Networking Calculators
Ingress controller comparisons, load balancer configurations, and bandwidth estimators.
Service Mesh Overhead Calculator
Calculate the RAM, CPU, and latency overhead of running Istio, Linkerd, or Cilium as a service mesh. Compare sidecar vs eBPF approaches per pod and cluster-wide.
Cilium Resource Requirements Calculator
Calculate Cilium CNI agent RAM and CPU requirements per node. Includes Hubble observability overhead, WireGuard encryption, and BPF map memory for network policies.
Kubernetes Bandwidth Estimator
Estimate internal pod-to-pod bandwidth, external egress, and recommended NIC size for your Kubernetes cluster. Accounts for service mesh overhead and Hetzner egress pricing.
