SDN and the Data Center of the Future


Despite some recent obituaries published by my peers, software-defined networking is not dead. But perhaps certain aspects of it are dead or dying. If that’s the case, I say: “SDN is dead.

I welcome the ONF’s reset and believe it bodes well for the industry’s future. When OpenFlow Was King The ONF was born six years ago as a nonprofit consortium charged with the standardization and certification of OpenFlow, [...]



Redefining the Branch Office With SD-WAN


Editor’s Note: This blog post is sponsored by Citrix. The ideas and analysis are entirely the authors own. The days of homogeneous branch offices connected to a one-size-fits-all wide-area network (WAN) are over. Enterprises are redefining their branches, and this transformation requires a new approach to the WAN. EMA believes that software-defined WAN (SD-WAN) solutions [...]



Cisco’s Big Data Analytics Vision: Some Data Will Be Distributed Forever


Champions of big data analytics extoll the virtues of massive data stores. Enterprises have so much unstructured data that could help them improve operations and generate new revenue, they say. The more bytes, the better. Some might assume that enterprises will simply push every byte they can find into a Hadoop cluster or data warehouse. [...]
