In this article, we propose Palisade, a distributed framework for streaming anomaly detection. Palisade is motivated by the need to apply multiple detection algorithms for distinct anomalies in the same scenario. Our solution blends low latency detection with deployment flexibility and ease-of-modification. This work includes a thorough description of the choices made in designing Palisade and the reasons for making those choices. We carefully define symptoms of anomalies that may be detected, and we use this taxonomy in characterizing our work. The article includes two case studies using a variety of anomaly detectors on streaming data to demonstrate the effectiveness of our approach in an embedded setting.
