Calico is an open-source cloud-native networking and network security platform for Kubernetes, providing pod networking (CNI), network policy enforcement, and observability across multiple data planes including eBPF, standard Linux, Windows, and VPP. It is the most widely adopted container networking solution, supporting BGP routing, VXLAN overlays, WireGuard encryption, and scalable IP address management.
Use cases
- set up pod networking for a kubernetes cluster
- enforce network policies between kubernetes workloads
- encrypt pod traffic with wireguard
- choose a cni plugin for eks gke or aks
- secure outbound egress traffic from pods
- run kubernetes networking on windows nodes
- troubleshoot and observe cluster network traffic
- peer cluster nodes over bgp without an overlay
When to choose
- you need production-grade, widely adopted kubernetes networking with strong network policy support
- you want a choice of data planes including eBPF, iptables, nftables, Windows, or VPP
- you need scalable IPAM, BGP peering, or overlay networking across clouds and bare metal
- you require WireGuard encryption and granular workload access controls
When to avoid
- you need a service mesh or L7 load balancing as the primary feature rather than L3/L4 networking
- you want a fully managed SaaS experience without self-hosting (that requires Calico Cloud)
- your environment is not Kubernetes or OpenStack based
- you need a lightweight single-binary CNI with minimal operational surface
