Cloud Computing: The Software-Defined Revolution – Beyond The Hype
March 5, 2014
Grazed from InformationWeek. Author: Bill Kleyman.
The mist still settles from the burst of cloud computing. New marketing terms, new technologies, new infrastructure optimizations, and entirely new cloud delivery models could fill a dictionary with new acronyms. Infrastructure has evolved, giving us more physical resources to utilize, but a big part of advancements are due to breakthroughs at the logical, or virtual, layer.
This has led to software-defined technologiesof every shape and form. Some deserve an acronym, and some are jumping on the bandwagon. The challenge is to understand the different components that make up the SDX revolution, and how they fit together. You’ll also need to know how these technologies relate to the public and private cloud. Most of all, how do they affect your own datacenter environment, applications, and job?…
Software-defined networking (SDN) is of course the most widespread of the SDX technologies, involving thecontrol of data flow over local and distributed nodes. The idea is to utilize the software layer to manipulate how and where traffic goes within a datacenter. This can be accomplished at the virtual layer (think VMware and Nicira) as well as at the physical layer (a la Cisco and its NX-OS platform). These powerful network control mechanisms can take your datacenter traffic control methodology to a new level…
