Data Lake for Enterprises

By: Vivek Mishra, Tomcy John, Pankaj Misra

Overview of this book

The term "Data Lake" has recently emerged as a prominent term in the big data industry. Data scientists can make use of it in deriving meaningful insights that can be used by businesses to redefine or transform the way they operate. Lambda architecture is also emerging as one of the very eminent patterns in the big data landscape, as it not only helps to derive useful information from historical data but also correlates real-time data to enable business to take critical decisions. This book tries to bring these two important aspects — data lake and lambda architecture—together. This book is divided into three main sections. The first introduces you to the concept of data lakes, the importance of data lakes in enterprises, and getting you up-to-speed with the Lambda architecture. The second section delves into the principal components of building a data lake using the Lambda architecture. It introduces you to popular big data technologies such as Apache Hadoop, Spark, Sqoop, Flume, and ElasticSearch. The third section is a highly practical demonstration of putting it all together, and shows you how an enterprise data lake can be implemented, along with several real-world use-cases. It also shows you how other peripheral components can be added to the lake to make it more efficient. By the end of this book, you will be able to choose the right big data technologies using the lambda architectural patterns to build your enterprise data lake.

Disadvantages of Lambda Architectures


Choosing a Lambda Architecture to develop a Data Lake for your enterprise does incur some inherent disadvantages if some of its aspects are not fully thought through. Some of these are as follows:

  • Due to its different layers, it is generally considered to be complex. Keeping sync between these two layers incurs cost and effort, and this has to be thought through and handled.
  • Because of these two distinct and fully distributed layers (batch and speed), maintenance and support activities are quite hard.
  • There are a good number of technologies that have to be mastered to construct a Lambda-Architecture-driven Data Lake. Getting people who have expertise in these technologies can be troublesome for your recruitment division.
  • Implementing a Lambda Architecture with open sources technologies and then deploying in the cloud can be troublesome. To avoid this, you could very well use cloud technologies to implement Lambda Architecture, but by doing so, the enterprise...
