We are surrounded by acronyms and buzzwords in technology. SD-WAN is one that is often used in the industry nowadays.
Organizations embrace digital transformation to stay up with market developments, consumer needs, and competitiveness. Traditional network designs weren't meant to manage digital transformation workloads and complexity. Business-critical services are commonly spread over numerous clouds, compromising network performance, particularly at branch sites.
Smart network operations teams opt for SD-WAN. SD-WAN reduces overhead and improves network performance. Routing and hardware expenses are saved through SD-WAN solutions while allowing multi-cloud access. SD-WAN also reduces overhead and supports new digital apps and services. This new technology streamlines WAN administration and operation and brings corporate advantages.
Business Challenges that SD-WAN Addresses
There has been a dramatic increase in the pressure on the network as a result of digitalization. Businesses must now rely on a stable and secure network, which conventional router-based network topologies are incapable of providing. An SD-WAN solution assists businesses in addressing use cases in order to expedite digital transformation efforts, lower cybersecurity risks, and increase revenue.

Safeguards IoT devices using a zero-trust network
-
Helps in complying with the cybersecurity framework of the National Institute of Standards and Technology (NIST).
Ways SD-WAN Can Help Businesses Boost their Bottom Line
Digital transformation is a double-edged sword. It can increase consumer satisfaction and market reach, but can pose security threats. According to the U.S. State of Cybercrime study, 41% of respondents stated more
cybersecurity occurrences in 2017. The good news is that many SD-WAN solutions provide built-in security. Most SD-WAN systems only offer basic firewall and VPN functionalities, requiring IT teams to add security to elastic and dynamic SD-WAN connections after the fact. SD-WAN solutions with NGFW, IPS, encryption, AV, and sandboxing can avoid data loss, downtime, regulatory violations, and legal liability.
Cloud services are rapidly being used by businesses. The great news is that SD-WAN enables direct cloud access at the remote branch, removing backhauling traffic – which routes all cloud and branch office traffic through the data center – allowing workers to directly access cloud applications irrespective of location without burdening the core network with additional traffic to manage and secure. Furthermore, SD-WAN enhances cloud application performance by prioritizing vital business apps and allowing branches to interact directly with the Internet.
As businesses deploy a growing number of cloud-based services, the volume of data traveling across a WAN rises dramatically, driving up operational expenses. SD-WAN, thankfully, can minimize this cost by utilizing low-cost local Internet connectivity, offering direct cloud access, and lowering traffic via the backbone WAN. According to an IDC poll (prediction), over a quarter of survey respondents anticipate SD-WAN cost reductions of up to 39%, with the other two-thirds anticipating more modest savings of 5–19%.
Data transfer over a network isn't created equal. Fortunately, SD-WAN can be set up to prioritize business-critical traffic and real-time services such as Voice over Internet Protocol (VoIP) and then successfully guide it over the most efficient path. IT teams can help decrease packet loss and latency concerns by supporting important applications over dependable, high-performance connections, increasing employee productivity and morale. This is business-impacting performance.
Closing Note
Indeed, SD-WAN evolved and flourished in the
data center over the first few years of development. However, the time has arrived to take it seriously as a tool for managing your wide area network. There are currently several vendors on the market, as well as several mature solutions to choose from. More significantly, the business cases for SD-WAN are expanding on a daily basis.
