Projects07 Reliability
SRE Reliability Platform
SLIs, SLOs, and error budgets connected to burn-rate alerts and incident follow-up.
Problem
Telemetry existed, but it did not turn into reliability decisions. SLIs, error budgets, and incidents lived in different places.
Solution
Built a reliability platform that calculates SLIs, evaluates SLOs, tracks error budgets, detects burn-rate conditions, and ties an incident back to a reliability action.
Architecture
- Telemetry
- SLI
- SLO
- Error budget
- Burn rate
- Incident
- Reliability action
Technology
- Prometheus
- Grafana
- Python
- Kubernetes
- OpenTelemetry
Engineering decisions
- SLIs that measure the user-visible failure, not an easy internal counter.
- Burn-rate alerts that fire early enough to act and late enough to stay quiet.
- A clear owner for each service so an alert is not ownerless.
- Joining an incident to the SLO it burned, not only to a ticket number.
- A reliability report that a team can read without another slide deck.
Automation
Burn-rate conditions open the incident path and attach the SLO context. Post-incident actions are tracked against the same service.
Reliability
If the SLI query fails, the platform says the budget is unknown rather than drawing a green chart from empty data.
Security
Service ownership and alert routes are data, not a spreadsheet on someone's laptop. Access to budget views follows the same roles as the dashboards.
