What’s New in Calico: Winter 2025

As we kick off the new year, we’re excited to introduce the latest updates to Calico, designed to create a single, unified platform for all your Kubernetes networking, security, and observability needs. These new features help organizations reduce tool sprawl, streamline operations, and lower costs, making it more convenient and efficient to manage Kubernetes environments.

In this blog, we’ll highlight some of the most exciting additions that include a major new product capability, an ingress gateway.

Introducing the Calico Ingress Gateway

Managing and securing traffic in Kubernetes environments is one of the most complex and critical challenges organizations face today. With more than 60% of enterprises having adopted Kubernetes, according to an annual CNCF survey, controlling and optimizing how external traffic enters clusters is more important than ever. As applications grow in scale and complexity, legacy ingress solutions often fall short, plagued by operational inefficiencies, reliance on proprietary APIs, limited scalability, and difficulty in customization. These limitations make it difficult for teams to maintain consistent performance and robust security across their environments.

To address these challenges, we’re excited to introduce the Calico Ingress Gateway, an enterprise hardened, 100% upstream distribution of Envoy Gateway that leverages and expands the Continue reading

Automatic Audit Logs: new updates deliver increased transparency and accountability

What are audit logs and why do they matter?

Audit logs are a critical tool for tracking and recording changes, actions, and resource access patterns within your Cloudflare environment. They provide visibility into who performed an action, what the action was, when it occurred, where it happened, and how it was executed. This enables security teams to identify vulnerabilities, ensure regulatory compliance, and assist in troubleshooting operational issues. Audit logs provide critical transparency and accountability. That's why we're making them "automatic" — eliminating the need for individual Cloudflare product teams to manually send events. Instead, audit logs are generated automatically in a standardized format when an action is performed, providing complete visibility and ensuring comprehensive coverage across all our products.

What's new?

We're excited to announce the beta release of Automatic Audit Logs — a system that unifies audit logging across Cloudflare products. This new system is designed to give you a complete and consistent view of your environment’s activity. Here’s how we’ve enhanced our audit logging capabilities:

  • Standardized logging: Previously, audit logs generation was dependent on separate internal teams, which could lead to gaps and inconsistencies. Now, audit logs are automatically produced in a seamless and standardized way, eliminating Continue reading

Projects to Work On – the AI Recommendations

Cisco Is The Bellwether Of Enterprise AI Adoption

While the hyperscalers and big cloud builders all are racing as fast as they can to build the biggest – and presumably the best – models, or collections of models, to win the AI race and become the Microsoft or Red Hat of commercial-grade models, the acquisition of AI hardware and envelope pushing on AI model architecture is not indicative of the adoption of AI by enterprises. …

HPE Sets Gen12 ProLiant Servers Loose On AI And The Edge

Hewlett Packard Enterprise last summer introduced the first of its Gen12 ProLiant systems, packed with Nvidia’s latest GPU accelerators and aimed squarely at the rapidly expanding AI space that in less than two years went from prompt-and-respond chatbots to AI agents that can reason, plan, and collaborate on their own. …

Point-to-Point Links in Virtual Labs

In the previous blog post, I described the usual mechanisms used to connect virtual machines or containers in a virtual lab, and the drawbacks of using Linux bridges to connect virtual network devices.

In this blog post, we’ll see how KVM/QEMU/libvirt/Vagrant use UDP tunnels to connect virtual machines, and how containerlab creates point-to-point vEth links between Linux containers.

Offline celebrations: how Christmas, NYE, and Lunar New Year festivities shape online behavior

Now that 2025 has been here for a few weeks and 2024 has closed with a variety of year-end traditions — from Christmas and Hanukkah celebrations to New Year’s Eve (NYE) countdowns, as well as celebrations of Orthodox Christmas, and Lunar/Chinese New Year — let’s examine how these events have shaped online behavior across continents and cultures. Reflecting on Christmas and NYE 2024 provides insights into how these trends compared with those of the previous year, as detailed in an earlier blog.

One notable finding is the remarkable consistency in human online patterns from one year to the next, a trend that persists despite cultural differences among countries. Data from over 50 countries reveal how people celebrated in 2024–2025, offering a timely reminder of typical holiday trends. While Christmas remains a dominant influence in many regions, other cultural and religious events — such as Hanukkah and local festivities — also shape online habits where Western traditions hold less sway.

In regions where Christmas is deeply rooted, Internet traffic dips significantly during Christmas Eve dinners, midnight masses, morning gift exchanges, and Christmas Day lunches, a pattern evident in both our previous and current analyses.

This analysis focuses exclusively on non-bot Internet Continue reading

Tagged VLAN 1 In a Trunk Is a Really Bad Idea

It all started with a netlab issue describing different interpretations of VLAN 1 in a trunk. While Cumulus NVUE (the way the netlab configuration template configures it) assumes that the VLAN 1 in a trunk is tagged, Arista EOS assumes it’s the native VLAN.

At that point, I should have said, “that’s crazy, we shouldn’t allow that” and enforce the “VLAN 1 has to be used as a native VLAN” rule. Alas, 20/20 hindsight never helped anyone.

TL&DR: Do not use VLAN 1 in VLAN trunks; if you have to, use it as a native VLAN.
