OOM(ONAP Operations Manager) needs to support configurable deployment options of ONAP, to allow operators to choose and configure the deployment layout and choose technologies used for running ONAP. TOSCA allows modeling ONAP services, all of their components, and to model needed infrastructure components, such as Kuberetenes and OpenStack, and then to match the services with the desired infrastructure to run the ONAP services.
(ONAP Service Modeling Example With Kuberentes and OpenStack)
WHAT IS TOSCA
Topology and Orchestration Specification for Cloud Applications (TOSCA), is an OASIS standard language to describe a topology of cloud based web services, their components, relationships, and the processes that manage them. The TOSCA standard includes specifications to describe processes that create or modify services. TOSCA allows using a descriptive DSL to drive orchestration base the application declarative model.
WHAT IS Cloudfiy
Cloudify is an open source cloud orchestration framework. Cloudify enables modeling applications and services using a TOSCA based DSL, and automates the applications' entire life cycle, including deployment on any cloud or data center environment, monitoring all aspects of a deployed application, detecting issues and failure, manually or automatically remediating such issues, and performing ongoing maintenance tasks.
WHAT IS Kubernetes
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It supports a range of container tools, including Docker.
ONAP Architecture with Kuberentes and OpenStack
ONAP Relase 1 is deployed in Kubrentes PODs, that are run on OpenStack VM.

In the context of ONAP Operations Manager(OOM), we leverage TOSCA to describe and orchestrate all ONAP services, with all of their components.
How To (Deploy ONAP on Kubernetes using Clouidfy )
Cloudify creates VMs on OpenStack (TOSCA blueprint).
Cloudify utilizes two TOSCA blueprints, the first creates the cloud resources and deploy K8s and the second is a TOSCA blueprint deployes the ONAP services (see figure below)
