Big Data Architecture for Large Organizations

Abstract: The exponential growth of big data has transformed how large organisations leverage information to drive innovation, optimise processes, and maintain competitive advantages. However, managing and extracting insights from vast, heterogeneous data sources requires a scalable, secure, and well-integrated big data architecture. This paper proposes a comprehensive big data framework that aligns with organisational objectives while ensuring flexibility, scalability, and governance. The architecture encompasses multiple layers, including data ingestion, transformation, storage, analytics, machine learning, and security, incorporating emerging technologies such as Generative AI (GenAI) and low-code machine learning. Cloud-based implementations across Google Cloud, AWS, and Microsoft Azure are analysed, highlighting their tools and capabilities. Additionally, this study explores advancements in big data architecture, including AI-driven automation, data mesh, and Data Ocean paradigms. By establishing a structured, adaptable framework, this research provides a foundational blueprint for large organisations to harness big data as a strategic asset effectively.
