I. Introduction of SD-WAN

SD-WAN refers to a new approach to building networks that focuses on speed, resiliency, automation, security, manageability and ease of use. Traditional routers have limited scalability, which means they can usually only connect to a few hundred clients at a time, and traditional WANs often experience latency issues due to design bottlenecks.

But with SD-WAN, enterprises can quickly deploy high-performance WAN services over any network infrastructure, including MPLS, broadband Internet and even LTE, meaning they can scale quickly without having to worry about managing multiple vendors or different types of hardware.

II. Benefits of SD-WAN

(1) Improved security

From a security perspective, SD-WAN is different from traditional WANs in that most IT organizations lack in-house talent with network experience and security skills.
Most SD-WAN solutions offer basic built-in security features, such as firewall and VPN capabilities, to improve user security. In addition, users looking for advanced security features can look for SD-WAN solutions that offer protection against data loss, downtime and liability, with popular SD_WAN solutions including next-generation firewall (NGFW), intrusion prevention system (IPS), encryption and sandboxing capabilities.

(2) Reduce operational costs

With the elimination of routers and other network devices, this is a cost-effective solution compared to older central radial networks. In addition, there is no need to dispatch technicians to install and maintain local networks, which for many enterprises would be prohibitively expensive for MPLS circuits. The total cost of SD-WAN, including hardware, software and support, is estimated to be two and a half times lower compared to traditional WAN architectures.

(3) Reduced Data Complexity

As small businesses use more technology solutions, such as local, edge and cloud-based applications, network complexity becomes a common issue due to competition for limited bandwidth, resulting in poor network performance and the potential need to hire more IT specialists on site to manage the local IT infrastructure, resulting in increased costs. SD-WAN provides a solution by monitoring and alerting on the performance of different data types to provide a solution to ensure adequate bandwidth is allocated, and users can configure SD-WAN to prioritize critical traffic through the most efficient path to improve performance.

In a nutshell, the simplification is that the data that before may only be understood by experts can now be easily understood by ordinary users with the explanation of SD-WAN.

(4) Centralized Management

SD-WAN helps simplify deployments and streamline network management functions, reducing staffing requirements for remote office network support, and with no traffic backhaul, your different locations can achieve greater bandwidth efficiency while enforcing security policies from a central source.

(5) Support for automation and orchestration

Improve IT productivity and total cost of ownership with cloud-based automation for management, service orchestration and visibility.
