Terraform Enterprise Architecture

This page describes aspects of the architecture of Terraform Enterprise.

Note: This page was written for a prior implementation of Terraform Enterprise, and may be outdated. We plan to review our architecture documentation in the near future.

Services

These are the services used to run Terraform Enterprise. Each service contains a description of what actions it performs, a policy for restarts, impact of failing or degraded performance, and the service's dependencies.

atlas-frontend and atlas-worker
archivist, binstore, storagelocker, and logstream
terraform-build-manager, and terraform-build-worker
slug-extract, slug-ingress, slug-merge
