  Introduction In today’s digital economy, organizations generate and store data from countless sources: enterprise applications, IoT devices, cloud services, customer interactions, and third-party systems. This data, often vast and heterogeneous, needs to be integrated before it can drive insights. Traditional approaches to data integration—manual ETL (Extract, Transform, Load) processes, rule-based pipelines, and custom scripts—are time-intensive, error-prone, and lack adaptability. Agentic AI , a new paradigm of autonomous and proactive artificial intelligence, is transforming this landscape. By automating integration processes, Agentic AI reduces human intervention, ensures data consistency, and enables real-time decision-making in big data platforms. Challenges in Traditional Data Integration Complexity of Sources – Data comes in structured, semi-structured, and unstructured formats. Scalability Issues – Manual pipelines often fail to handle petabyte-scale work...

  Introduction In the era of Big Data, organizations collect massive volumes of structured and unstructured data from diverse sources. However, raw data is rarely perfect. It often contains errors, missing values, duplicates, or inconsistencies that compromise its quality and reliability. Data cleaning, also known as data preprocessing, is therefore a crucial step in any Big Data project. Traditional approaches to data cleaning are often manual, rule-based, and time-consuming.  With the advent of Agentic AI , a new paradigm is emerging—one that automates, adapts, and optimizes data cleaning at scale. What is Agentic AI? Agentic AI refers to artificial intelligence systems that operate with goal-driven autonomy , capable of perceiving their environment, reasoning about tasks, and taking actions without continuous human oversight. Unlike static machine learning models, Agentic AI agents can dynamically adapt to new conditions, negotiate trade-offs, and optimize workflows i...

  Introduction In today’s data-driven world, organizations face the challenge of processing vast amounts of data efficiently and reliably. Big data pipelines are critical for transforming raw data into actionable insights, but traditional approaches often struggle with scalability, adaptability, and maintenance. Agentic AI—autonomous, goal-oriented systems capable of decision-making and task execution—offers a transformative solution. This chapter explores how to design and implement scalable big data pipelines using agentic AI, focusing on architecture, tools, and best practices. Understanding Big Data Pipelines A big data pipeline is a series of processes that ingest, process, transform, and store large volumes of data. These pipelines typically involve: Data Ingestion : Collecting data from diverse sources (e.g., IoT devices, databases, APIs). Data Processing : Cleaning, transforming, and enriching data for analysis. Data Storage : Storing processed data in scalable systems ...

  Introduction to Big Data and Cloud Integration The explosion of data in modern applications—ranging from IoT sensors to financial transactions—has driven the need for scalable, efficient, and cost-effective solutions for data processing and storage. Big data integration with cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) provides organizations with the tools to manage massive datasets, process them in real time or batch, and store them securely. These platforms offer managed services that simplify infrastructure management, enabling data engineers to focus on analytics and insights. This chapter explores how to integrate big data workflows with AWS, Azure, and GCP, covering their key services, architectures, and practical examples. We’ll provide code snippets and configurations to demonstrate how to build scalable data pipelines for processing and storage, along with best practices for optimizing performance and cost. Why Use C...

  Introduction to Apache Spark and Cluster Deployment Apache Spark is a powerful open-source framework for big data processing, known for its speed, scalability, and ease of use in handling large-scale data analytics. However, setting up and managing Spark clusters—especially in distributed environments—can be complex, involving tasks like provisioning hardware, configuring software, and ensuring scalability and fault tolerance. Automated deployment tools and practices streamline this process, enabling data engineers to deploy Spark clusters efficiently and focus on analytics rather than infrastructure management. This chapter explores the automation of Spark cluster deployment, covering tools, techniques, and best practices for streamlining the setup of distributed computing environments for big data applications. We’ll provide practical examples, including scripts and configurations, to demonstrate how to automate Spark cluster deployment in cloud and on-premises environments....
