Abstract

Cloud Control Systems - Real Time Analytics

Simon Tuffs, consultant

Abstract:  

Presentation slides

Event Driven, Service-Oriented Cloud Systems can be viewed as systems of multi-variable time-series data.  This makes them amenable to analysis using discrete-time signal-processing and feedback control systems analytic techniques.  Some illustrative examples from a real-world Cloud System are presented: Anomaly detection and classification using statistical tests, correlation, and causal inference based on service dependencies; Qualification of new code deployments into production, automated failure detection and recovery; and Auto-scaling challenges and remedies, with use of feed-forward predictors to survive outages,  A general architecture for Cloud Systems Analytics is presented, together with a view of the interesting challenges ahead.
