What's New in Calico v3.32

We’re excited to announce the release of Calico Open Source v3.32! This release corresponds with Kubernetes v1.36 (Codename Haru) and it goes beyond just sharing a cat as the mascot of the release, it actually extends capabilities and features of Kubernetes to keep you up to date with the latest innovations of the cloud. This release brings some of the most significant architectural changes in Calico, from live-migrating KubeVirt VMs to eBPF based Maglev load balancer.

Calculating The Kubernetes Integration Tax: What Your DIY Networking Stack Actually Costs

It was 11:47pm on a Thursday night, and a senior platform engineer at a large North American bank was rolling back a ‘simple’ configuration change. The change itself was small, a routine update approved through the usual review process, but when it was applied, pods began cycling and connections started dropping. For the next three seconds, mobile banking sessions already mid-transaction dropped. Customer support lit up.

VM Migration to Kubernetes: What Breaks and How to Prevent It

Here is what nobody putting together the business case for a VM migration to Kubernetes will tell you upfront: the compute is the easy part. Moving workloads off vSphere and onto Kubernetes is conceptually straightforward. The tooling has matured. The architecture is proven. Compute moves, storage remaps, and the platform team has a plan. The network is where projects quietly stall.

KubeVirt Networking: How to Preserve VM IP Addresses During Migration

Organisations are re-evaluating their VM infrastructure. The economics have shifted, the tooling has matured, and the case for running two separate platforms, one for containers, one for VMs, is getting harder to justify. Platform teams that spent years managing hypervisor infrastructure are being asked to consolidate, and most are landing on the same answer: Kubernetes. KubeVirt makes running VMs on Kubernetes possible.

Your AI Agents Are Autonomous. But Are They Accountable?

Why accountability, not capability, is the real bottleneck for enterprise agentic AI, and what security leaders need to do about it before regulators force the issue. Every enterprise is building AI agents. Marketing has one summarizing campaign performance. Engineering has one triaging incidents. Customer support has one resolving tickets. Finance has one processing invoices.

Deployed Is Not the Same as Ready: How Mature Is Your Kubernetes Environment?

Kubernetes adoption is no longer the challenge it once was. More than 82% of enterprises run containers in production, most of them on multiple Kubernetes clusters. Adoption, however, does not mean operational maturity. These are two very different things. It is one thing to deploy workloads to a cluster or two and quite another to do it securely, efficiently and at scale. This distinction matters because the gap between adoption and Kubernetes operational maturity is where risk accumulates.

Beyond the Prompt: AI Agent Design Patterns and the New Governance Gap

If you are treating Large Language Models (LLMs) like simple question-and-answer machines, you are leaving their most transformative potential on the table. The industry has officially shifted from zero-shot prompting to structured AI agent design patterns and agentic workflows where AI iteratively reasons, uses external tools, and collaborates to solve complex engineering problems.

Introducing Calico Load Balancer and Seamless VM-to-Kubernetes Migration

SAN JOSE, Calif., March 23, 2026 — Tigera, the creator and maintainer of Project Calico, today announced a major expansion of its Unified Network Security Platform for Kubernetes, aimed at helping enterprises consolidate infrastructure and accelerate the migration of legacy workloads to cloud-native platforms.

Secure and Scale VMware VKS with Calico Kubernetes Networking

VMware vSphere Kubernetes Service (VKS) is the CNCF-certified Kubernetes runtime built directly into VMware Cloud Foundation (VCF), which delivers a single platform for both virtual machines and containers. VKS enables platform engineers to deploy, manage, and scale Kubernetes clusters while leveraging a comprehensive set of cloud services. And with VKS v3.6, that foundation just got significantly more powerful.

Calico Load Balancer: Simplifying Network Traffic Management with eBPF

Ever had a load balancer become the bottleneck in an on-prem Kubernetes cluster? You are not alone. Traditional hardware load balancers add cost, create coordination overhead, and can make scaling painful. A Kubernetes-native approach can overcome many of those challenges by pushing load balancing into the cluster data plane.
