SDNZone: CohesiveFT – SDN, NFV Can Enable CSP Differentiation with VPCs

Software-defined networking and network functions virtualization can help cloud service providers (CSPs) survive and thrive in an increasingly competitive marketplace.

CSPs can leverage SDN and NFV to differentiate by delivering Virtual Private Clouds (VPCs), says Ryan Koop, director of products and marketing at CohesiveFT, which provides a range of products and services to help enterprises use virtual and cloud computing. VPCs enable subscribers to secure their data within public clouds and connect back to resources in the enterprise CSPs, Koop wrote in a recent CloudTweaks piece, adding that they can ease the transition into the cloud and add value for customers.

Here are the two paths for getting there, according to Koop.

The first is to establish and expose an SDN layer. That can be exposed to customers via an API.

The second, potentially more affordable, approach entails implementing the VPC in software by leveraging NFV technology. All you need to do in this scenario is to offer an image to customers as part of a standard image library, Koop says.  In this case, the customer controls the software – and thus has full control in terms of address, protocols, security and topology, and the solution runs on existing virtual machines within the network that’s already deployed.

As discussed in a recent SDNzone SDNZone posting, Chicago-based CohesiveFT rolled out its core software defined networking product, VNS3, in Google Compute Engine this past August. It is designed for enterprises using, or looking to use, GCE to create a VNS3 overlay network to control addressing, protocols, topology and encrypted communications in the cloud. VNS3 offers the benefits of six devices in one: a virtual firewall, router, switch, protocol re-distributor, IPsec concentrator and a scriptable REST API.

“Google Compute Engine is the one to watch as they have the potential to challenge AWS on both feature set and price point,” said CTO Chris Swan. “As the GCE community grows, we hope to be a key hybrid and federated network component in all GCE customer deployments. VNS3 simplifies the path for customers to try GCE and connect their on-premises networks across existing public cloud topologies and to new GCE deployments.”
