The Self Operating Network

by Derick Winkworth 

Software Defined Networking has passed through its first major cycle. Many associated ideas have been consigned to the trash bin of history, while many other ideas have either evolved or sprung anew. As a network engineer I really hoped, back in 2011, that SDN would address many of my day-to-day challenges. With very few exceptions, this did not happen. In fact, within the SDN movement there was open disregard for network engineers. They were often referred to as the “mainframe” engineers of the day. Six years later, most network engineers are still doing their jobs and SDN has not had an enormous impact on their day-to-day work. Interfaces and methods may have changed, but the complexity and day-to-day firefighting remain. As a network engineer, I must admit that much of this problem is our own fault. Let’s talk about what some of our challenges are. (more…)

How Next-Gen Analytics and Verification Helps Realize Resilient, Secure Networks

by Brighten Godfrey

At the ONUG Fall 2016 conference in New York, one theme struck me: the community realized more than ever the need for advanced analytics and verification. A poll of IT users at the event, for example, highlighted that the siloed nature of current monitoring solutions prevents them from understanding the entire network, end-to-end. (more…)

Seeking Truth in Networking: From Testing To Verification

by Brandon Heller

Sharp network admins already verify the network in a variety of ways, right?  Pings, traceroutes, and custom scripts verify expected connectivity.  Link and CPU utilization monitoring programs verify normal operation.  Maybe pushed configs are read back in to verify that the device accepted them.  And isn’t verification just another term for testing, anyway?

There Are No Private, Public, or Hybrid Clouds—Only Islands of Infrastructure to be Consumed

by Bruno Germain

At the root of John Boyd’s “OODA loop” methodology, there is the notion that we need to acknowledge and work with levels of “uncertainty”—gaps that result when applying established models to new and changing contexts[i]. Unfortunately, the networking community—desperate for operational stability—largely ignores these mismatches, designing network and security architectures as if they can dictate how applications are deployed.

Apps are On the Move, What’s a CIO to Do?

by George McGregor 

People have been on the move for a while – workspaces, applications and data are increasingly accessed from mobile devices. This has had a big impact on application delivery.  For any business these days, its all about apps and its all about the customer experience delivered by these apps.  (more…)

The New IT Culture, Skills, and Organization Needed for Hybrid Cloud Environments

by Dr. Robert B. Cohen

In the move to hybrid infrastructure, the ability to commit new code faster and run new applications quickly gives agile firms an advantage in deploying new services. These innovations change the skills required for new jobs and enhance the role of developers. During the move to DevOps and containers, firms have created work teams or collaborative groups. They replace the more time-consuming, rigidly structured organizational design employed to develop monolithic software, where each level in a multi-stage process had to complete and sign off on its contribution. This was time consuming, often taking up to 25 to 90 days for a new application to be run. (more…)

An Open Welcome to Open Networking

by Ahmad Zamer

From cloud computing to the Internet of Things, the global digital economy has created new realities that require new demands and increased scaling for IT and data centers. Thriving in the new world requires adapting to the new realities and quickly. Open networking offers enterprises a path to building cloud data centers that offer competitive advantages and lower operating costs.  (more…)

Digital Transformation Needs Fundamental Rethink of Networking

by Milind Bhise

$500,000. That’s the current approximate cost of a taxi medallion in New York City. Just a couple of years back it was over a million dollars. Share of trips of New York City’s Yellow Taxi has dropped from 84% in April 2015 to 65% in April 2016 (Source: NYC Taxi and Limousine Commission and Morgan Stanley Research). Is it the Uber-Lyft effect?  (more…)

The Hybrid Evolution of IT

Lee Calcote

“It’s a great time to be in Information Technology.” While this is a true statement, not everyone clearly understands why (or perhaps, has the fortitude to make it so). In the face of a massive movement to public cloud—by 2020, 92% of world’s workloads will be in cloud—68% in public and 32% in private[1]—many in IT feel their value in the workplace eroding along with their identity. This feeling doesn’t need to be reality. Businesses are changing the way they operate and are transforming to leverage information technology more strategically. IT has a real opportunity to lead this transformation, not let the transformation happen to them.
