OOM(ONAP Operations Manager) needs to support configurable deployment options of ONAP, 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.

Cloudify is an open source cloud orchestration framework. Cloudify is a model-driven orchestrator, it 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.

WHAT IS Model-driven Orchestration

Model driven orchestration allows modeling of services and applications using a declarative and descriptive language, then to operate the application using the model. This includes deployment of the application, healing failures, scaling and others. Instead of executing manually crafted workflows, the orchestrator creates dynamic execution workflow graph, based on the application model. Each node of the graph triggers a corresponding lifecycle operation execution, while the orchestrator keeps track and stores state in a context object allowing passing information from one operation to another.

WHAT IS Kubernetes

...

• Define reusable TOSCA node types. Each type can declare the interfaces for its lifecycle operations.
• Create a TOSCA template YAML. The template describes the components, services and all of their dependencies and relationships. 
• Cloudify Orchestrator creates a deployment graph, at run time. Executing the Install workflow traverses thru the graph, and executes relevant lifecycle operation interfaces.
