Anomaly Detection - Fault Tolerance - Anticipation Patterns

Sharing the four cornerstones of anomaly detection, fault tolerance and anticipation pattern. I came across this in one of the many presentations floating on the web.

1. Anticipation - Knowing What To Expect

- During choice of technologies
- During design of monitoring and metrics
- During design of architecture

2. Monitoring - Knowing What To Look For
3. Response - Knowing What To Do
4. Learning -Knowing What Has Happened

Areas of redundancy -

Spatial (server, network, process)
Temporal (checkpoint, “rollback”)
Informational (data in N locations)
