Internet_Abstract.jpgMicro-segmentation is nothing new. We started talking about the concept a few years ago, with the onset of software-defined networking technologies like OpenFlow. More recently, micro-segmentation was most often associated with establishing trusted connections between cloud-based workloads.

The economics of SD-WAN and NFV

Posted: April 07, 2016   /   By: Dan Conde   /   Tags: Networking, SD-WAN, nfv


Software-defined WAN and network functions virtualization offer clear and simple cost-containment benefits.

Nothing beats direct economic benefit when adopting new technologies.  That’s why I continue to focus on software-defined WAN and NFV adoption in 2016.

It’s easy to tout some new technologies because they’re cool (nice technical implementation!) or make vague management agility claims. But ultimately, if they do not deliver outcomes, these products are pretty much useless and may remain as shelf-ware as some crazy-pants technology purchased for the wrong reason. I’m not saying that they’re not useful. It’s just that they are not supremely simple for consumers to understand and benefit from.

NFV, Telecom, and Enterprise: We know what we are, but know not what we may be

Posted: May 19, 2015   /   By: Dan Conde   /   Tags: Cloud Computing, Networking, openstack, nfv

153756157_jpgI attended the NFV World Congress, and I found the continuation of the increased intersection between Enterprise and Telecom Carrier Ecosystems. Traditionally, the world of telecom has been about signaling, switching circuits, radios, and the like. The introduction of NFV (network functions virtualization) had nudged the telecom world closer to the land of data center networking and cloud computing.
