Overview of this book

We start with the perplexing task of extracting value from huge amounts of barely intelligible data. The data takes a convoluted route just to be on the servers for analysis, but insights can emerge through visualization and statistical modeling techniques. You will learn to extract value from IoT big data using multiple analytic techniques. Next we review how IoT devices generate data and how the information travels over networks. You’ll get to know strategies to collect and store the data to optimize the potential for analytics, and strategies to handle data quality concerns. Cloud resources are a great match for IoT analytics, so Amazon Web Services, Microsoft Azure, and PTC ThingWorx are reviewed in detail next. Geospatial analytics is then introduced as a way to leverage location information. Combining IoT data with environmental data is also discussed as a way to enhance predictive capability. We’ll also review the economics of IoT analytics and you’ll discover ways to optimize business value. By the end of the book, you’ll know how to handle scale for both data storage and analytics, how Apache Spark can be leveraged to handle scalability, and how R and Python can be used for analytic modeling.

Preface

The economics of predictive maintenance example


Predictive maintenance is a common value proposition cited for IoT analytics. We will walk through an example as a way to highlight how to think financially about when it makes sense and when it does not.

Situation

The economics of predictive maintenance may not be entirely obvious. Believe it or not, it does not always make sense, even if you can predict early failures accurately. It many cases, you will actually lose money by doing it. Even when it can save you money, there is an optimal point for when it should be used. The optimal point depends on the costs and the accuracy of the predictive model.

The value formula

A formula to guide decision making compares the cost of allowing a failure to occur versus the cost to proactively repair the component while considering the probability of predicting the failure:

Net Savings = (Cost of Failure * (Expected Number of Failures - Expected True Positive Predictions)) - (Proactive Repair Cost * (Expected...
