BrandPost: Ethernet Adventures: Making Progress with an Old Friend – Good ol’ Ethernet

In the second post of this 3-part series we unravel one hero’s journey on the road to streamlined enterprise networking operations. Ciena’s Chris Sweetapple follows Our Hero’s adventures as he realizes the opportunities of high-bandwidth business Ethernet.In episode 1 our hero, stuck in a tangle of outdated networking equipment, services and complexity, realizes that with business Ethernet as his WAN technology of choice, he can complement the existing network set-up and connect his branch offices, while handling massive volumes of traffic concurrently using high speed (up to 100G) high-performance Ethernet connectivity.To read this article in full, please click here

Hardware life cycle approaches to save money, ensure network reliability

High-quality, reliable network hardware and data center cabling are requirements for a high-performing technology infrastructure and for a successful IT team that helps drive more business. It’s the life cycle for your network.However, in these days of shrinking budgets and rising demands, CIOs, IT professionals, and buyers are being pressured to do more while reducing costs. How can this be done?Having the right approach when it comes to network hardware and data center cabling is a powerful way to enable your IT organization to do a lot more while optimizing your budget. [ Read also: How to plan a software-defined data-center network ] The IT value within the life cycle There are many nuances to a hardware investment that some organizations don’t take into account.

From Imagination to Action: In Latin America, Building the Internet That Women Want

In 1843, Ada Lovelace published “Sketch of the analytical engine invented by Charles Babbage” in the book Scientific Memoirs. But because of her “condition” as a woman she, like many women who were pioneers in their time, was forgotten by history. Women could not access education or the sciences and, for that reason, history forgot them, just as we forgot that many women were mothers of the Internet.

“History drove us out of the digital industry, we stopped being important and a male industry was created.”
– Kemly Camacho, Sula Batsú

Every day many people ask us, where are the women? Why don’t they participate? I tell them to look at the immense number of initiatives that women are doing in Latin America and the Caribbean.

With the cold of Buenos Aires, between its tall buildings and its warm people, our friends at the Tierra Violeta Cultural Center received us after four months of planning the FemHackParty LAC. In December 2016, at the Internet Governance Forum that took place in Guadalajara, Mexico, we organized with a group of women the first FemHackParty, within the framework of 16 days of activism against violence against women. We had the chance to learn Continue reading

Kubernetes with Cilium and Containerd using Kubeadm

Now, if that isn’t a title jam-packed with buzzwords, I don’t know what is! In seriousness, though, I wanted to share how to use kubeadm to turn up a Kubernetes cluster using containerd (instead of Docker) and Cilium as the CNI plugin. I’m posting this because I wasn’t able to find a reasonable article that combined all the different threads—some posts talked about using containerd, others talked about using Cilium, and the official Kubernetes docs have examples for using kubeadm. The purpose of this post is to try to pull those threads together.

For structure and context, I’ll build upon the official Kubernetes document outlining creating highly available clusters with kubeadm. You may find it helpful to pull up that article next to this one, as I won’t be duplicating that content here. Instead, I’ll just reference additions/changes to the process in order to accommodate containerd and Cilium.

Before getting started, make sure that your systems will meet the minimum requirements for Cilium. For my testing, I used Ubuntu 16.04 with the latest HWE kernel (4.15.0-33-generic). I used a private fork of Wardroom to build the AWS AMIs with containerd and all the Kubernetes 1.11.2 Continue reading

How to pin a pile of addresses onto a Google map

Turning a list of names, addresses and related information into a Google map is a lot easier than you might think. The effort required depends, as you might imagine, on the information that you starting with. But if the format is fairly consistent, it’s relatively easy to massage the information into a form that can be uploaded into a format that works.First, what you can expect Once you’ve loaded a list of names and addresses into a Google map, you will be able view the location of each person and set up your map such that clicking on any of the map markers displays the information collected for that address.To read this article in full, please click here

Last Month In Internet Intelligence: August 2018

During August 2018, the Oracle Internet Intelligence Map surfaced Internet disruptions around the world due to familiar causes including nationwide exams, elections, maintenance, and power outages. A more targeted disruption due to a DDoS attack was also evident, as were a number of issues that may have been related to submarine cable connectivity. In addition, in a bit of good news, the Internet Intelligence Map also provided evidence of two nationwide trials of mobile Internet services in Cuba.

Cuba

On August 15, the Oracle Internet Intelligence Twitter account highlighted that a surge in DNS queries observed the prior day was related to a nationwide test of mobile Internet service, marking the first time that Internet services were available nationwide in Cuba’s history. The figure below shows two marked peaks in DNS query rates from resolvers located in Cuba during the second half of the day (GMT) on the 14th. Paul Calvano, a Web performance architect at Akamai, also observed a roughly 25% increase in their HTTP traffic to Cuba during the trial period.

This testing was reported by ETECSA (the Cuban state telecommunications company) in a Facebook post in which they noted:

The Telecommunications company of Cuba S.A. Continue reading
