An IDG survey of IT decision makers finds substantial disparity on the best strategy to connect non-HQ locations to the cloud. Hybrid WANs and SD-WANs are now leading the way, with 40% of respondents saying they are pursuing ways to adapt or bypass the traditional enterprise WAN.
End-user productivity and collaboration needs, IT strategy and digital transformation initiatives are driving growing reliance on cloud-based applications in branch and satellite offices. Just 3% of survey respondents favor accessing these applications through the traditional backhaul process to the corporate network hub via the WAN.
Instead, 37% favor a hybrid or software-defined WAN (SD-WAN) approach to meeting future needs of these non-HQ locations. Market research firm IDC projects the worldwide revenue of $8.05 billion for SD-WAN infrastructure and services in 2021.
“The increase in SaaS adoption for business applications throughout the enterprise disrupts the prominence of MPLS-based WAN connectivity to the branch,” says IDC. “SD-WAN is increasingly leveraged to provide dynamic connectivity optimization and path selection in a policy-driven, centrally manageable distributed network architecture.”
In the survey, 31% view direct connection to the cloud via business ethernet as the preferred option for branch connectivity. But SD-WAN may be the ultimate hybrid WAN option, because it can route to cloud providers dynamically via the best path available based on application needs and cost considerations.
