What’s Your Approach to Digital Transformation?
As you go through digital transformation, there are a few things to keep in mind. Here are some steps to consider for digital transformation that allows flexibility for future growth.
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
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
eBay Moves Away From OpenStack, Embraces Kubernetes and Docker

Getting Started: Visit Us at AnsibleFest!
Hello, and welcome to another Getting Started blog post… though this one is a bit different. I’d like to tell you about AnsibleFest 2018 in Austin, TX, where for the first time there will be a dedicated Getting Started section at this annual event!
Participants who visit our area will be able to meet some members of the Getting Started team as well as attend presentations. The scheduled talks include Ansible Essentials (similar to the monthly webinars) and Writing Your First Playbook, based on our most popular blog post.
In addition to the two scheduled talks each day, there will also be a lounge area where attendees can ask questions and get answers from Ansible experts in person! Come stop by to learn about what makes Ansible different, how it works, and get a quick overview of Ansible Tower. No experience is required, which means this is going to be a great chance for you or perhaps a teammate who is new to Ansible to learn about it from the ground up.
Make sure to register soon so that we can see you in Austin this October!
Using DevOps to Simplify Disaster Recovery
Disaster recovery plans are quickly outdated in today’s changing environments. One way to keep DR plans updated and tested is to incorporate DevOps practices.
Valley-Free Routing
Reading academic articles about Internet-wide routing challenges you might stumble upon valley-free routing – a pretty important concept with applications in WAN and data center routing design.
If you’re interested in the academic discussions, you’ll find a pretty exhaustive list of papers on this topic in the Informative References section of RFC 7908; here’s the over-simplified version.

Mode briefed Ethan Banks about their cloud private network. Whoa! Thought Mode was an SD-WAN company? Not quite. Mode partners with several SD-WAN platforms so that it's easy to stand up a tunnel from your SD-WAN forwarders to Mode's private network. That makes Mode a network alternative to private MPLS that integrates with your SD-WAN fabric.
