I created a netlab topology you can use to practice BGP security tools I described in the Internet Routing Security webinar:
What we consider ‘fast’ is changing. In just over a century we’ve cut the time taken to travel to the other side of the world from 28 days to 17 hours. We developed a vaccine for a virus causing a global pandemic in just one year - 10% of the typical time. AI has reduced the time taken to complete software development tasks by 55%. As a society, we are driven by metrics - and the need to beat what existed before.
At Cloudflare we don't focus on metrics of days gone by. We’re not aiming for “faster horses”. Instead we are driven by questions such as “What does it actually look like for users?”, “How is this actually speeding up the Internet?”, and “How does this make the customer faster?”.
This innovation week we are helping users measure what matters. We will cover a range of topics including how we are fastest at Zero Trust, have the fastest network and a deep dive on cache purge and why global purge latency mightn’t be the gold star it's made out to be. We’ll also cover why Time to First Byte is generally a bad measurement. And what Continue reading

June 27th marks the seventh anniversary of NetBox, a one-time hobby project which quickly took off and today largely consumes my life. What began as a proof-of-concept solution for the network engineering team at DigitalOcean is now perhaps the most widely deployed network source of truth in the world.
This feels like an opportune time to reflect on some lessons I've learned along the way, with the hope of offering mixed encouragement and caution to those considering a similar path. And as I've felt the urge to pick up blogging again, this post will also serve to share what I've been up to recently.
Most articles about open source in general are boring. Reading about licenses and software governance feels like a punishment. Keenly aware of this fact, I'll do my best to navigate around the theory and stick with observations that are of practical use to the aspiring open source maintainer.

Today we’re going deep on software-defined networking for containers and OpenStack with sponsor Juniper Networks. Juniper has revamped its approach to secure networking for telcos and telco cloud-delivered services with Juniper’s Cloud-Native Contrail Networking or CN2 software. CN2 lets you automate the creation of network connections for containers and for virtual machines while also providing routing, security, segmentation and isolation of workloads. Our guest and guide into the guts of Cloud-Native Contrail Networking, hereafter referred to as CN2, is Nick Davey. Nick is Director of Product Management for SDN and Telco Cloud technologies.

The expanded lineup of AMD’s 4th generation “Genoa” Epyc server chips – built atop “Zen 4” core and some with the chip maker’s L3-boosting 3D V-Cache – unveiled at a high-profile event in San Francisco this week is quickly making its way into the cloud. …

The Internet has become very centralized in the last five to ten years, causing a lot of concern among among many in the Internet community. While we cannot turn back the clock, we can try to chart a path forward to reduce the tendency towards centralization. Join Dirk Dirk Kutscher, Lixia Zhang, Alvaro Retana, Tom Ammon, and Russ White on this episode of the Hedge as we discuss the work the Distributed Internet Research Group (DINRG) is doing to create a more decentralized Internet.
In this episode of the Kubernetes Unpacked podcast, co-hosts Michael Levan and Kristina Devochko interview David Flanagan, a Kubernetes consultant, about his experience running his own consultancy and specializing in a specific technology or platform. David shares his career journey and emphasizes the importance of authenticity, credibility, and long-term thinking in the world of technology consulting. The conversation also touches on the use of AI in Kubernetes, the challenges and rewards of being an independent consultant, and the importance of setting personal boundaries and constraints early on to prevent burnout. David also shares his insights into some of the quirks of Kubernetes.

Established in 1875, HanseMerkur is one of the oldest private health insurance companies in Germany, with customers across Europe. The company ran multi-tenant clusters on premises with Kubespray, with around 150 internal software developers as users. As the company must handle personal information and confidential data, it adheres to ISO 27001, the German equivalent of SOC 2, as per industry standards.
The company’s legacy platform was based on Kubernetes 1.11 (released in 2018), and no updates could be made without completely rebuilding the platform. In fact, the company needed to build new clusters for each new product and also rebuild the existing clusters in order to update Kubernetes versions.
HanseMerkur’s clusters were virtualized on top of a legacy hypervisor, and resources had to be sized for traditional deployment on a per tenant basis. There were a number of issues with this set up, including high overhead, low flexibility, and over-consumption of hardware. As a result, the company’s platform team wanted to go bare metal and consolidate the company’s entire infrastructure into one place.
In an exclusive interview, HanseMerkur details how Calico helped solve the challenges of their consolidation project and helped the company enforce the security and observability capabilities Continue reading
