The changing IT landscape.

Cloud and the consumerisation of IT is powering intelligent new ways of working, giving businesses the agility and flexibility to adapt to constantly changing markets. Enterprises are increasingly moving away from traditional data centre ownership and moving their IT infrastructure, applications and data to the cloud.

Foundations for a successful cloud-first strategy

To fully realise the benefits of the cloud, you need a robust connectivity foundation; one that is agile, flexible, cost effective and easy to manage. So, if these things aren’t always associated with MPLS, how should you connect your data and applications? Enter SD-WAN.

SD-WAN takes centre stage

For forward-thinking businesses, SD-WAN has become the next generation networking solution of choice. It provides an easy to manage, cloud optimised, ‘zero touch’ application aware network that can run over a variety of access technologies, including broadband and Internet, 4G and private circuits.

SD-WAN also provides the ability to load share, by dynamically routing traffic across any of your chosen access technologies. This enables unused bandwidth to be leveraged on backup connections, whereas in a traditional network set-up, it would sit idle and unused.

However, it’s key to remember that SD-WAN itself is not connectivity. The tendency is to compare SD-WAN vs private (MPLS), yet true comparisons should be made between SD-WAN vs VPN or private vs Internet. For example, SD-WAN will not help you fix poor connectivity. If your connectivity drops, it will be down to the carrier to resolve. SLAs and uptime are all governed by your connectivity provider. Not the SD-WAN vendor.

Remain cybersecurity-savvy

As with all networking solutions, a security plan is critical. Traditional networks are often made up of multiple internet connections and firewalls which make networks harder to manage, as the security profile is expanded, increasing the attack vector for potential hackers. SD-WAN alleviates this challenge with enhanced security, such as Next Generation Firewall (NGFW) and Advanced Threat Protection (ATP).

What about cost?


Popular in the US and countries with larger landmasses, SD-WAN was originally pitched as a way of reducing costs. However, in countries with smaller landmasses, like the UK, the difference between Internet and private (MPLS) connectivity is minimal. At the end of the day, all network providers purchase cables in the ground from the same group of suppliers and decide how to provision them – either as a private (MPLS) or public (Internet).

Due to these cost similarities, SD-WAN often results in overall cost increases due to additional investment required in on-site equipment and licensing.

However, not all SD-WANs are the same. Network providers that have their own software-defined network (SDN) infrastructure can provide a managed SD-WAN as part of a managed service, removing the need, and associated costs, of additional on-site equipment or license subscriptions.

So, should you be considering SD-WAN?

Quite simply – yes!

Always ahead of the curve, Bistech has been providing the features of SD-WAN before the term was even coined. We connect customers to our Private IP Backbone and SDN, delivering a Managed SD-WAN as our standard.

With Bistech, you get the flexibility of SD-WAN with the quality and reliability of MPLS, but without the cost, complexity and headache of managing the infrastructure and connectivity yourself. Call us now for a no-obligation discussion on 03330 11 22 55.
