In the present world, many businesses rely on cloud and SaaS Solutions. Software-Defined Wide Area Network (SD-WAN) is a reliable solution that has quickly replaced traditional WANs. It simplifies the design and management of networks. SD-WAN is excellent for enterprise networking. It makes it possible for companies to reach a wide geographical area and multiple carrier networks.
One of the biggest challenges that remote workers face is finding a network that covers a large geographical area and various carrier networks. SD-WAN addresses those problems. Its networking hardware is separate from the control mechanism. The revenue for SD-WAN vendors is growing at about 59% every year. On average, SD-WAN infrastructure will have a Compound Annual Growth Rate of 32.7% in the next three years.
The implementation of SD-WAN technology varies from one vendor to another. However, the primary feature is that it allows customers to create single-network infrastructures. They include connection types such as wireless LTE, multiprotocol label switching (MPLS), or broadband. Using this technology, you don’t need to waste money on private MPLS connections.
It allows your business to switch your wireless infrastructure and transports depending on your bandwidth availability. You can quickly spin up new connections to different remote locations.
Companies that use SD-WAN don’t need to use costly routing hardware. Instead, they can use the cloud. It increases flexibility and connectivity.
One of the main reasons why SD-WAN is the best option for remote workers is that it improves connectivity from different locations to the cloud and the main office. Because of their flexibility, businesses can reduce their WAN expenses. It is a powerful tool for managing traffic, and it has higher visibility.
Many companies find it challenging to get Return on Investment for SDN in the data center. SD-WAN fixes the problem. It offers immediate and significant ROI. With SD-WAN solutions, you can augment or replace MPLS connections with broadband internet services. SD-WAN can save you up to 90% of WAN costs.
If you have a centrally-managed SD-WAN architecture, your OPEX is low as well. You can bring a remote location online in a few minutes. The process is simple and does not require the help of IT experts.
Even though SD-WAN is excellent, it is not a substitute for WAN optimization. You still need WAN optimization to improve your application performance over large distances. WAN optimization makes it possible to transport large sets of data with no problem.
The benefits of WAN optimization include reducing latency and improving application performance. Even with SD-WAN, techniques like protocol acceleration remain the same. Its main advantage is to help companies manage the complications that arise from cloud adoption. According to the Frost & Sullivan 2018 SD-WAN survey, 67% of IT experts still find WAN optimization to be necessary. They feel that SD-WAN works best when combined with WAN optimization.
In conclusion, SD-WAN is a timely and impressive solution to the pressures of the cloud-era enterprise network. Some of its benefits include flexibility, a lower WAN OPEX and CAPEX, and the ability to reach multiple carrier networks. SD-WAN gives your company new levels of visibility for configuring, control, and the provisioning of network resources.
