What is HashiCorp Terraform?

Terraform is an open‑source IaC tool that lets you define cloud, on‑prem, and SaaS resources in declarative configuration files. It builds a dependency graph, creates an execution plan, and applies changes safely across multiple providers. With a single workflow you can version, share, and reuse infrastructure definitions, enabling consistent environments from development to production while reducing manual errors.

Spacelift

AI-suggested

Spacelift is an infrastructure-as-code orchestration platform that runs GitOps-style pipelines for Terraform, OpenTofu, CloudFormation, Pulumi, and Kubernetes. It's built for platform and DevOps teams that need to give developers self-service infrastructure provisioning while keeping governance and audit trails intact. The platform includes native state understanding and drift detection, policy-as-code enforcement using Open Policy Agent, and self-service 'Blueprints' that let developers provision infrastructure through golden paths without manual approvals. Spacelift also offers an AI assistant for natural-language infrastructure requests, multi-tenant Spaces for team-scoped access, and deployment options including SaaS, self-hosted, on-premises, and FedRAMP-authorized environments.
