Is there, in OCI, an equivalent of Orchestrations in Oracle Cloud Infrastructure Classic?

Content

Hi,

in OCI-C there are Orchestrations that enable definition of multiple infrastructure resources (instances, volumes, ssh keys..) in single JSON file (template), orchestrations can be deployed (that create all resources in bulk), monitored for state and have lifecycle actions (e.g. delete orchestration to delete all created resources).

Is there an equivalent in OCI API (not classic)? I wasn't able to find one.

Or is there any built-in tool to perform such automation of deployment of multiple infra resources? I'm aware of external tools (e.g. terraform) but I'm interested of internal such service, if any.

Thanks,
