Atmos Features
Atmos brings infrastructure, applications, and operational tools into one stack-based configuration system. Manage Terraform and OpenTofu, Kubernetes, Helm, containers, and more with shared configuration, authentication, and automation.
Designed to be cloud agnostic, Atmos enables you to operate consistently across various cloud platforms. Expand a feature to see what it does and open its reference documentation. Features marked experimental in their reference pages follow the experimental feature settings.
