Infrastructure Calculators

Calculate the monthly cost of running a Kubernetes cluster on Hetzner Cloud. Choose server types for control planes, workers, and load balancers with HA mode.

Calculate the right number and size of Kubernetes worker nodes for your workloads. Supports Hetzner Cloud and Vultr with verified pricing.

Calculate RAM and CPU requirements for a k3s cluster. k3s has 5–10× lower overhead than full Kubernetes — see exactly how much your server and agent nodes need.

Calculate when your Kubernetes certificates expire and whether you need to renew them. kubeadm certificates are valid for 1 year — missing renewal breaks the cluster.

Estimate the size of etcd snapshots and monthly backup storage for your Kubernetes cluster. Plan S3 storage costs for etcd backup retention.

Plan your Kubernetes upgrade path from any version to any version. Kubernetes only allows upgrading one minor version at a time — calculate the number of hops and total time estimate.

Calculate the right HPA (Horizontal Pod Autoscaler) CPU and memory thresholds for your Kubernetes workloads. Get absolute target values in millicores and MiB.

Calculate Kubernetes resource requirements for a self-hosted Temporal workflow engine. Size the History, Matching, Frontend, and Worker services plus the PostgreSQL persistence layer.

Calculate the monthly cost of running a Kubernetes cluster on DigitalOcean Managed Kubernetes (DOKS). Control plane is free — you only pay for worker nodes.

Calculate the monthly cost of running a Kubernetes cluster on OVH Managed Kubernetes. Control plane is free — you pay only for worker node instances in EU regions.

Convert SLA percentages to real downtime. See exactly how many minutes of downtime 99.9%, 99.95%, and 99.99% actually allow per year, month, week, and day.

Calculate how much memory your Redis deployment needs on Kubernetes. Accounts for dataset size, replication, overhead, and Redis Cluster mode.

Calculate the right CPU and memory for your PostgreSQL pods on Kubernetes. Based on database size, connection count, and workload type — with postgresql.conf recommendations.

Calculate namespace ResourceQuota values for your Kubernetes cluster. Set CPU and memory limits per namespace based on team size, pod count, and a safety buffer.

Calculate the total storage required for Longhorn distributed block storage, including replica overhead, snapshot retention, and S3 backup sizing on Hetzner Object Storage.

Calculate the GPU VRAM required to run any LLM locally or on cloud GPU. Supports all quantization levels — FP32, FP16, INT8, INT4, and GGUF variants.

Compare GPU cloud rental costs across RunPod, Lambda Labs, and Vast.ai. Calculate monthly spend for LLM inference, fine-tuning, and ML training workloads.

Size your Prometheus, Grafana, Loki, and Alertmanager stack. Calculate RAM, disk, and CPU requirements based on your cluster size and retention period.

Calculate Prometheus disk and RAM requirements based on active time series count, scrape interval, and retention period. Includes TSDB head, WAL, and chunk cache sizing.

Calculate Grafana Loki disk, S3 storage, and RAM requirements based on pod count, log rate, compression ratio, and retention period.

Calculate Grafana RAM, CPU, and storage requirements based on dashboard count, concurrent users, alert rules, and data source count.

Calculate Grafana Tempo or Jaeger distributed tracing storage requirements. Size disk, S3, and RAM based on spans/sec, bytes per span, sampling rate, and retention.

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.

Calculate Cilium CNI agent RAM and CPU requirements per node. Includes Hubble observability overhead, WireGuard encryption, and BPF map memory for network policies.

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.
