Announcing the ultimate BGP how-to guide

The Border Gateway Protocol has become the most popular routing protocol in the data center. But for all its popularity, some consider BGP to be too complicated. Despite its maturity and sophistication, many network operators and data center administrators won’t go anywhere near it. If only there were an equally sophisticated BGP guide to solve this problem…

Fortunately, your prayers to the data center gods have been answered. We at Cumulus are incredibly proud of our Chief Scientist, Dinesh Dutt, who has added the title of “published author” to his impressive repertoire with the publication of the ebook BGP in the Data Center. This handy BGP how-to guide, published by O’Reilly Media, is the ideal companion for anyone looking to better understand the Border Gateway Protocol and its place in the data center. It’s perfect for any network operators and engineers that want to become masters of this protocol, regardless of their base level of familiarity with BGP.

In this ebook, Dinesh covers BGP operations and enhancements to simplify its use in order to help readers truly appreciate the elegance and ultimate simplicity of BGP.

This guide covers topics such as:

Moving Forward with Path Forward

Moving Forward with Path Forward

In February, I blogged about our first rotation of Path Forward returnships and the awesome people we’ve hired as a result of the program. As a refresher, Path Forward is a nonprofit organization that aims to empower people who’ve taken time away from their careers to focus on caregiving to return to the workforce.

Cloudflare started partnering with Path Forward this past year as a way to expand our talent pool to include the best and the brightest, regardless of any gaps in their career journeys. We truly believe in a diverse group of employees, and that includes those who can bring different perspectives from their time away from the workforce.

We’ve been lucky to have three amazing candidates go through the Path Forward program this time around across our People & Places, Solutions Engineering, and Marketing teams.

A Look Inside U.S. Nuclear Security’s Commodity Technology Systems

In the following interview, Dr. Matt Leininger, Deputy for Advanced Technology Projects at Lawrence Livermore National Laboratory (LLNL), one of the National Nuclear Security Administration’s (NNSA) Tri Labs describes how scientists at the Tri Labs—LLNL, Los Alamos National Laboratory (LANL), and Sandia National Laboratories (SNL)—carry out the work of certifying America’s nuclear stockpile through computational science and focused above-ground experiments.

We spoke with Dr. Leininger about some of the workflow that Tri Labs scientists follow, how the Commodity Technology Systems clusters are used in their research, and how machine learning is helping them.

The overall goal is to demonstrate a …

Worth Reading: Making mainstream switches malleable

While the hyperscalers of the world are pushing the bandwidth envelope and are rolling out 100 Gb/sec gear in their Ethernet switch fabrics and looking ahead to the not-too-distant future when 200 Gb/sec and even 400 Gb/sec will be available, enterprise customers who make up the majority of switch revenues are still using much slower networks, usually 10 Gb/sec and sometimes even 1 Gb/sec, and 100 Gb/sec seems like a pretty big leap. —Timothy Prickett Morgan @ The Next Platform

DockerCon Europe Diversity Scholarship!

DockerCon Scholarship

Each year, DockerCon brings the community together to learn, belong and contribute. With the support of Docker and our DockerCon Europe Scholarship sponsor, the Open Container Initiative (OCI) our team has created the DockerCon Europe Scholarship Program to provide members of the Docker community, who are traditionally underrepresented, mentorship and a financial scholarship to attend DockerCon in Copenhagen this year. This scholarship program aims to foster inclusivity by supporting members of our community through access to resources, tools and mentorship needed to facilitate career and educational development.


Open Container Initiative

If you are interested in applying for the DockerCon Scholarship, follow the steps below:

Application Process:

The application process includes completing one of the five self-paced trainings along with the scholarship application form.

Step 1

Complete at least one of the free self-paced courses available in the Docker Playground. These courses are intended for both Dev and Ops beginner and intermediate level Docker users. Select which course you feel best fits you.

Step 2

After you’ve finished one of the courses, complete the application here. In the application, you will need to provide the name(s) of the lab(s) you completed along with the answers to the quiz at the end of Continue reading

What is Linux? A powerful component of modern data centers

Linux is a tried-and-true, open source operating system released in 1991 for computers, but its use has expanded to underpin systems for cars, phones, web-servers and, more recently, networking gear.It’s longevity, maturity and security make it one of the most trusted OSes available today, meaning it is ideal for commercial network devices as well as enterprises that want to use it and its peripherals to customize their own network and data center infrastructure.That in turn makes Linux skills highly sought after by IT hiring managers. Many of the new technologies associated with DevOps, for example, such as containers, OpenSource infrastructure and SDN controllers are built on Linux.To read this article in full or to leave a comment, please click here

OSPF Prefix Suppression helps company to use 200 routers

OSPF Prefix Suppression helps to company to use 200 routers in their network without any problem. You can think that, some companies use more than 200 routers in their OSPF network, why this post is special? You will understand why in 10 minutes.   Yes that is true but those companies have either multi-area OSPF […]

Information on the Recent Site Migration

Earlier this week, I completed the migration of this site to an entirely new platform, marking the third or fourth platform migration for this site in its 12-year history. Prior to the migration, the site was generated using Jekyll and GitHub Pages following a previous migration in late 2014. Prior to that, I ran WordPress for about 9 years. So what is it running now?

The site is now generated using Hugo, an extraordinarily fast static site generator. I switched to Hugo because it offers a couple of key benefits over Jekyll:

  1. Site build times are 10x faster (less than 30 seconds with Hugo compared to over 5 minutes with Jekll)—this directly translates into me being able to test changes to the site much more quickly
  2. Hugo is a single binary that’s easily installed on Linux or macOS (and Windows too, though I don’t have any Windows systems)

Hugo also gives me more flexibility that I had with Jekyll, such as generating lists of articles by tag or lists of articles by category. Along with those additions—the ability to browse by tag or category—I’ve also removed the pagination (I mean, who’s really going to page through 188 pages of Continue reading
