Designing Big Data Platforms
John Wiley & Sons Inc (Verlag)
978-1-119-69092-4 (ISBN)
An array of tools are currently available for managing and processing data—some are ready-to-go solutions that can be immediately deployed, while others require complex and time-intensive setups. With such a vast range of options, choosing the right tool to build a solution can be complicated, as can determining which tools work well with each other. Designing Big Data Platforms provides clear and authoritative guidance on the critical decisions necessary for successfully deploying, operating, and maintaining Big Data systems.
This highly practical guide helps readers understand how to process large amounts of data with well-known Linux tools and database solutions, use effective techniques to collect and manage data from multiple sources, transform data into meaningful business insights, and much more. Author Yusuf Aytas, a software engineer with a vast amount of big data experience, discusses the design of the ideal Big Data platform: one that meets the needs of data analysts, data engineers, data scientists, software engineers, and a spectrum of other stakeholders across an organization. Detailed yet accessible chapters cover key topics such as stream data processing, data analytics, data science, data discovery, and data security. This real-world manual for Big Data technologies:
Provides up-to-date coverage of the tools currently used in Big Data processing and management
Offers step-by-step guidance on building a data pipeline, from basic scripting to distributed systems
Highlights and explains how data is processed at scale
Includes an introduction to the foundation of a modern data platform
Designing Big Data Platforms: How to Use, Deploy, and Maintain Big Data Systems is a must-have for all professionals working with Big Data, as well researchers and students in computer science and related fields.
Yusuf Aytas is an experienced software engineer. He holds a Master and Bachelor of Computer Science from Bilkent University, Ankara, Turkey. Yusuf has experience in building highly scalable, optimized analytics platforms. He is proficient in agile methodologies, continuous delivery, and software development best practices.
