IT leaders are well aware that the fundamental difference is in the way that devices, users and endpoints that are connected to the network are managed. Traditional LAN provides basic connectivity to end users but does little to assure the end user experience or optimise business efficiency. SD-LAN, on the other hand, provides intelligent connectivity that focuses on the needs of the end user. It’s a cloud-delivered solution based on an application and policy-driven system, which means that the management approach is virtual, centralised and automated by default. What’s more important to understand is how businesses can benefit from an SD-LAN delivery. And in order to do that, we need to look at the drawbacks of LAN.
Traditional LAN architectures for medium and large enterprises use on-premise switch management and WLAN controllers for their wired and wireless LANs. This approach comes with its own obstacles:
All these challenges can put a brake on innovation, escalate your operational costs and increase risks around capacity and security management.
That’s where SD-LAN comes in. By moving the control layer to the cloud, centralising and simplifying network management and adopting a cloud architecture approach, you can deliver wider business improvements:
Since the pandemic, the number of hybrid working models has expanded as work is no longer seen as “a place” and people can access the tools they need for their jobs at home, in the office, on the move and thanks to guest Wi-Fi, at their favourite coffee shop or hotel. In fact, many employees now expect this level of flexibility, and these expectations continue to increase as new technologies become available.
Being cloud-based, SD-LAN is the perfect platform to help organisations keep up with these changing demands by providing centrally managed technology updates. IT teams can concentrate on running their business because SD-LAN takes care of troubleshooting faults, identifying problems and resolving them through the use of automated tools.
This new-found ability to rapidly develop and deploy SD-LAN software has paved the way for vendors to move beyond merely providing connectivity into new areas such as AIOPs (Artificial Intelligence for IT operations). This is great news for SD-LAN customers because automated IT decisions can be made without human intervention. And that means they can deliver better user experiences with less resources.
Analysts corroborate this in their reviews of the LAN and SD-LAN market:
“However, the enterprise wired and wireless LAN infrastructure market has evolved beyond its traditional role of merely providing network connectivity for devices. The market now comprises vendors delivering not only wired and wireless networking hardware, but also inter-related network management, analytics and security applications. This tight integration of network hardware and software delivers the mission agility, pervasive security and increased levels of experience required by end users across all types of connected applications and devices.” Gartner Magic Quadrant for Enterprise Wired and Wireless LAN Infrastructure, published December 2022.
A recent study by IDC in partnership with Vodafone Business and Juniper Networks on Agile Working showed that 62% of on/off-premises employees believe it’s important to have an office that feels social and creative. In this context, modernising the premises with solutions that put the users’ experience first is crucial to engaging and retaining talent. The development of AIOPs in SD-LAN allows IT teams to quickly troubleshoot Wi-Fi access issues at the client device level, resulting in improved employee user experience and productivity.
Another key aspect of SD-LAN is automation. Driven by intelligent technologies like artificial intelligence (AI) and machine learning (ML), SD-LAN provides deep insights and analytics to create patterns and automate policies and settings, as well as proactively recommended actions when any potential or actual issue is identified. This lets businesses free their IT teams, and optimise operations, network performance and user experience – while reducing costs. Customers with SD-LAN deployments combined with AIOPs have seen a significant reduction in trouble tickets and engineer site visits.
Vodafone Business has over 20 years experience in implementing and managing LAN, having sold to the public sector, governments and some of the largest enterprises in the world. We’ve partnered with Juniper Networks to develop and deliver our SD-LAN solution to meet the changing needs of our customers as they pursue their journey to the cloud. Our solution is a secure, agile and scalable network that helps you optimise operations, performance and user experience. Being an AI-driven network with centralised control, it eases the burden on your IT teams by proactively identifying issues and recommending solutions before they impact your business.
