Real-Time Big Data Analytics

Overview of this book

Enterprise has been striving hard to deal with the challenges of data arriving in real time or near real time. Although there are technologies such as Storm and Spark (and many more) that solve the challenges of real-time data, using the appropriate technology/framework for the right business use case is the key to success. This book provides you with the skills required to quickly design, implement and deploy your real-time analytics using real-world examples of big data use cases. From the beginning of the book, we will cover the basics of varied real-time data processing frameworks and technologies. We will discuss and explain the differences between batch and real-time processing in detail, and will also explore the techniques and programming concepts using Apache Storm. Moving on, we’ll familiarize you with “Amazon Kinesis” for real-time data processing on cloud. We will further develop your understanding of real-time analytics through a comprehensive review of Apache Spark along with the high-level architecture and the building blocks of a Spark program. You will learn how to transform your data, get an output from transformations, and persist your results using Spark RDDs, using an interface called Spark SQL to work with Spark. At the end of this book, we will introduce Spark Streaming, the streaming library of Spark, and will walk you through the emerging Lambda Architecture (LA), which provides a hybrid platform for big data processing by combining real-time and precomputed batch data to provide a near real-time view of incoming data.

Chapter 5. Getting Acquainted with Kinesis

Optimum utilization of resources has always been one of the key business objectives. It becomes more important for corporations where the cost of infrastructure is almost 50% of the overall IT budget. Cloud computing is a key concept that is changing the face of corporate IT, where it not only helps in achieving coherence and economies at scale but also provides enterprise-class functionalities such as upgrades, maintenance, failover, load balancers, and so on. Of course, all these features come at a cost, but you only pay for what you use.

It did not take much time for enterprises to realize the benefits of cloud computing and they started adapting/implementing/hosting their services and products by leveraging either IaaS ( or PaaS ( The benefits of IaaS/PaaS were so noticeable that soon it was extended to cloud...
