How Small Business Benefit from SDN?

By Enterprise Networking Mag | Monday, October 07, 2019

Small organizations leverage SDN for better visibility, security, and efficiency in the network.

FREMONT, CA: Currently, businesses embrace software-defined networking (SDN) as a way to automate operations, enforce consistency, bring flexibility, and reduce troubleshooting times. As the SDN matures and refocuses, more small businesses can learn from its benefits. SDN structure traditionally targeted the organizations with large data centers or hundreds of network devices, as they were most expected to gain the benefits. When SDN first emerged, the conventional thought was that the businesses would understand the benefits of SDN if they ran thousands of network devices. But, this outlook changed over time. Along with this, the definition of SDN broadened beyond the early structure, which focused on managing Layer 3 switch infrastructure. The SDN expanded beyond the hardware and focused towards the soft-centric view.

Better visibility: Businesses can more easily see routing, switching, remote access, wired and wireless components, as well as threats and attempted incursions from the outside. A single SDN controller makes it easier to identify issues and, more specifically, enables them to translate it for nontechnical staff. Earlier, small businesses had little on-site IT so that SDN tools can help abstract networking into more understandable actions. For instance, wireless traffic will ultimately travel over wires. Seeing the whole chain helps pinpoint issues faster than trying to correlate data over multiple consoles.

Better efficiency: A significant benefit from the SDN is it shortens the troubleshooting time. SDN consoles help the small businesses with no in-house IT support or less technical staff and recognize the issue, or at least rule out the possibilities. This sorting helps reduce troubleshooting time, thereby maintaining or increasing productivity, sometimes even before a technician can make it on site. The SDN controller can even reside in the cloud, enabling a remote support organization to monitor from anywhere, even if the network is not accessible.

Better security: The majority of the security problems emerge from the inconsistent application of rules. Likely, a poorly executed rule will accidentally risk the resource than a hacker outside the firewall. SDN centralizes the features and automates their supply across the network. The SDN controller will then write the instructions out to all the appropriate devices, ensuring consistency and accountability.
