# Resource Pricing

Kvant resource pricing is based on three independently billed dimensions: compute (CPU), memory (RAM), and persistent storage. Costs are calculated monthly against the requests values defined in each Namespace's ResourceQuota, making billing predictable and directly tied to provisioned capacity rather than variable runtime usage.

# Pricing Reference

Resource	Unit	Price (CHF / month)
Compute (CPU)	1 vCPU core (1000 millicores)	5.50
Memory (RAM)	1 GiB	6.00
Storage	1 GiB	0.03

Over-commitment and billing

Over-commitment is permitted (a Namespace's limits may exceed its requests), but billing is always based on requests. Setting conservative requests and higher limits allows workloads to burst without increasing the base monthly cost.

# Resource Truth Table

The table below defines the behaviour of each resource type across key operational dimensions.

Dimension	Compute (CPU)	Memory (RAM)	Storage
Unit	vCPU (1000m)	GiB	GiB
CHF / unit / month	5.50	6.00	0.03
Compressible	Yes — throttled under contention	No — OOMKill if exceeded	No — fixed allocation
Billing basis	`requests.cpu`	`requests.memory`	`requests.storage`
Quota field	`requests.cpu` / `limits.cpu`	`requests.memory` / `limits.memory`	`requests.storage`
Provisioning mechanism	Kubernetes scheduler	Kubernetes scheduler	PersistentVolumeClaim (PVC)
Excess behaviour	Throttled (no pod eviction)	Pod evicted (OOMKill)	PVC creation blocked
Dynamic scaling	Cluster autoscaler	Cluster autoscaler	StorageClass provisioner
Purchasable capacity (portal)	—	—	100 GiB minimum; 100 GiB steps only

# Per-Resource Pricing Detail

# Compute (CPU)

CPU is measured in vCPU cores, where 1 vCPU = 1000 millicores in Kubernetes notation. CPU is a compressible resource: if a pod attempts to use more than its limit, it is throttled rather than terminated. Billing is based on requests.cpu.

Namespace	CPU Requested	Monthly Cost
dev	2 cores	11.00 CHF
staging	4 cores	22.00 CHF
prod	8 cores	44.00 CHF

# Memory (RAM)

Memory is measured in GiB. Unlike CPU, memory is non-compressible: if a pod exceeds its memory limit, the kernel terminates it with an OOMKill signal. This makes accurate memory requests particularly important for production workloads. Billing is based on requests.memory.

Namespace	RAM Requested	Monthly Cost
dev	4 GiB	24.00 CHF
staging	8 GiB	48.00 CHF
prod	16 GiB	96.00 CHF

# Storage

Persistent storage is provisioned via PersistentVolumeClaims (PVCs) against a configured StorageClass (e.g. Ceph RBD). Storage is billed per GiB at a flat rate and is independent of compute and memory costs, allowing flexible cost modelling for data-heavy workloads.

You buy storage through the portal in 100 GiB increments only: 100 GiB minimum.

PVC size (valid purchases)	Monthly cost
100 GiB	3.00 CHF
200 GiB	6.00 CHF
500 GiB	15.00 CHF
1200 GiB	36.00 CHF

# Example Namespace Cost Calculation

The table below shows a combined monthly cost calculation for a production namespace with typical resource allocations.

Resource	Allocation	Unit Price	Monthly Cost
CPU	8 cores	5.50 CHF	44.00 CHF
Memory	32 GiB	6.00 CHF	192.00 CHF
Storage	500 GiB	0.03 CHF	15.00 CHF
		Total	251.00 CHF
