OpenELA group pushes for bug compatibility with RHEL

A dramatic disagreement in the enterprise Linux community has some distributions scrambling to keep their code compatible with Red Hat, as the acknowledged biggest player in the space cracks down on source code distribution.The core issue is the existence of several “downstream” Linux distributions based on Red Hat Enterprise Linux. Those distributions were historically based on CentOS, a free RHEL clone developed originally for the purposes of testing and development. The downstream distributions in question, however, are supported by companies like CIQ and Oracle – which sell support services for their “clones” of RHEL. This has led to a long-running tension between those companies and Red Hat, whose supporters argue that the downstream companies are simply repackaging Red Hat’s work for profit, while detractors say that Red Hat is violating the sprit – if not, technically, the law – of open source.To read this article in full, please click here

BGP Labs: The Basics

The first BGP labs are online. They cover the basic stuff (one has to start with the basics, right?):

• Configuring an EBGP session
• Connecting to multiple upstream ISPs
• Advertise your prefixes
• Configure BGP for IPv6

The labs are supposed to be run on virtual devices, but if you’re stubborn enough it’s possible to make them work with the physical gear. In theory, you could use any system you like to set up the virtual lab (including GNS3 and CML/VIRL), but your life will be way easier if you use netlab – it supports BGP on almost 20 different devices. For more details, read the Installation and Setup documentation.

Ansible Community Day, Berlin 2023

Ansible Community Day, Berlin 2023

The Ansible Community Day is a new initiative by the Ansible Community Team at Red Hat to connect with the people using, contributing to, and developing the Ansible project worldwide. This new event complements the Ansible Contributor Summit, to put the users of Ansible in all their shapes and forms front and center.

In the last Ansible Community Day in Boston, the day right before AnsibleFest 2023, the community had the opportunity to meet in-person and get to know each other, learn a few things and share their knowledge using Ansible. It was such a great experience that we couldn't wait to have another. And here it is!

Guten Tag Berlin!

After two very successful Ansible Community Day events this year, the first in Pune, India in February and the next in Boston in May, our third event for 2023 will be held in Berlin, Germany!

Registration for Ansible Community Day Berlin 2023 is now open! If you'd like to attend, please check out the following Eventbrite page for specific details and registration. 

The event is set for Wednesday, September 20, 2023. We will meet in c-base (Rungestraße 20, Berlin, Germany)

How to Make SD-WAN Predictive Automation a Reality

Introducing the 2023 Intern-ets!

This year, Cloudflare welcomed a class of approximately 40 interns, hailing from five different countries for an unforgettable summer. As we joined both remotely and in-person across Cloudflare’s global offices, our experiences spanned a variety of roles from engineering, product management to internal auditing and marketing. Through invaluable mentorship, continuous learning, and the chance to make a real-world impact, our summer was truly enriched at every step. Join us, Anni and Emilie, as we provide an insider's perspective on a summer at Cloudflare, sharing snippets and quotes from our intern cohort.

printf(“Hello Intern-ets!”)

You might have noticed that we have a new name for the interns: the Intern-ets! Our fresh intern nickname was born from a brainstorm between us and our recruiter, Judy. While “Cloudies”, “Cloudterns”, and “Flaries” made the shortlist, a company-wide vote crowned "Intern-ets" as the favorite. And just like that, we've made Cloudflare history!

git commit -m “Innovation!”

We're all incredibly proud to have gotten the opportunity to tackle interesting and highly impactful projects throughout the duration of our internships. To give you a glimpse of our summer, here are a few that showcase the breadth and depth of our experiences.

BrandPost: What do music and multi-cloud networking (MCN) have in common?

By: Nav Chander, Head of Service Provider SD-WAN/SASE Product Marketing at HPE Aruba Networking.In this first of a three-part blog series on SD-WAN, SSE, and multi-cloud networking (MCN), where we will highlight how these three technology areas are analogous to three different musical instruments that can be played separately. However, when these three technologies are “synchronized,” much like a musical ensemble of the three instruments blends the music to create a perfect harmony and an enjoyable listening experience.To read this article in full, please click here

Generating Network Diagrams from Netbox with Pynetbox

Here’s my typical disclaimer: I’m not a developer. I have the ability to make code give me an expected output, but I do not do anything “the right way.”

All the code I write for these blog posts is in my Github repo that you can and should freely copy and modify. Here’s the environment I’m running this stuff in. Python. Pynetbox. You know the drill by now.

Python         :  3.9.10
Pynetbox       :  7.0.0
Netbox version :  3.5.8

We’ve been working through some stuff, and, at this point, we have a lot of stuff in our Netbox instance. Let’s step up the game a little, though, and see if we can’t generate a network diagram based on that data. Let’s set some expectations, though. This is not going to be comparable to that Visio diagram you’ve managed by hand for the last 8 years. This is going to be a very simple diagram with subnet, nodes, and IP addresses — enough for an auditor or for some architect who doesn’t know what’s in their own data centers.

The logic is pretty easy. The first thing we do it query for all our prefixes. Continue reading

New report: The state of Calico Open Source 2023

We are excited to announce the publication of our 2023 State of Calico Open Source, Usage & Adoption report! The report compiles survey results from more than 1,200 Calico Open Source users from around the world, who are actively using Calico in their container and Kubernetes environments. It sheds light on how they are using Calico across various environments, while also highlighting different aspects of Calico’s adoption in terms of platforms, data planes, and policies.

Report highlights

The report shows that Calico continues to be a pivotal part of the container and Kubernetes ecosystem, finding large-scale adoption across major Kubernetes platforms.

• Calico Open Source is mainly used for Kubernetes networking and security
  • 63% are using Calico as a security policy engine on top of an existing CNI
• The top 3 Calico capabilities driving user adoption are its scalable networking, security policies and interoperability across different environments
• Calico users are using a combination of data planes including eBPF, standard Linux and Windows
  • 16% of respondents use Calico’s newer eBPF data plane
• Calico policy creation and deployment is driven by the need for workload access control and secure egress access
  • 85% of users need to achieve network segmentation and protect east-west traffic

Beyond OSI: The ‘Four Things’ Model Of Networking

How GitHub Learned How Hard Distributed Systems Are

Anne Baretta found a great video describing the October 2018 GitHub failure. Here’s the TL&DW:

• The failure was caused by a short (~ 1 minute) disconnect of the primary data center
• The database replicas failed over to the secondary data center, but that failover was never tested and of course some stuff didn’t work.
• In the meantime, batch jobs modified data in the primary data center, making the two replicas out-of-sync.
• It took them over 24 hours to clean up the mess.

Networking vendors highlight AI opportunities as order backlog challenges begin to subside

The heavy buzz around all things AI got louder in the financial reports of networking vendors this quarter, even though AI hasn’t made a significant impact on most vendors’ financial performance and supply chain challenges remain a more immediate concern.Vendors such as Cisco, Arista, Juniper, Extreme and HPE’s Aruba report that they are shipping more products, thanks to multi-month efforts that include significant product redesigns and relentless efforts by their supply-chain teams to address component shortages. But the situation is still challenging, and some enterprise customers still face order delays.To read this article in full, please click here
