Although all networking of all types can benefit from SDN (Software Defined Network), one area ripe for adoption is the wide area network (WAN). SD-Wan, as software-defined WAN is called, can enable businesses to harness virtualization and reap the benefits. Some companies are pushing forward with SD-WAN technology and giving businesses an easy adoption path. Below is the rest of the Benefit of network based Software Defined WAN (SD-WAN):
Security
Unlike traditional WAN solutions, which handle security through multiple appliances at each branch office, SD-WAN can include all of these functions in-box and at the lower cost. SD-WAN can integrate with a cloud web content filtering service, too, and offer malware defences and botnet command-and-control intervention for every branch and remote devices.
Reliability
MPLS networks typically offer highly reliable packet delivery. Internet uplinks, on the other hand, often fail. To compensate for this fact, many organizations that move entirely to SD-WANs choose to order multiple internet links from different providers to maintain “four nines” (99.99 percent) availability in the case of link failure, link redundancy and link failover for business continuity and disaster recovery (BCDR).
Performance
SD-WAN technology can speed up your applications no matter where they are hosted. An SD-WAN, with built-in WAN optimization, improves performance for all mission-critical applications, hosted on-premises or in the cloud. And if you choose an SD-WAN delivered as a service over a private network, you can realize consistent application response times for users anywhere in the world, and sidestep the performance problems that plague SD-WANs that use Internet transport.
Adoption
Distributed organizations, as well as those moving toward the adoption of IoT technology, should evaluate SD-WAN solutions in terms of ease of use, manageability, ability to integrate with existing MPLS networks and the intelligence to automatically adjust traffic flows to accommodate network conditions.
Bandwidth costs
SD-WAN reduce bandwidth costs by leveraging inexpensive services, such as Internet broadband, whenever possible. They can still use dedicated Internet access (DIA) for higher uptime and performance. (DIA is often more expensive than broadband but less than MPLS and comes with some service guarantees.)
