The Orchestration service provides a template-based orchestration engine for the OpenStack cloud, which can be used to create and manage cloud infrastructure resources such as storage, networking, instances, and applications as a repeatable running environment. Templates are used to create stacks, which are collections of resources. For example, a stack might include instances, floating IPs, volumes, security groups, or users. The Orchestration service offers access to all OpenStack core services via a single modular template, with additional orchestration capabilities such as auto-scaling and basic high availability. For information about the: Basic creation and deletion of Orchestration stacks, refer to the End User Guide. heat CLI commands, see the OpenStack Command Line Interface Reference As an administrator, you can also carry out stack functions on behalf of your users. For example, to resume, suspend, or delete a stack, run: $ action-resume stackID $ action-suspend stackID $ stack-delete stackID
