While IT has big WAN challenges, including navigating a migration to MPLS and providing enough bandwidth at current spending levels, the biggest WAN game changers may be the cloud, both public and private.
While just 31% of more than 300 business technology pros surveyed by InformationWeek Reports have thus far altered their WAN strategies due to adoption of public cloud services, private and hybrid cloud will have a significant impact when deciding whether to keep the traditional hub-and-spoke design, provision business-class Internet links at some or all branch sites, or some combination of the two.
- 69% expect demand for WAN bandwidth to increase significantly (15%) or somewhat (54%) in the coming 12 to 24 months.
- 63% have no plans to deploy Cisco’s OTV technology.
- 44% of organizations that would like to upgrade WAN connectivity but are unable to do so cite expense as the biggest factor preventing it.
- 29% say their organizations are less vulnerable to WAN-based attacks and security breaches compared with a year ago.
“Ethernet is moving to take over the WAN, the same way it did the data center,” says Lorna Garey, content director of InformationWeek Reports. “While 69% still have T1/E1/BRI circuits in use, Carrier Ethernet is hot on ISDN’s trail with 61% adoption.”
