  • The first place to tackle SDN? In the WAN

    By John Dix | 23 January, 2015 03:25

    Disruptive innovation in infrastructure is on the rise, and nowhere is that more evident than in the Software Defined Networking movement. But while much of the SDN discussion has focused on the data center, the better initial use case might be in the wide area network. One advocate of that approach is Michael Elmore, IT Senior Director of the Enterprise Network Engineering Infrastructure Group at Cigna, a global health service company headquartered in Bloomfield, Connecticut. Michael is also on the board of Open Network Users Group (ONUG). Network World Editor in Chief John Dix asked Elmore to participate in an email-based Q&A to explore the promise of Software Defined WANS.

    Last week, I submitted an expense report to a client. The accounts payable representative made me revise the report four times to put things in the right buckets and correct a $1.04 error. (Really.) Of course, I can't charge anybody for his or her time, and the A/P department is really busy because it's "understaffed." (Uh-huh.)

  • Create Magical Vendor Presentations Using Analytics, TED and Steve Jobs

    By Rob Enderle | 14 March, 2014 12:39

    The best TED speakers, channeling Steve Jobs, are dynamic, engaging and moving. Meanwhile, analytics technology can provide near-real-time feedback on whatever you want, including audience (dis)engagement. So why are so many tech industry events just more of the same?

  • Incremental SDN: Automating Network Device Configuration

    By Ethan Banks | 09 September, 2014 23:39

    The definition of Software Defined Networking (SDN) continues to broaden, today including functions such as configuration automation and orchestration. While these tasks aren't strictly SDN, the fact is software is used to define some aspect of the network infrastructure in both cases, so vendors have stretched the definition of SDN to bring configuration automation and orchestration platforms into the mix. In fairness, the line gets blurry, as some modern orchestration systems use programmatic interfaces to provision the network instead of traditional configuration tools such as SSH or SNMP.

  • A common theme in identity and access management failure: lack of Active Directory optimization
