SUSE’s Rancher acquisition brings containerization support

SUSE’s acquisition of Rancher Labs puts the Germany-based open-source software company in a much stronger position to offer flexible, edge-based services to its customers, according to an analyst at IDC.The deal—which was originally announced this summer—essentially makes Rancher Labs into SUSE’s containerization “innovation center,” said IDC research director Gary Chen. Any customer working on digital transformation and rapid development is likely to appreciate the improved support for containerization—letting workloads function on whatever hardware is handy, and communicate across different arrangements of edge, cloud and local computing.Terms of the deal were not publicly disclosed, but a CNBC report published after the initial announcement quoted sources familiar with the deal as saying that SUSE is paying between $600 million and $700 million.To read this article in full, please click here

Exploring the LEO Satellite Service Landscape for Potential Enterprise Use

What is a WAN? Wide-area network definition and examples

People want to connect to all of their apps all of the time from all of their devices no matter where they are. And they pretty much can, thanks to wide-area networks (WANs).At its core, a WAN is a network of networks. The Internet itself is a giant WAN, and how you connect to it can be as diverse as through an Ethernet cable, coaxial cable, or a cellular radio signal.Your office network, home Wi-Fi, cellphone, smartwatch, doorbell camera and vehicle-based Internet connection are just endpoints on a vast global WAN that is constantly evolving to carry more traffic, and to carrt that traffic faster as the demands for near-instantaneous access to resources increase.To read this article in full, please click here

BGP Training on Ignition

The first hour of material in my new BGP course over at Ignition dropped this week. I’m not going to talk about configuration and other operational things—this is all about understanding how BGP works, why it works that way, and thinking about design. This course will apply to cloud, Internet edge, DC fabric, and other uses of BGP. From the official site:

BGP is one of the fundamental protocols for routing traffic across the Internet. This course, taught by networking expert and network architect Russ White, is designed to take you from BGP basics to understanding BGP at scale. The 6-hour course will be divided into several modules. Each module will contain multiple video courses of approximately 15 minutes each that drill into key concepts. The first module contains four videos that describe how BGP works. They cover basics including reachability, building loop-free paths, BGP convergence, intra-AS models, and route reflectors.

Insights Platform Now Live! A Deeper, Data-Driven View of the Internet

There are many people, projects, and organizations that are collecting data on various facets of the Internet, but there’s no single site that provides a curated set of insights.

To help address this gap, we’ve launched the Internet Society Insights platform to help everyone gain deeper, data-driven insight into the Internet.

One of the key deliverables of the Measuring the Internet project, we have spent the last few months building the Insights platform together with our valued development partner, Frontwerks AG.

Data and Focus Areas

We’re collating data from several trusted organizations – our data partners – and will examine Internet trends, generate reports, and tell data-driven stories about how the Internet is evolving. Insights launched with two initial focus areas, Internet Shutdowns and Enabling Technologies.

Work is continuing on three additional focus areas – Internet Resilience, the Internet Way of Networking, and Keeping Traffic Local. We aim to add data and insights on these focus areas throughout 2021 and beyond.

Use and Share

Everyone is encouraged to use and share the text, images, and charts presented on Insights under our creative commons license.

The Hedge Podcast #62: Jacob Hess and the Importance of History

At first glance, it would seem like the history of a technology would have little to do with teaching that technology. Jacob Hess of NexGenT joins us in this episode of the Hedge to help us understand why he always includes the history of a technology when teaching it—a conversation that broadened out into why learning history is important for all network engineers.

Remembering Francis Kariuki: Africa’s Tweeting Chief

The African community networks community is sad to learn about the passing of one of its prolific members, Chief Francis Kariuki of Lanet-Umoja, a rural community in Nakuru County, Kenya. He died on on 21 October 2020 after a short illness.

Chief Kariuki was a renowned Kenyan administrator who pioneered the use of technology to foster development, justice, trust, peace, and inclusion in his community. His struggle for digital inclusion earned him several nicknames, including “The Digital Champion” and “The Tweeting Chief,” for being the first African local administrator to use social media channels to promote community development. His passion and drive for adopting technologies in service delivery at the local level earned him national and global recognition.

Chief Kariuki was a strong advocate for community networks in Africa. He successfully championed for a community network in Lanet-Umoja and worked with his community members to coordinate its installation, operation, and management.

Beyond Kenya, Chief Kariuki engaged in the Africa Summits on Community Networks, a platform where community network operators in Africa gather to foster learning, networking, knowledge, and experience sharing. At the Summits, Chief Kariuki shared key insights on community networks and inspired many young people to adopt digital Continue reading

KubeCon+CloudNativeCon: Service Mesh Battle Stories and Fixes

KubeCon+CloudNativeCon. “There’s a lot to say about each of these service meshes and how they work: their architecture, why they’re made, what they’re focused on, what they do when they came about and why some of them aren’t here anymore and why we’re still seeing new ones,” Layer5, explained during his talk with “Service Mesh Specifications and Why They Matter in Your Deployment.” Service mesh is increasingly seen as a requirement to manage microservices in Kubernetes environments, offering a central control plane to manage microservices access, testing, metrics and other functionalities. One-third of the respondents in The New Stack survey of our readers said their organizations already use service mesh. Among the numerous service mesh options available; Envoy, Linkerd and

Schneider Electric plans U.S. expansion, announces new micro data centers

Next Pathway launches an automated cloud migration tool

Next Pathway has announced the next-generation of its cloud-migration-planning technology, called Crawler360, which helps enterprises shift legacy data warehouses and data lakes to the cloud by telling them exactly how to cost, size, and start the journey.Data warehouses and especially data lakes can get out of control with poorly managed, siloed data and different forms of structured and unstructured data turning the warehouse and lake into a swamp.Crawler360 addresses this problem by scanning data pipelines, database applications, and business-intelligence tools to automatically capture the end-to-end data lineage of the legacy environment. By doing so, Crawler360 defines relationships across siloed applications to understand their interdependencies, identifies redundant data sets that have swelled over time that can be consolidated, and pinpoints “hot and cold spots” to define which workloads to prioritize for migration.To read this article in full, please click here

Chasing CRC Errors in a Data Center Fabric

One of my readers encountered an interesting problem when upgrading a data center fabric to 100 Gbps leaf-to-spine links:

They installed new fiber cables and SFPs;
Everything looked great… until someone started complaining about application performance problems.
Nothing else has changed, so the culprit must have been the network upgrade.
A closer look at monitoring data revealed CRC errors on every leaf switch. Obviously something was badly wrong with the whole batch of SFPs.

Fortunately my reader took a closer look at the data before they requested a wholesale replacement… and spotted an interesting pattern:
