1) Multi-cloud IaC governance is the main objective
When a single platform must manage AWS, Azure, and GCP with consistent policies and workflows, a multi-cloud Terraform platform (HCP Terraform, Spacelift, env0) may be more appropriate.
2) Need for predictable, license-style pricing
Infrastructure Manager costs are tied to Cloud Build execution and storage. Organizations requiring fixed per-seat or fixed monthly budgeting may prefer SaaS IaC platforms with clearer license models.
3) Requirement for advanced workflow orchestration
When rich approval chains, PR-driven deploys, environment promotion patterns, and deep policy-as-code across stacks are required, dedicated IaC platforms may offer more comprehensive capabilities.
4) Sensitivity to console UX and performance
If heavy console usage by many developers and responsive UI performance are critical acceptance criteria, note that some reviews report UI and performance issues.
