Access "Software defined networking for the private cloud network bottleneck?"
This article is part of the October 2012 Vol 3, No. 5 issue of Are SDN solutions the answer to private cloud bottlenecks?
You've heard it before, but it bears repeating: Networks are bottlenecks in the private cloud. Server and storage technologies have evolved into pooled resources that cloud administrators can spin up on the fly, but networks remain manual. To be more agile, private cloud networks must be virtualized, and software defined networking offers a cost-effective method for getting there. "wEnterprises need to be like service providers and react as quickly as they can for internal customers. They need to enable self-service IT. The biggest roadblock to that is networking," said Ben Cherian, chief strategy officer with Midokura, a Japanese startup that is developing SDN-based network virtualization technology. "Armies of CCIEs are running around making little changes to switches and routers that have requisition times of weeks," he said. Meanwhile, in many cases cloud providers can click a button to make changes. Essentially, SDN technology decouples and centralizes the control plane from the data-forwarding plane of individual network devices. By centralizing that ... Access >>>
