Introduction
The speed with which digital transformation is happening across industries is putting significant strain on enterprise IT teams. To meet the demands of remote workers and their public cloud consumption, there is a widespread push to adopt next-generation technologies. SD-WAN is a distributed networking strategy that offers businesses a reliable substitute for hub-and-spoke network topologies with excessive latency.
The utilisation of IP security (IPsec), VPN tunnels, next-generation firewalls (NGFWs), and the micro-segmentation of application traffic are the main components of SD-WAN security. To keep up with changing security threats and to manage the expense of updating and upgrading security components, security network functions must be virtualised. The use of virtual machines by SD-WAN security allows software updates to be placed on existing hardware, rather than new hardware being installed for each update - thereby saving time and money. SD-WAN solutions should include a high availability, centralised console for monitoring and controlling SD-WAN connection health, quality, and resource allocation. This console should provide on-premises usage and demand metrics, as well as connectivity to core networks, cloud infrastructure, and branch-level networks on the premises. It should provide visibility into branch data output, Internet bandwidth-using applications, QoS Priority performance, and individual link performance.
Core Benefits of using SD-WAN
Cloud-ready WAN
Ease of Migration
Better Network Management
Works with Multi Transport
To function properly, all cloud technologies require a high-speed, low-latency internet connection. Connectivity for businesses using traditional WAN technologies such as MPLS, was limited to whatever fixed-line connectivity their MPLS provider could offer - usually expensive Fibre Ethernet, unreliable Fibre Broadband, or sub-par traditional broadband. With SD Wan, businesses can select the best coverage to each site and take advantage of new Full Fibre and Mobile LTE technologies alongside the tried and tested Fibre Ethernet - instantly boosting cloud performance and presenting huge bandwidth cost-saving opportunities.
One significant advantage of SD-WAN is that it does not require any change to your existing network. SD-WAN can be phased in as a parallel overlay network to simplify your overall network architecture and management. Sites are migrated in stages based on their type, location, or any other priority sequence you may have. Secure connections can now be established in minutes rather than days or weeks. Employee voice, messaging, video, collaboration, file sharing, and more are made available on desktops and mobile devices after being authenticated to the network and applications and managed with policy, driving down operational costs while improving security and availability.
SD-WAN technology enables completely centralised network management. They simplify network automation and provisioning via web-based consoles, allowing network managers to detect network changes and orchestrate any new or modified network configurations that are required. Network administrators can also easily and consistently configure and deploy hybrid WAN links using centralised web-based interfaces, regardless of the type of underlying connectivity. Users can simplify network management by creating application-specific, performance-based policy routing. The dynamic routing capabilities of SD-WAN technology allow it to route around performance issues until the connection is restored or performance stabilises.
SD-WAN technology allows administrators to deploy a policy across the entire network. These policies continuously monitor traffic flow and performance and enable the network to adapt to changing network conditions. An SD-WAN architecture is provider and transport independent, which means that the organisation can use any type of transport or provider as long as the provider connects to a shared network (the Internet). For example, regardless of the WAN technology you currently use, you can initially deploy SD-WAN on your existing network (i.e., MPLS, DMVPN, VPN). Organisations today require a solution to virtualise the security network function in order to combat rapidly evolving security threats while maintaining control over the CapEx of updating and installing new hardware.
What can SD WAN do for your company?
A well-designed SD-WAN solution can change the course of an organisation giving a real-time view of the network since it gives businesses a level of flexibility and control and this makes it an agile solution.
The advantages of migrating to SD-WAN are numerous. Different factors may influence your SD-WAN transition and overall network performance, from conducting a thorough site survey to preparing adequate bandwidth.
