This document discusses TOSCA (Topology and Orchestration Specification for Cloud Applications), an open standard for automating the deployment and management of cloud applications and services. It introduces ARIA, an open source TOSCA orchestration engine library that implements the TOSCA orchestration workflow. ARIA provides a common language and abstraction layer for orchestrating cloud resources across different platforms using declarative YAML definitions and reusable node types.
