Cumulus does container networking the right way

About a month ago, someone asked me to define the term “digital transformation.” At first, I thought about giving a long technical definition that mentioned the convergences of people, process and data, but then I shortened to one word — speed. Digital transformation is all about doing things faster than the competition. This is one of those things that’s easier to say than do. Most businesses simply can’t move faster just because they want to. Instead it requires an entirely new approach to IT. Gartner uses the term “Mode 2,” but other terms are things like agile development or DevOps. + Also on Network World: Adapting the network for the rise of containers + This new approach to IT has brought with it several new technologies, one of which is containers. The use of containers has steadily increased because IT departments can quickly spin them up, do whatever task they need to do and then shut them down. The whole process can be automated, so the IT organization doesn’t even need to be involved. To read this article in full or to leave a comment, please click here

IT powerhouses try to come from behind in enterprise IoT

It’s unusual for technology vendors of sufficient size not to be the most powerful companies in any market space they enter – the mere fact that they’re there arranges other players into a “Google/Microsoft/Amazon against everybody else” formation.That’s why, according to experts, the heterodox, wide-open IoT platform marketplace is so strange – it’s an area in which all the traditional powerhouses of IT are playing, but they’re not dominating market share the way they usually do.+ALSO ON NETWORK WORLD: How Google is speeding up the Internet + Cisco brings its SDN to Amazon, Microsoft and Google’s public cloudTo read this article in full or to leave a comment, please click here

Worth Reading: IPv6, large packets, and DNS

It appears that rather than effecting a slight improvement from IPv4, the manner of fragmentation handling in IPv6 appears to be significantly worse than IPv4. Little wonder that there have been calls from time to time to completely dispense with packet fragmentation in IPv6, as the current situation with IPv6 appears to be worse than either no fragmentation or the IPv4-style of fragmentation. —Geoff Huston @ potaroo

AfPIF Day Two: Identifying Challenges and Opportunities

AfPIF Day Two Summary 

The second day at the Africa Peering and Interconnection Forum (AfPIF) is dedicated to plenary presentations and discussions between the technical community, private sector, and government representatives.

The discussions aim to foster understanding of the landscape the various players operate in, the challenges faced, opportunities and ways to create synergies that guarantee increased connectivity, and exchange of content within the region.

The first session of the day was the formal opening ceremony, with Yves Miezan Ezo, representative of the Conseiller Technique du Ministre de la Communicatiln, de l’Economie Numerique et de la Poste de la république de Cote d’Ivoire, Caliste Claude M’Bayia, representative of l’ARTCI, and Moctar Yadaly, head of Infrastructure and Energy at the African Union Commission (AUC).

In his speech, Dawit Bekele, Head of the Internet Society Africa Bureau, welcomed participants to the 8th AfPIF session, noting that great strides have been made in Africa’s technology landscape, and it will get better.

The first AfPIF session was held in 2010 by the Internet Society out of the realization that too much African Internet traffic was exchanged outside the continent, and the region could save costs by exchanging the content locally.

This Linux tool could improve the security of IoT devices

The first rule of building a secure and feature-rich ecosystem is software management — push and pull software updates and software discovery through an app store mechanism from a trusted source.In the go-to-market IoT race, though, that often doesn’t happen.

Half a dozen clever Linux command line tricks

Working on the Linux command can be a lot of fun, but it can be even more fun when you use commands that take less work on your part or display information in interesting and useful ways. In today’s post, we’re going to look at half a dozen commands that might make your time on the command line more profitable.watch The watch command will repeatedly run whatever command you give it and show you the output. By default, it runs the command every two seconds. Each successive running of the command overwrites what it displayed on the previous run, so you're always looking at the latest data.You might use it when you’re waiting for someone to log in. In this case, you would use the command “watch who” or maybe “watch -n 15 who” to have the command run every 15 seconds instead of every two seconds. The date and time will appear in the upper right-hand corner of your terminal window.To read this article in full or to leave a comment, please click here
