OOM(ONAP Operations Manager) needs to support configurable deployment options of ONAP and to allow operators to choose and configure the deployment layout and choose the technologies used to run ONAP. TOSCA allows creating the ONAP services models, and deploy ONAP using the TOSCA service models.
Cloudify follows the base TOSCA template, creates OpenStack VMs, deploys Kubernetes on them, and then deploys Kuberentes PODs with all ONAP services.
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 Cloudfy TOSCA Blueprint
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 )
Cloudity 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)
Cloudfiy Deploys Kuberenetes on OpenStack VMS (TOSCA blueprint)
Cloudfioy creates a POD (TOSCA blueprint)
Cloudify Deploys ONAP on POD (TOSCA blueprint)
OOM Cloudify Release 1 - Amsterdam
- Use TOSCA to provision OpenStack VMs
- Use TOSCA to deploy Kuberentes
- Use TOSCA to deploy ONAP services on Kubernetes
