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

Managing data lakes


Data lakes are places used to dump tons of potentially valuable data from multiple sources. Some sources will be IoT devices, while some sources will be internal company data such as production, purchasing, or customer service records. The concept is to put all of this variety of data in one place so it can be accessible through a unified interface. In the case of Hadoop, the data lake would be stored in HDFS and probably accessed through Hive or Spark.

When data lakes turn into data swamps

Swamps are formed when water flows into an area where it collects and stagnates. Algae covers over the water. When a data lake has a mass of raw data flowing in but no organization and little usage of it to mix up the waters, it becomes what is facetiously referred to as a data swamp.

This often happens when the decision is made to copy data from many systems into one area, such as HDFS, without any changes to it. Analysts can find it difficult to access due to security restrictions....
