# Orchestration

> Template-based infrastructure orchestration for Polystack Cloud Platform. Define, deploy, and manage cloud resources as code using declarative orchestration.

Define and deploy cloud infrastructure as code using declarative templates.
Polystack Orchestration enables repeatable, version-controlled provisioning of entire
application stacks — compute, networking, storage, and scaling policies — from a
single template file.
