There are many advantages of SD-WAN. In this article, we roughly divide these advantages into seven aspects. Find out which advantages can solve the problems your enterprise is facing!

1. The most obvious advantage is to reduce costs and increase efficiency. SD-WAN can integrate dedicated lines, Internet, MPLS, 4G, 5G and other connection methods to effectively increase the bandwidth of the wide area network, while reducing the overall connection cost, achieving a double harvest of cost reduction and efficiency improvement.

2. Simplify deployment. Most SD-WAN hardware CPE devices support Zero Touch Provision, zero-touch deployment, and rapid deployment. For example, CPE devices can be configured through email or through pre-configuration. When an enterprise has many branches, these quick-deployment functions provide the basis for rapid business development.

3. Intelligent routing and link aggregation. SD-WAN can support a variety of connection methods, such as Internet, MPLS, 4G lines, etc., and can select routes based on the quality of the network. For example, if there are two Internets and one of them has poor Internet quality, the routing selection will take the Internet with good quality. Route selection can also be performed based on the quality of the network. For example, core applications are arranged to use MPLS lines, and low-priority applications are arranged to use the ordinary Internet. SD-WAN can also support link aggregation, bundling two or more underlying Internet roots together to greatly improve network efficiency.

4. Simplify operation and maintenance. The products of some SD-WAN manufacturers support real-time monitoring of link quality, in-depth application identification, easy configuration (graphical interface, one-click VPN configuration), and one-stop operation and maintenance reports. From an operation and maintenance perspective, these functions are very important.

5. Integration with security. The integration of SD-WAN technology and security technology is a big topic. Currently, many SD-WAN manufacturers can provide end-to-end security integrated solutions, data encryption and segmentation isolation.

6. Network quality optimization. In the SD-WAN network architecture, there are Underlay network and Overlay network. The Underlay network builds a tunnel on top of the Underlay network to achieve a more flexible network. When the underlying network becomes unstable or loses packets, SD-WAN players will make some optimizations in the Overlay network and activate the repair mechanism.

7. Accelerate access to the cloud. With the popularization of cloud computing technology, more and more enterprises have chosen to go to the cloud, and access to public clouds has become more and more frequent. SD-WAN technology can solve the problem of branches directly connecting to the cloud without having to go around the headquarters. At the same time, SD-WAN can also realize multi-cloud connections between public clouds and private clouds, cloud migration, etc., providing a fast lane for enterprises to quickly migrate to the cloud.
