The worldwide SD-WAN market grew 45% in the third quarter of 2021 compared to the previous year, according to the Dell’Oro Group, recording record revenues of $2 billion.
“Enterprises are upgrading network infrastructures at accelerated rates compared to pre-pandemic times, and our research finds that the SD-WAN market is growing at strong double-digit rates in all regions of the world,” explains Shin Umeda, Vice President at Dell’Oro Group. “Because SD-WAN is software-based technology, the global supply chain disruptions have had less of an effect compared to hardware-based networking products.”
Demonstrating SD-WAN business value
Enterprises fast realize the importance of SD-WAN to handle increasingly distributed and complex network infrastructures and the trend for hybrid working. SD-WAN provides centralized management, flexibility, performance capabilities and security that work within an any-place, any-device, cloud-first business strategy.
According to IDC, there is little doubt that SD-WAN infrastructure is a compelling technology for any enterprise looking to improve WAN reliability, optimize network performance and user experiences for applications accessed via the WAN, or reduce costs or avoid future cost increases on WAN connectivity.
“As organizations look to support a hybrid workforce and cloud-native network architectures, SD-WAN infrastructure has become a critically important technology for enabling flexible, agile and optimized connectivity,” explains Ajeet Das, Research Director for Carrier Network Infrastructure at IDC. “Enterprises will continue to invest in SD-WAN capabilities for years to come as they look to enable secure connectivity for users to applications no matter where they’re hosted.”
Key components of an SD-WAN infrastructure include a centralized policy controller, automatic management of hybrid WAN connections, dynamic path selection of application traffic, and optional programmability, security, and analytics of wide-area network (WAN) traffic.
The future is SD-WAN
The SD-WAN vista is transforming fast. Once an enterprise has deployed SD-WAN, there is no shortage of additional enhancements around security and efficiencies, for example, to provide a competitive edge.
Enterprises that haven’t made a move to SD-WAN will need to put it on their roadmap or suffer a dent in their bottom lines. As Jan Hein Bakkers, Senior Research Director at IDC explains: “A successful path to the future enterprise will require WAN transformation. SD-WAN will be at the heart of this transformation.
