Anomaly detection for monitoring has been a trending topic in recent years. And while the math behind it is fascinating, too much of the discussion has revolved around histograms, moving averages and standard deviations. More discussion needs to happen around its practical applications, and for that reason, this practical guide to anomaly detection will attempt to provide an actionable overview of current off-the-shelf anomaly detection tools.

In the last two decades, with the emergence of cloud infrastructure and SaaS delivery models, the monitoring ecosystem has changed dramatically to include over 100 monitoring solutions. The upside of that change is the rapid implementation of monitoring infrastructure, but the unintended consequence of this is that the tools themselves decide what IT measures.

This is part two of a two-part post about using event correlation to thwart DDoS attacks. Channeling Mark Twain: it would have been shorter if I had more time. In the last post I described why DDoS attacks for SaaS providers are no different than performance and availability issues experienced in other domains like healthcare, finance, or retail. In this post I’ll share a customer story about a security breach that never happened… thanks to a savvy DevOps team and data science.
