Enabling the quick response to changing requirements of the clients/businesses by shaping the traffic from a centralized console without the need to upgrade the infrastructure network. c. Offering better scalability and security by building on the potential of SDN and SD-WAN as compared to a traditional LAN. d. A small business that uses a simple infrastructure network with minimal traffic must use SD-LAN cloud computing providing the benefits of flexibility, automation, security, and reduced operation cost.
