Cost of Resilience Calculator

An interactive simulator for modeling the trade-offs between uptime targets, architecture choices, downtime cost, and infrastructure spend. This project turns resilience conversations into something measurable instead of abstract.

What It Is

The calculator helps teams reason about resilience as an economic design problem. Instead of talking about availability targets in isolation, it lets you model expected downtime, component topology, replication choices, and the financial trade-offs of building for higher uptime.

Interactive modeling Change assumptions and see the cost/resilience implications immediately.

Architecture-aware Considers component count, replication, and failure behavior instead of abstract SLA math.

Business-grounded Ties uptime decisions back to downtime cost and spend trade-offs.

Decision support Useful for engineering leaders, reliability teams, and FinOps conversations.

Why It Matters

Moves uptime discussions from opinion to model-driven trade-offs.
Helps teams see when marginal resilience improvements stop being economically sensible.
Creates a common language between engineering, reliability, and cost stakeholders.
Fits the broader thread in my work: making operational decisions visible and measurable.

How To Use It

Define the system shape and number of components.
Adjust redundancy and availability assumptions.
Set the business cost of downtime.
Compare the modeled reliability outcome against infrastructure spend.
