Global Credit Card Payments
Company Modernizes WAN
Infrastructure with Versa SD-WAN
A global company providing payment services, and financial andcommerce technology solutions, needed to transform its WAN
infrastructure to better support its customers. Their customers
include financial institutions and merchants, corporations andconsumers. To support their integrated solutions, the company
required a new software-based infrastructure that would movemoney and information at scale, and accelerate services at therapidly increasing pace of change.
The company required a comprehensive modernization of their WAN, andone that would enable them to stand apart as a global leader of Fintech,
payments and commerce, and create differentiated value for their customers.

The Problem

RESULTS• Complete WAN modernization• Cloud-ready network supports all
sites and services

constrained by physical infrastructure. To overcome this, they needed asoftware-based, virtual solution, that would fully leverage the cloud – aapplications and workloads to scale on-demand.

The company was struggling with network complexity that held them backfrom much needed innovations. Hardware device sprawl had become too
costly and cumbersome. A solution was needed to simplify their networking
and computing environments. They also wanted to work with technology
partners that would use best practices to help them with installation,

Simplified

deployment and support.

Automatedand workloads were continuously changing, with a myriad IoT devices andsensors, and a vast array of IaaS, private, public, hybrid and multi-clouds.
The company had multiple needs and use cases identified for their SD-WAN
deployment, including:• Operational management

The Solution – Versa Networks SD-WAN
To accomplish their WAN transformation, the company chose Versa Network’s SD-WAN. Versa’s single platform, withmulti-function VNFs, provided the diversity of features and flexible deployment capabilities the company needed. Versa
enabled them to simplify their network infrastructure, reduce their multi-site footprint – everywhere, and lower thecost of deployment and operational management. Versa SD-WAN software is installed on vendor agnostic hardware atbranch locations that deploy services that scale based on the size of each location.
Deploying virtual network services within a software-defined infrastructure allowed the company to centralize allfunctions into a set of compute blocks that easily scale by simply adding compute nodes, rather than deploying
more hardware.
The company’s network product development is now built on ETSI standards to support network function virtualization(NFV), which allows the company to virtualize functions like routing, firewalling, network optimizations and others,
running them on a hypervisor. This approach provides a holistic framework for the company build out of their network
infrastructure, and the products and services that run on the network. They also leverage service chaining, to pass
information among the virtualized network functions, all running within universal CPEs located in their distributed sites
and cloud services.
Key SD-WAN functional requirements include:• Rapid onboarding through a programmable, self-service model• Deploying diverse sites with consistency, driven by automation• Consistent REST API for all programming and reporting• Reducing complexity with a controller-based routing typology using an overlay• CMDB with all relevant IT hardware and software information, and their relationships• Integration with their legacy network• Software-based and hardware independent• Layer 7 application-aware
The company deploys their NFV and Versa virtual network function (VNF) infrastructure on top of VXSI. The Versa
SD-WAN is a substantial part of the network solution. Versa’s software-only SD-WAN has allowed them to deploy it
wherever they need. Whether at public cloud sites, edge transit nodes, branch locations and data centers, all use thesame API model, with consistent features, functions and configurations.
The company’s centralized orchestration, management and analytics are critical to the entire network for monitoring
and controlling the services and underlying computing infrastructure. This allows them to automate various functions fora particular location, stringing the automated functions together, and also stringing them across the network computeinfrastructure, to simplify provisioning and ensure efficient and appropriate resource allocation.
Automation and virtualization provide more consistent and reliable infrastructure services. Central orchestration
enables end-to-end servicing, using multiple automated actions to give users access to data center services. For
example, building a VPN tunnel, configuring a VIP, changing a firewall, setting up route peering – and verifying aservice is operational.
The company has public, private, hybrid and multi-cloud environments that support office users, mobile users, and IoT
devices that are distributed around the world. Their data centers are all layer 2-3 switching and routing, while all other edge
services are virtualized, using the same VNFs deployed at all their sites, for reliability, consistency and business continuity.

Edge transit nodes at communication service provider (CSP) locations provide the company with high bandwidthconnectivity to multi-cloud and SaaS providers within a single location. Connecting to customer networks at the same
colocation site allows the company to fully leverage the edge transit nodes.

The Results
By deploying virtual infrastructure, they are now free from the constraints and limitations of physical infrastructure. By
eliminating the plethora of single-function hardware devices, the company has reduced Capex, power consumption, andmaintenance and support costs. By adopting a software-based approach, they moved away from the end of life, and endof support challenges, associated with the traditional hardware refresh model.
Now, rather than over-subscribing routers, firewalls, etc., they dedicate the appropriate amount of CPU and memory foreach virtual function, based on best practices. In doing so, they save money, because they run their virtual infrastructure
on lower cost commodity CPE devices.
By moving away from the costly proprietary hardware pricing model to a software and cloud-based model, the company
is able to have flexible licensing based on a subscription. This has also solved the problems associated with ripping
and replacing physical equipment, and the frustration with the long timeframes to get new features and functions withhardware equipment.
