Error budgets are a critical tool for managing system downtime, balancing planned maintenance and unexpected outages to meet service-level objectives (SLOs). They are calculated using projected downtime and maintenance, not just the difference between 100% and your SLO. By categorizing downtime into maintenance and unexpected outages, teams can identify areas for improvement, such as automating processes or fixing bugs. A real-world example shows how addressing an outdated load balancer reduced HTTP errors and restored an error budget surplus, enabling critical upgrades. Error budgets help teams focus resources on stabilizing systems, improving reliability, and meeting customer expectations.

Your choice between Sentry vs Bugsnag should depend on your team's specific needs, technology stack, and preference for either customization flexibility (Sentry) or out-of-the-box functionality (Bugsnag).

An on-call rotation is a schedule where team members are available to respond to incidents and ensure system reliability. Key elements include balanced scheduling, effective handoffs, post-mortem analysis, optimized alerting, and runbook maintenance. For global teams, the follow-the-sun model ensures 24/7 coverage, while single-region teams can rotate shifts quarterly. Tools like Squadcast, Prometheus, and Datadog streamline incident management and reduce workload. By implementing best practices, organizations can minimize downtime, improve response times, and foster a culture of reliability.
