The OTC Extensions contain an abstraction interface layer. Clouds can do many things, but there are probably only about ten of them that most people care frequently.
If you want to do complicated things, the per-service oriented portions of the SDK are for you. However, if what you want is to be able to write an application that talks to clouds no matter what crazy choices the deployer has made in an attempt to be more hipster than their self-entitled narcissist peers, then the Cloud Abstraction layer is for you.
The OTC Extensions provide an extension to the OpenStack SDK. Refer to its documentation for the details: <https://docs.openstack.org/openstacksdk/latest/>.
