Tigera’s eBPF‑based Calico simplifies VM migration to Kubernetes by removing network reconfiguration needs
Executive summary: Tigera launched Calico based on eBPF for virtual machines running on Kubernetes, enabling VM migration without network reconfiguration. The product gives VMware‑migrating enterprises a NSX‑alternative that simplifies network automation and reduces operational complexity in Kubernetes environments.
Who is involved: Tigera (vendor), Kubernetes platform, enterprises using VMware, and potentially NSX users.
Likely next: Adoption of eBPF‑driven networking is expected to grow, with Tigera likely pursuing integrations with major cloud providers and further feature enhancements.
On July 24 2026, Tigera announced a new version of its Calico networking solution that runs on the eBPF data plane and is designed specifically for virtual machines operating on Kubernetes clusters. The release targets enterprises migrating workloads from VMware environments, promising that VMs can be moved without altering existing network configurations, thereby offering an alternative to VMware’s NSX. By leveraging eBPF, Tigera aims to reduce operational overhead and improve performance for hybrid container‑VM infrastructures.
