before apply.

Production Example

Platform teams commonly use Spacelift to enforce tagging, cost constraints, and security controls across dozens of Terraform stacks.

Common Pitfalls

• Weak policy coverage for high-risk changes
• Unclear stack ownership metadata
• Ignoring drift alerts

Key Takeaways

• Spacelift improves governance for IaC at scale.
• Policy gates and approvals reduce change risk.
• Drift monitoring is important for long-term consistency.
