How SD-WAN in the enterprise leads to greater security, integration and automation

Cloud and software as a service (SaaS) applications are great for businesses – but they need a solid infrastructure underpinning it. According to IDC, security, bandwidth optimisation and automation are key to more organisations analysing SD-WAN for their operations.

The study, which gauges the views of more than 1200 enterprises across 11 countries, assessed how software defined networking (SDN) is moving into the enterprise. According to the respondents, bandwidth optimisation was the most important reason for adoption, cited by 36% of those polled, alongside consistent application security (31%), integration with existing WANs (28%) and improved automation and self-provisioning (28%).

According to the research, while usage in both the United States and China is solid, use cases and deployment scenarios represent a ‘study in contrasts.’ Primary SD-WAN use cases for enterprises, according to the research, are the ability to simplify WAN infrastructure, use multiple WAN providers, and use broadband to offload non-critical business apps.

In one of the defining acquisitions of the year in this space, Cisco bought Viptela, a provider of SD-WAN technology, for $610 million (£471.9m) back in May. At the time, the two companies emphasised the importance of coming together to provide ‘next generation SD-WAN solutions to best serve all size and scale of customer needs.’

In its research IDC notes the importance of the changing face of the enterprise WAN. “Given the affinity towards leveraging broadband for enhanced capacity across enterprise sites, in parallel with the proliferation of cloud-based applications and services, the enterprise WAN is being rapidly rearchitected to cost-effectively deliver new, secure capabilities,” said Rohit Mehra, vice president of network infrastructure at IDC.

“Understanding and adapting current WAN network and security solutions across the emerging connectivity and application landscape is going to be a key ingredient for success as this market transforms in key geographies and across the service and solution provider domains,” Mehra added.
