Virtualized Cloud Services

Make cloud services and datacenter networks more agile with policy-based automation


Virtualized Cloud Services (VCS) is the datacenter and cloud networking framework of Nuage Networks Virtualized Services Platform (VSP). It lets you automate the configuration, management and optimization of virtual networks, including security services that provide tenant isolation and access controls to individual applications and workloads.

Designed for service providers and enterprises, VCS is a non-disruptive software-defined networking (SDN) overlay for all virtualized and non-virtualized server and network resources. It is transparent to the underlying physical infrastructure and provides a complete cloud networking framework that requires no specialized hardware. You can install all components of VCS in Docker containers, hypervisors or virtual machines.

With VCS, you can use policy-based automation to make your IT services more responsive and increase your business agility. VCS helps you eliminate the constraints and complexity of cloud networking so that you can:

  • Make your network as dynamic and flexible as compute resources by automating instantiation of network services and devices
  • Gain a competitive advantage by supporting open-source and emerging tools such as Docker containers
  • Scale to meet the demands of thousands of tenants that have unique application requirements, distinct security policies and committed service levels
  • Apply granular security policies in an intelligent, consistent and provable way across the entire cloud

Open platform capabilities

VCS provides robust interfaces that let you manage existing legacy infrastructure together with leading-edge software and hardware, such as Docker containers and network accelerators. You can integrate the platform with a broad range of tools and environments – from cloud platforms such as CloudStack and OpenStack to custom self-service interfaces.

VCS unifies cloud policies across all types of workloads, virtualization platforms and cloud providers

Cloud consumption interface controls can unify, or federate, any combination of public and private clouds into a single, coherent cloud that can be:

  • Orchestrated by cloud platforms such as CloudStack, OpenStack, Microsoft System Center and VMware vCenter
  • Provisioned by customers and administrators through open interfaces such as OpenStack Horizon
  • Customized through a wide range of development environments, including Docker containers, with Kubernetes and Mesos

A flexible network interface provides:

  • Control of virtualized and bare-metal resources (such as network equipment from Nokia, Arista and HPE) without requiring upgrades
  • Multiple server virtualization environments side by side, including Linux KVM, Microsoft Hyper-V, VMware and Docker containers

Extensibility and security interface features enable:

  • Integration with applications such as Oracle, third-party anything-as-a-service approaches, security appliances and operating systems such as Red Hat and Ubuntu Linux
  • Controllable network resources through policies and templates that are preset by the network team or defined using an intuitive user interface
  • Customization

An operational scalability interface delivers:

  • Efficient, multitenant operations at cloud scale with features such as multicast and network template capabilities
  • Robust overlay/underlay visibility through our Virtualized Services Assurance Platform

Key elements of Nuage Networks VCS

Consistent with SDN tenets, VCS includes a cloud service management plane, a datacenter control plane, and a datacenter data plane. It is made up of three key software-based components:


Virtualized Services Controller

VSC provides a robust control plane for the datacenter network, maintaining a full per-tenant view of network and service topologies. Through network APIs that use interfaces such as OpenFlow, VSC programs the datacenter network independent of datacenter networking hardware.

Virtualized Services Directory

VSD is a policy, business logic and analytics engine that supports the abstract definition of network services. Through RESTful APIs to VSD, administrators can define and refine service designs and incorporate enterprise policies.

Virtual Routing and Switching

The VRS module serves as a virtual endpoint for network services. It detects changes in the compute environment as they occur and instantaneously triggers policy-based responses to ensure that the network connectivity needs of applications are met.

Nuage Networks 7850 Virtualized Services Gateway

Bridging the virtualization gap
Many real-world datacenters mix of virtualized and non-virtualized assets. A new breed of gateway is needed to help all datacenters benefit from automation and network virtualization.

7850 VSG seamlessly extends SDN 2.0 functionality between virtualized and non-virtualized assets in the datacenter. This high-performance gateway provides highly scalable (up to a terabit of capacity in a single rack unit), multi-tenant gateway functionality at Layers 2 to 4.

7850 VSG supports a fully automated network infrastructure by working with the Nuage Networks VSP to automatically extend application policies across virtualized and non-virtualized assets. It complements our existing VRS-G software gateway and supports VXLAN Tunnel Endpoint (VTEP) “white box” devices from our partners.

Key Elements of the 7850 VSG


  • Ultra-high-density 10 and 40 Gigabit Ethernet (GE) switch providing VTEP gateway, IP routing and top-of-rack functionality for virtualized and non-virtualized datacenter environments

  • Industry-leading 10GE density of 96 ports in a compact 1RU form factor, saving valuable datacenter rack space

  • Highly efficient power and cooling, with redundant power supplies and options for back-to-front and front-to-back airflow.

  • Provides SDN-enabled virtualization with support of Layer 2 to Layer 4 services

  • Provides SDN-enabled virtualization with support of Layer 2 to Layer 4 services

  • Provides SDN-enabled virtualization with support of Layer 2 to Layer 4 services
