VPN lockdown: Evaluating cloud vs. managed VPN providers
Virtual private networks (VPNs) are essential for protecting corporate data. As we explore in this issue of Network Evolution, the pressure to support an increasing number of mobile users and more advanced mobile use cases has created challenges for IT departments that lack the in-house expertise to meet VPN management demands. Managed and cloud VPN providers offer an alternative.
Meanwhile, software-defined networking has promised to eliminate many of the mundane administrative tasks that bog down network engineers. But will that increased automation and programmability eliminate their jobs as well? Probably not, according to several networking pros, who say their core skill sets are still in demand but acknowledge their roles are changing.
And finally, OpenStack is enabling engineers to automate and orchestrate network resources like they do virtual machines. The provisioning and management of these network resources can be integrated into the orchestration of the overall IT infrastructure.
