Why Snap CD: Modular Deployments

Short summary

Snap CD organizes modular Terraform deployments in a three-level hierarchy (stacks, namespaces, modules) with declarative dependency wiring that replaces terraform_remote_state and wrapper scripts. Each module is fully independent with its own state, credentials, and runner, while inputs flow from module outputs, literals, or encrypted secrets. Configuration is version-controlled Terraform code enabling reproducible, scalable infrastructure management.

• •Three-level hierarchy: stacks (environment/product), namespaces (team/layer), modules (independent Terraform roots)
• •Declarative dependency graph wiring with automatic apply ordering replaces fragile terraform_remote_state patterns
• •Fully version-controlled, reproducible infrastructure with runtime credential isolation and hierarchical permission inheritance
