TheSDN overlaymodel provisions tunnels between the virtual endpoints within and across data centers2.This model uses network overlays to support private communication between instances3. Reference from Juniper site:Microsoft Learn,Red Hat Customer Portal

OpenShift includes a preconfigured, preinstalled, and self-updating monitoring stack that provides monitoring for core platform components4.You also have the option to enable monitoring for user-defined projects4. This means OpenShift has its own monitoring framework (B) and is able to configure customized alerts (D). Reference from Juniper site:OpenShift Container Platform

In a cloud-native microservices-based architecture, the various modules of an application communicate throughapplication programming interface (API) calls5.Each service is autonomous and self-contained and runs a unique process6. Reference from Juniper site:Microsoft Learn,Palo Alto Networks

In OpenStack networks, it is possible to share networks with other projects7.Also, it is possible to enable DHCP for a subnet in an OpenStack network7. Reference from Juniper site:OpenStack Documentation

OpenStack's networking service is known as Neutron. Neutron provides a scalable, API-driven, web services-based model for network connectivity as a service. It is designed to manage and configure networking services for both simple and complex network topologies. Neutron allows users to create their own networks, control traffic and connect servers and devices to one or multiple networks.

In a CN2 deployment using Kubernetes as the orchestrator, the vRouter agent is contained in the worker node. The vRouter agent is responsible for managing the forwarding plane on each node in a Contrail cluster. It interacts with the kernel to manage the services and interfaces within the virtual networks.

The configuration plane is the function that enables CN2 to manage its resources and interact with the kube-api. The configuration plane is responsible for storing and managing all configuration data in a Contrail cluster. It provides APIs for other components to retrieve this data. This allows CN2 to manage its resources and interact with the kube-api.

The vRouter agent microservice is the CN2 component responsible for generating associated routes. When a pod is scheduled on a node, the vRouter agent on that node programs the necessary routes in the kernel routing table to ensure that traffic destined for that pod is properly routed.

OS-level virtualization requires less duplication of hardware resources. This method allows multiple instances of an operating system or multiple different operating systems to run on a single physical server, sharing the same hardware resources. This results in more efficient use of hardware resources compared to other virtualization methods such as full virtualization or paravirtualization
