NVIDIA’s aggressive purchases could signal the era of open networking

NVIDIA’s plans to acquire Cumulus Networks, a pioneer of using open source for networking, is a sign that open networking is finally ready for a big leap forward.Open networking has been tightly coupled with software-defined networking (SDN) because the combination promises to make networks significantly more agile, open and easier to customize to specific needs. Cumulus has been working on it for years, and NVIDIA started pushing into it when it acquired Mellanox last week.[Get regularly scheduled insights by signing up for Network World newsletters.] The question the Cumulus acquisition raises is “why now”? The concept of open networking has been hotly debated since SDN came into prominence. The concept is sound, and open systems will disrupt the network industry much as it did the compute space. Yet while Linux and open source are wildly successful in the compute industry, open source has yet to take off in networking outside of webscale networks and a handful of large organizations.To read this article in full, please click here

NVIDIA, Mellanox, and Cumulus

Recent press releases, Riding a Cloud: NVIDIA Acquires Network-Software Trailblazer Cumulus and NVIDIA Completes Acquisition of Mellanox, Creating Major Force Driving Next-Gen Data Centers, describe NVIDIA's moves to provide high speed data center networks to connect compute clusters that use of their GPUs to accelerate big data workloads, including: deep learning, climate modeling, animation, data visualization, physics, molecular dynamics etc.

Real-time visibility into compute, network, and GPU infrastructure is required manage and optimize the unified infrastructure. This article explores how the industry standard sFlow technology supported by all three vendors can deliver comprehensive visibility.

Cumulus Linux simplifies operations, providing the same operating system, Linux, that runs on the servers. Cumulus Networks and Mellanox have a long history of working with the Linux community to integrate support for switches. The latest Linux kernels now include native support for network ASICs, seamlessly integrating with standard Linux routing (FRR, Quagga, Bird, etc), configuration (Puppet, Chef, Ansible, etc) and monitoring (collectd, netstat, top, etc) tools.

Linux 4.11 kernel extends packet sampling support describes enhancements to the Linux kernel to support industry standard sFlow instrumentation in network ASICs. Cumulus Linux and Mellanox both support the new Linux APIs. Cumulus Linux uses the open source Continue reading

New 6 GHz Wi-Fi could add $153 billion to U.S. economy: report

Opening the 6 GHz band to Wi-Fi could add $153.75 billion to the U.S. economy over the next five years, according to a new study.In late April, the Federal Communications Commission adopted rules that make 1,200 megahertz of spectrum in the 6 GHz band available for unlicensed use. Freeing up the chunk of 6 GHz spectrum for Wi-Fi is the biggest frequency allocation upgrade to the now aging wireless protocol in 10 years. Wi-Fi using 5 GHz spectrum – the last major touch-up – was introduced in 2009. The original 2.4 GHz Wi-Fi was introduced in 1997.To read this article in full, please click here

How to Build and Test Your Docker Images in the Cloud with Docker Hub

Part 2 in the series on Using Docker Desktop and Docker Hub Together

Introduction

In part 1 of this series, we took a look at installing Docker Desktop, building images, configuring our builds to use build arguments, running our application in containers, and finally, we took a look at how Docker Compose helps in this process. 

In this article, we’ll walk through deploying our code to the cloud, how to use Docker Hub to build our images when we push to GitHub and how to use Docker Hub to automate running tests.

Docker Hub

Docker Hub is the easiest way to create, manage, and ship your team’s images to your cloud environments whether on-premises or into a public cloud.

This first thing you will want to do is create a Docker ID, if you do not already have one, and log in to Hub.

Creating Repositories

Once you’re logged in, let’s create a couple of repos where we will push our images to.

Click on “Repositories” in the main navigation bar and then click the “Create Repository” button at the top of the screen.

You should now see the “Create Repository” screen.

You can create repositories for your Continue reading

Cinco de Mayo – What are we celebrating anyway?

Cinco de Mayo - What are we celebrating anyway?

Greetings from Latinflare, Cloudflare’s LatinX Employee Resource Group, with members all over the US, the UK, and Portugal. Today is Cinco de Mayo! Americans everywhere will be drinking margaritas and eating chips and salsa. But what is this Mexican holiday really about and what exactly are we celebrating?

About Cinco de Mayo

Cinco de Mayo, Spanish for "Fifth of May", is an annual celebration held in Mexico on May 5th. The date is observed to commemorate the Mexican Army's victory over the French Empire at the Battle of Puebla, on May 5, 1862, under the leadership of General Ignacio Zaragoza. The victory of the smaller Mexican force against a larger French force was a boost to morale for the Mexicans. Zaragoza died months after the battle due to illness. A year after the battle, a larger French force defeated the Mexican army at the Second Battle of Puebla, and Mexico City soon fell to the invaders.

Setting up Cloudflare for Teams as a Start-Up Business

Setting up Cloudflare for Teams as a Start-Up Business

Earlier this year, Cloudflare acquired S2 Systems. We were a start-up in Kirkland, Washington and now we are home to Cloudflare’s Seattle-area office.

Our team developed a new approach to remote browser isolation (RBI), a technology that runs your web browser in a cloud data center, stopping threats on the Internet from executing any code on your machine. The closer we can bring that data center to the user, the faster we can make that experience. Since the acquisition, we have been focused on running our RBI platform in every one of Cloudflare’s data centers in 200 cities around the world.

The RBI solution will join a product suite that we call Cloudflare for Teams, which consists of two products: Access and Gateway.

Those two products solve a number of problems that companies have with securing users, devices, and data. As a start-up, we struggled with a few of these challenges in really painful ways:

  • How do we let prospects securely trial our RBI platform?
  • How do we keep our small office secure without an IT staff?
  • How can we connect to the powerful, but physically clunky and heavy development machines, when we are not in that office?

HS. Part 5. Automation at high-scale: Bringing network up (Docker SONIC-P4 and Linux bridges) based on the network graph.

Hello my friend,

Finally we approached the point where we start dealing with the network functions again, now at a high scale. After we have successfully generated the configuration files for our Microsoft Azure SONiC network functions, it is a time to boot them, span them and get the emulated data centre up and running.
