What does real resilience actually cost?

Colocation, a disaster-recovery site, and ransomware-resilient immutable backup are three separate line items that almost never get costed together. This calculator builds them up against 2026 retail-colo rates, scores your recovery posture, and shows how the footprint compares to staying all-cloud.

!
Why this exists: after an offensive assessment surfaces a recovery gap, "we have backups" is rarely the same as "we can recover after ransomware." Air-gapped/immutable copies, a warm DR site, and a colo footprint with data-residency control each carry real monthly cost — and procurement usually only sees one of the three. This tool prices the whole resilience stack in one place so the DR conversation starts from a number, not a hope.

Production Footprint

The colocation space you'd run primary workloads in. Cabinet count and power density drive the bill.

Number of full cabinets across your colo footprint.
Power density. 3–5 kW is typical; 10 kW+ is high-density / AI.
Drives the provider shortlist and a power/space premium for EU & multi-region builds.

Disaster Recovery

How hot the second site is. Colder is cheaper but slower to recover.

Warm: standby infra kept current, brought online on failover. ~hours RTO.

Immutable Backup

Air-gapped / immutable copies — the layer that survives ransomware. Priced per TB protected.

Logical data set under immutable protection.
Versioned / retained copies. 2×+ is the minimum for credible immutability.

Colo vs. All-Cloud (Directional)

A planning-grade contrast for the production footprint only. Real comparisons depend on workload shape, commitment discounts, and egress — treat this as a starting point, not a quote.

$0 difference vs colo · 0%
Read this carefully: colocation tends to win on sustained, predictable compute (always-on infra you own), while cloud wins on bursty / elastic workloads you can switch off. The number above assumes 24×7 utilisation. The resilience case for colo is rarely pure cost — it's data residency, sovereign compliance, and an immutable recovery copy that lives outside your primary cloud blast radius.

Monthly Cost as the Footprint Grows

Stacked colo + DR + backup at different cabinet counts. Your current footprint is highlighted.

Planning-grade retail colocation rates for 2026. Wholesale / hyperscale deals price materially lower per kW; high-density and constrained metros (e.g. Northern Virginia, Santa Clara) price higher. Validate against an actual quote before committing.

DR site as % of production

  • Cold (backup/restore): 15% — storage + minimal standby, RTO days
  • Warm (pilot light): 40% — standby infra kept current, RTO hours
  • Hot (active-active): 100% — full duplicate, RTO near-zero

Immutable backup

  • Managed immutable / air-gapped: ~$9 / TB / mo
  • Effective TB = data protected × retention copies

All-cloud contrast

  • Sustained 24×7 cloud-equivalent compute: ~$520 / kW / mo (directional — VM + storage + support for always-on infra)
  • Excludes egress, which the Cloud Egress Estimator covers separately

Not included

  • Network / bandwidth circuits, remote-hands labour, install/NRC one-time fees
  • Hardware capex (servers, storage arrays), licensing, staff
  • DR testing, runbook development, and RPO data-egress during failover
