Our review
Pros
  • eBPF-based networking with Layer 3 through Layer 7 policies
  • Hubble provides network and security observability
  • Integrates with Kubernetes, Docker, Helm, Prometheus, and Grafana
  • Supports overlay, underlay, VLAN, VPC, NAT, and load balancing
  • Adds policy enforcement, QoS, traffic mirroring, and BGP routing
  • Provides KubeVirt networking and live migration support
Cons
  • Focused on Linux container platforms such as Kubernetes and Docker
  • Its broad feature set spans networking, security, APIs, and observability
  • Self-hosted and hybrid deployments require platform-level ownership
  • Deployment is limited to Linux and self-hosted environments
  • Requires teams to operate the Kubernetes networking components themselves
  • Its broad feature set may exceed the needs of simple cluster networking
