CalicoCon 2025 What’s New in Calico v3.30 Enhanced Observability with Whisker Migrating to nftables and Calico eBPF Calico APIs and Integration AMA with Calico Engineers Party with Calico Cool Cats KubeCon Impressions In Summary When I got the assignment to attend KubeCon 1st of April I thought it was an April prank, but as the date got closer I realized—this is for real and I’ll be on the ground in London at the tenth anniversary of cloud native computing. I’ve seen a lot of tech events during my years in the industry while trying not to get replaced by AI and I have to say this one stands out! Image source: CNCF YouTube Channel Here is my recap of KubeCon + CloudNativeCon Europe 2025. CalicoCon is an event that happens twice every year, as a co-located event during KubeCon NA and EU. It’s a free event that allows you to learn about Tigera’s vision for the future of networking and security in the cloud. There’s also an after-party to celebrate our community and people like you who are on this journey with us! This year our main focus was on Calico v3.30 , our upcoming release that will add a lot of anticipated features to Calico, unlocking things like observability, staged network policy, and gateway api. CalicoCon brought together cloud-native enthusiasts to explore the latest advancements in Calico and Kubernetes networking. The following is a brief summary of this year’s CalicoCon sessions. Note: The CalicoCon playlist with session recordings is now available on YouTube. Peter Kelly, VP of Engineering at Tigera, highlighted the new features in Calico v3.30. A key focus was on the new observability features, including the “Whisker” dashboard, designed to provide deeper insights into network behavior. Reza, our developer advocate at TIgera, led a session dedicated to the new observability features in Calico Open Source v3.30, centered around the Whisker dashboard. The session emphasized the importance of network observability in dynamic Kubernetes environments and included a hands-on demo.
