How the Cloud is Driving SD-WAN

The adoption of Software-Defined Wide Area Networking (SD-WAN) is increasing, providing enterprises with a host of benefits. 451 Research reports that one in five companies indicate that they’ll adopt SD-WAN in the following year, and an additional 30 percent say that adoption of SD-WAN is on their radar.

The benefits of implementing SD-WAN include:

  • The ability to optimize connections to the cloud and secure those connections better than with current networks, which is a key driver of SD-WAN use
  • An application-aware approach to WAN, which is becoming more important to IT managers as cloud usage expands
  • Improved agility and cost-savings

Cloud Adoption is Spurring SD-WAN

The migration of companies’ software solutions to the cloud is an independent event, but the use of SD-WAN is occurring alongside it. As IT professionals pursue a transition to cloud software, they don’t want to sacrifice performance or security in seeking out the cost savings and agility that’s found in cloud applications.

A traditional WAN is set up with individual branches connected to a central location using a Multiprotocol Label Switching (MPLS) connection or other dedicated circuits. Each branch has a router that acts independently, and traffic on the connection is managed based on static routing.

SD-WAN, by contrast, removes the control plane from the physical devices that are at each branch, which provides central control and visibility over the WAN. This means that enterprises are able to mix and match the connections that are being used and the various carriers, allowing for greater flexibility and agility.

This set-up trades a wheel-and-spokes structure for one where the enterprise can connect directly to the cloud. Additionally, IT professionals have more visibility to work with the entire network footprint and manage traffic for optimized cloud application performance.

As cloud migration continues to increase, it’s expected that SD-WAN will grow alongside it. The same 451 Research poll results indicate that 88 percent of respondents plan to increase their cloud and hosting budgets in 2017.

What’s Holding You Back?

There are some potential obstacles to implementing SD-WAN, and one or more may keep your company from embracing this technology:

  • The cost of new equipment that SD-WAN requires
  • Concerns about the maturity of the current offerings for SD-WAN
  • Internet performance
  • Security concerns

Some experts predict that cloud offerings may soon be bundled with SD-WAN, because the marriage of the two makes sense in nearly every situation.
