Materials or downloads needed in advance

This is not a hands-on tutorial, so no special preparation is necessary. The tutorial will include a live demo of the full project on Cloudera'a Quickstart VM. The code for the demo will be available on GitHub so the audience can follow along.


Implementing a scalable low-latency architecture requires understanding a broad range of frameworks, such as Kafka, HBase, HDFS, Flume, Spark, SparkStreaming, and Impala among many others. The good news is that there’s an abundance of materials – books, web sites, conferences, etc. – for gaining a deep understanding of these related projects. The bad news is there’s still a scarcity of information on how to integrate these components to implement complete solutions.

In this tutorial (Part 1 of “Architecture Day”), we’ll walk through the end-to-end case study of building a fraud detection system to provide a concrete example of how to architect and implement real-time systems. We’ll use this example to illustrate important topics, such as:

  • Modeling data in Kafka, HBase, and Hadoop and selecting optimal formats for storing data
  • Integrating multiple data collection, processing, and storage systems
  • Collecting and analyzing event-based data such as logs and machine-generated data and storing the data in Hadoop
  • Querying and reporting on data

Throughout the example, best practices and considerations for architecting real-time applications will be covered. This tutorial will be valuable for developers, architects, or project leads who are already knowledgeable about Hadoop or similar distributed data processing systems, and are now looking for more insight into how it can be leveraged to implement real-world applications.
