How many times have you heard you should “shift left” in the last few years? What does “shift left” even mean? Even if it had meaning once, does it still have any meaning today? Should we abandon the concept, or just the term? Listen in as Chris Romeo joins Tom Ammon and Russ White to talk about the origin, meaning, and modern uselessness of the term “shift left.”

We don’t like a mystery and we particularly don’t like it when what is very likely the most powerful supercomputer in the world – at this time anyway – is veiled in secrecy. …

Welcome to Technology Short Take #174! For your reading pleasure, I’ve collected links on topics ranging from Kubernetes Gateway API to recent AWS attack techniques to some geeky Linux and Git topics. There’s something here for most everyone, I’d say! But enough of my rambling, let’s get on to the good stuff. Enjoy!
I just finished spending a wonderful week at Cisco Live EMEA and getting to catch up with some of the best people in the industry. I got to chat with trainers like Orhan Ergun and David Bombal and see how they’re continuing to embrace the need for people in the networking community to gain knowledge and training. It also made me think about a concept I recently heard about that turns out to be a perfect analogy to my training philosophy even though it’s almost 70 years old.
Repetition without repetition. The idea seems like a tautology at first. How can I repeat something without repeating it. I’m sure that the people in 1967 that picked up the book by Soviet neurophysiologist Nikolai Aleksandrovitsch Bernstein were just as confused. Why should you do things over and over again if not to get good at performing the task or learning the skill?
The key in this research from Bernstein lay in how the practice happens. In this particular case he looked at blacksmiths to see how they used hammers to strike the pieces they were working on. The most accurate of his test subjects didn’t just perform the Continue reading

It is no secret that Cloudflare is encouraging companies to deprecate their use of IPv4 addresses and move to IPv6 addresses. We have a couple articles on the subject from this year:
And many more in our catalog. To help with this, we spent time this last year investigating and implementing infrastructure to reduce our internal and egress use of IPv4 addresses. We prefer to re-allocate our addresses than to purchase more due to increasing costs. And in this effort we discovered that our cache service is one of our bigger consumers of IPv4 addresses. Before we remove IPv4 addresses for our cache services, we first need to understand how cache works at Cloudflare.
Describing the full scope of the architecture is out of scope of this article, however, we can provide a basic outline:
For a market that is so integral to the global economy, it sure is hard to get a complete dataset on quarterly and annual spending on information technology. …

We are excited to announce CalicoCon 2024, an in-person learning event for Project Calico, taking place March 19th, 2024 as a co-located event with KubeCon + CloudNativeCon Europe 2024.
As Kubernetes continues to expand its presence in both enterprises and small-to-medium businesses, understanding container networking and security in managed or self-managed Kubernetes environments becomes crucial. Organizations are now presented with choices for dataplanes, such as eBPF, Windows HNS, and Linux IP tables, multi-cloud and Kubernetes distributions as they scale their applications and make them more performance-efficient. Additionally, the process of creating new cloud-native applications or modernizing legacy applications also presents Kubernetes users with a selection of cutting-edge and mature container networking and security technologies.
To make these decisions to leverage their existing investments and future-proofing, users require guidance on developing and implementing scalable network security policies, selecting dataplanes, achieving low latency, optimizing resources, and integrating with bare metal and VM workloads.
At CalicoCon, we will provide KubeCon Paris 2024 attendees with an opportunity to actively participate in a full-day event where they will:
As more organizations collectively progress toward adopting a SASE architecture, it has become clear that the traditional SASE market definition (SSE + SD-WAN) is not enough. It forces some teams to work with multiple vendors to address their specific needs, introducing performance and security tradeoffs. More worrisome, it draws focus more to a checklist of services than a vendor’s underlying architecture. Even the most advanced individual security services or traffic on-ramps don’t matter if organizations ultimately send their traffic through a fragmented, flawed network.
Single-vendor SASE is a critical trend to converge disparate security and networking technologies, yet enterprise "any-to-any connectivity" needs true network modernization for SASE to work for all teams. Over the past few years, Cloudflare has launched capabilities to help organizations modernize their networks as they navigate their short- and long-term roadmaps of SASE use cases. We’ve helped simplify SASE implementation, regardless of the team leading the initiative.
Today, we are announcing a series of updates to our SASE platform, Cloudflare One, that further the promise of a single-vendor SASE architecture. Through these new capabilities, Cloudflare makes SASE networking more flexible and accessible for Continue reading
One of the few beauties of most “industry standard CLI” implementations1 is that they’re idempotent: nothing changes (apart from ACLs) if you configure the same stuff a dozen times. Most of these implementations allow you to deconfigure the same stuff multiple times; FRRouting is one of the unfortunate exceptions.
Imagine you have a bunch of IP prefixes you want to advertise with BGP. You could use network statements within the router bgp configuration to get that done:
