Error Budget Calculator
Calculate the tolerable downtime of your service.
Error Budgets are a framework for managing risk and bringing balance between development and SREs. In particular, they are basically used to measure how much risk we are willing to tolerate in a service. As long as the measured uptime/availability is above the SLA/SLO, there is an error budget remaining. Consequently, new features and releases can be pushed to production.
To calculate how much downtime should be permitted in your SLA or SLO, check the Availability Calculator.
