-
-[Nuage](https://www.nuagenetworks.net) provides a highly scalable policy-based Software-Defined Networking (SDN) platform. Nuage uses the open source Open vSwitch for the data plane along with a feature rich SDN Controller built on open standards.
-
-The Nuage platform uses overlays to provide seamless policy-based networking between Kubernetes Pods and non-Kubernetes environments (VMs and bare metal servers). Nuage's policy abstraction model is designed with applications in mind and makes it easy to declare fine-grained policies for applications.The platform's real-time analytics engine enables visibility and security monitoring for Kubernetes applications.

-Kubernetes supports multiple virtual clusters backed by the same physical cluster.
-These virtual clusters are called namespaces.
+In Kubernetes, _namespaces_ provides a mechanism for isolating groups of resources within a single cluster. Names of resources need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects _(e.g. Deployments, Services, etc)_ and not for cluster-wide objects _(e.g. StorageClass, Nodes, PersistentVolumes, etc)_.

+### Workload resources for managing pods
+
 Usually you don't need to create Pods directly, even singleton Pods. Instead, create them using workload resources such as {{< glossary_tooltip text="Deployment"
 term_id="deployment" >}} or {{< glossary_tooltip text="Job" term_id="job" >}}.
 If your Pods need to track state, consider the
