Adopting SD-WAN Experience to Improve Business Performance

SD-WAN simplifies WAN operations by dynamically steering and redirecting traffic to improve application performance. It also offers redundancy among WAN connections, automatically switching to a backup path in case of failure or congestion. Businesses that adopt SD-WAN experience a variety of cost and bandwidth benefits. For example, they can use less expensive public or private broadband links instead of leased MPLS circuits.

How It Works

SD-WAN is a technology that uses software to operate a mid-sized to large-scale computer network spread across locations. It relies on internet-based communication tunnels, software-driven network encryption, firewall software and more to run the system.

SD-WAN abstracts the different connectivity options – like multiprotocol label switching (MPLS), mobile and broadband – to create a virtual enterprise vast area network (WAN). It provides a more cost-effective way for organizations to connect their branches and remote sites to the data center via inexpensive and reliable internet connections.

The software-based approach to WAN configuration can deliver automatic traffic steering and bandwidth allocation based on current network conditions, application requirements and user demand. The software can also monitor a business’s WAN performance and automatically redeploy resources to ensure that business-critical applications continue to work as usual if there are degradations in network availability or latency issues.

Another significant benefit of SD-WAN is optimizing applications based on bandwidth requirements and latency levels. It helps users avoid experiencing disruptions in connection, such as WAN blackouts or slow internet speeds that can interrupt their workflow.

Moreover, the basics of sd-wan is a good fit with cloud computing and other services that use the internet for communication, such as software as a Service (SaaS). It reduces the cost of implementing and maintaining the infrastructure. It provides greater flexibility to users because they won’t have to worry about missing important files if their internet connection goes down.


SD-WAN combines many security measures and procedures into one solution, making managing security policies across the network easier. For example, an IT team at a central office can create a security profile and automatically distribute it to devices throughout the network. It enables the creation of a single security policy that can be applied to various hardware, such as switches, routers, firewalls, and WAN connections. Additionally, it speeds up the deployment of security rules and policies. In addition, the centralized control plane of SD-WAN allows you to make changes to security policies and automatically roll them out to all devices on the network at once. It can significantly speed up the security planning process.

It also ensures that devices have the correct security settings, reducing the chances of rogue devices being added to your network. It is essential because some end users assume they can add a network device to their LAN or WAN without authorization. In addition to protecting corporate traffic, SD-WAN enables remote workers to connect directly with cloud applications like Office 365 and CRM systems. It is essential in industries heavily reliant on cloud services, such as financial institutions and healthcare providers.


If you’re planning to deploy SD-WAN, it’s essential to take the time to create a comprehensive plan. This step will help your team prepare for a successful implementation that meets your business’s needs and avoids costly mistakes. A good SD-WAN implementation plan will address the network’s significant components, including connectivity, routing, security, and management. It will also include a testing phase to ensure all elements work correctly. Using pre-defined configuration templates, next-gen SD-WANs enable organizations to streamline their deployment processes and minimize errors by automating everyday tasks. These templates use workflows that combine classes of service to steer traffic, define service chains with a simple drag-and-drop, and automate network configurations to eliminate errors that can degrade performance and even cause network failures.

Next-gen SD-WANs also support micro-segmentation, allowing IT to separate traffic by class and data type. It enables IT to control access and reduce security vulnerabilities across the LAN, WAN, cloud, and data center. When evaluating potential vendors, ask about the ease of zero-touch provisioning and popper planning and how easy it is to implement traffic handling policies for each WAN interface. You should also evaluate the functionality of a network monitoring system, such as failure scenarios and alerting mechanisms.


SD-WAN technology reduces costs and improves security by connecting multiple locations using one network connection. It also allows businesses to leverage the cloud and other cloud services more effectively by improving application performance and delivering a seamless on-ramp to the cloud. It uses WAN optimization techniques to improve traffic and bandwidth efficiency, reducing latency and increasing throughput by automatically redirecting traffic to the fastest, most reliable path. In addition, it can automatically failover to a backup connection if the primary is unavailable. The software-based technology eliminates the need for traditional routers, which use routing tables to determine data forwarding decisions. Instead, packets are given labels and paths matched with their destination using AI-based machine learning algorithms.

Organizations can save on WAN infrastructure and maintenance costs by eliminating the need for leased MPLS circuits. Additionally, SD-WAN helps to improve business productivity by allowing mobile workers to access corporate resources from anywhere. It can also simplify deployment at remote offices by removing the need for specialized IT skills at each site, lowering OPEX. This cloud-based, centrally managed architecture makes it easy to deploy new sites quickly. It would be great to have a solution for managing and orchestrating your hybrid cloud architecture from a single platform to get the most out of your SD-WAN.
