Reliability Engineering Lab

Calculate error budgets, model series or parallel availability, estimate downtime impact, forecast capacity, and coordinate reliability planning in one workspace.

Plan around one service profile

Define a service objective, observed availability, monthly traffic, hourly impact, current load, tested capacity, growth, and component topology. The lab calculates time and request error budgets plus series or parallel system availability.

Make assumptions reviewable

Capacity growth is a bounded compound forecast and component failures are modeled as independent. Save assumptions and findings, then continue into SLO, MTBF/MTTR, recovery, dependency, and business-impact tools. Results inform planning; they do not guarantee uptime.

Frequently Asked Questions

How is an error budget calculated?+

For a time budget, the unavailable fraction is multiplied by the period length. For a request budget, the same fraction is multiplied by request volume and rounded down to a whole failed request.

What is the difference between series and parallel availability?+

In a series model every component must work, so availability values multiply. In a parallel model any component can satisfy the function, so the model subtracts the product of every component failure probability from one.

Is the capacity date a guarantee?+

No. It is a compound-growth forecast from the supplied current load, tested capacity, and monthly growth. Seasonality, architecture changes, queuing, bottlenecks, and planned scaling can materially change the result.
