“The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.” – William Arthur Ward
Data center and network infrastructures are going through radical changes due to the confluence of customer and technology provider-driven initiatives. Some of these initiatives include unified networks, virtualization, cloud services, and personal devices in the workplace (BYOD). In order to address these challenges, programmable networks are being touted by just about every networking vendor, including the “Big Kahuna,” Cisco, who, like virtually every other vendor, has much at stake with the coming changes.
Today’s networks make it nearly impossible for vendors to realistically meet all of their customer’s needs, due to problems associated with management, agility, performance, and mobility. Additionally, ever-increasing capital and operational costs add strain to already compromised resources. However, Software-Defined Networking (SDN) promises to change all of that with a network architecture that enables vendors — as well as network providers, cloud operators, and solution providers — to build networking solutions that are easier to manage, perform faster, are more agile and secure, and are more cost efficient.
SDN promises to deliver broad architectural changes through an extensible service delivery platform that can be used by enterprises, service providers, and cloud operators. Through an open, automated, and autonomous architecture, IT organizations will deploy SDN to simplify management and gain end-to-end control of compute, storage, network, virtual machine, and operating system resources and tasks.
If you are a vendor who makes networking products, be advised, and prepare to adjust your sails to maximize the winds of change. Support these new architectures that promise to deliver powerful and positive changes to network infrastructure.
