Software-defined wide area networking (SD-WAN) is being embraced steadily by enterprises of all kinds globally.

According to IDC, SD-WAN revenues are estimated to exceed $5.25 billion in 2023. One key challenge observed is the interoperability of multiple SD-WAN solutions within an environment, possibly resulted from mergers and acquisitions or new demands in the network.

Global organisations are approaching SD-WAN in a way that allows them to scale for future needs.

The interoperability challenge of integrating different vendors’ systems has resulted in the Metro Ethernet Forum (MEF) 3.0 gateway that facilitates the use of standardised Lifestyle Services Orchestration (LSO) APIs to fix the issue cleanly.

This standard defines, delivers, and certifies agile, assured and orchestrated services across a global ecosystem of automated networks. It is a critical framework that enables the orchestration of networking across multiple service providers.

On the other hand, there is a growing number of born-in-the-cloud companies that have never own any physical IT assets or network infrastructure. This creates new problems as they expand geographically and connect disparate locations to the cloud. To reap the full benefit of cloud-based applications, enterprises should consider accessing the cloud via a managed SD-WAN.

Orchestrating cloud benefits with SD-WAN

The on-demand connectivity of software-defined networking (SDN) is the foundation for connecting the cloud and offering partners a seamless approach to growing their business and reaching new markets.

Organisations—especially retail, international banking and financial services—can turn up new services and manage network performance at the click-of-a-button, giving them the agility, flexibility, scalability and simplicity needed to serve today’s enterprise demands.

SD-WAN expands this environment down to the enterprise WAN that connects corporate users anywhere around the world. 
As an overlay technology, SD-WAN gives the enterprise control over the way they orchestrate WAN connectivity whether it’s configuring network policy between branches or access to public clouds. When deployed over a carrier-grade backbone network, enterprises can enjoy reliable and secure connectivity across the entire WAN.
Cost-effective branch connectivity
Providing fast, efficient service between every branch office and the nervous system of a financial services business requires best-in-class network connections throughout the WAN and cloud.
Yet, all that security and efficiency normally comes at a cost via traditional MPLS networking. But customers always want better service without extra fees and OPEX costs!
This is where an SD-WAN infrastructure can offer all the frills without the bills.
Virtualising the network with SD-WAN offers higher performance, greater efficiency and security benefits while lowering overall costs. Traffic flow can be prioritised so that mission-critical application data jumps to the head of the line.
While this technology is profitable for nearly all businesses, banks and retail financial sectors would find this particularly relevant with every move to transform and to migrate to the cloud.
SD-WAN increases immensely the amount of bandwidth that bank branches have, at a fraction of the price of traditional private circuit lines like MPLS. Edge devices can be installed in minutes without the physical presence of IT personnel. The limits to the number of data centres that a branch is connected to are also removed.
This immediately eliminates the issue that traditional bank communication networks have of needing to backhaul cloud application traffic back to the headquarter, resulting in reduced costs, latency and inefficiencies.
Secure efficiency from branch to branch
Financial institutions have additional security and compliance responsibilities over other types of businesses, and this is where SD-WAN excels.
As banks and credit unions rocket into the future with advances such as video, mobile banking and digital signage, reliable connectivity has to be the critical puzzle piece in maintaining a great user experience.
SD-WAN can be that key to unlocking reliability and offer a foundation for digital transformation.
Furthermore, the combination of on-demand connectivity and SD-WAN means being able to take advantage of interconnection services with direct connectivity to multiple cloud service providers and data centres globally.
This reaps additional cost and business-risk benefits that add up to substantial efficiencies in scalability, security and seamless management of multi-cloud deployment.
When partnered with a carrier-grade connectivity specialist with a global reach, financial and other large corporations can leverage SDN and SD-WAN to manage their enterprise connectivity and establish direct cloud connections globally with greater performance, security and reliability.
It is a unique global network fabric that harnesses more digitalisation benefits than any traditional WAN model.
Now that is connectivity enterprises can bank on.
