Advanced SRE Topics
- On-call health — Track alert volume, on-call interruptions. More than 2 pages/shift = overloaded. Fix noisy alerts
- Toil automation — Automate repeated tasks: certificate renewal, database failover, scaling. Goal: zero-touch operations
- Multi-region architecture — Active-active vs active-passive. Global load balancing (Route 53, Cloudflare). Data replication strategy
- Disaster recovery — RTO (Recovery Time Objective): how fast to recover. RPO (Recovery Point Objective): how much data loss acceptable
- Database reliability — Read replicas for read scaling. Connection pooling (PgBouncer). Automatic failover with managed services
- Load testing — k6, Locust, Apache JMeter. Test before launches, peak events. Find breaking points, not just average load
- Synthetic monitoring — Uptime Robot, Datadog Synthetics. Test from multiple regions. Alert before users notice problems
