Starting point & goal
A mid-sized fintech runs a real-time trading system where every minute of downtime costs money directly. Incidents were handled reactively and ad hoc — without clear metrics and without dependable alerting.
Challenges
- Mean time to recovery of 47 minutes for critical incidents
- No shared understanding of availability: SLOs were missing
- Alert fatigue from hundreds of unprioritised alerts
- High load peaks at market open
Implementation
We established an SLO framework that makes availability measurable and built an observability stack that shows causes instead of symptoms. Runbooks, on-call processes and regular chaos-engineering exercises keep the team ready to act — before the emergency happens.
