Big Data Concept

  Introduction In the realm of big data, storage is the foundational pillar that enables organizations to capture, retain, and access vast amounts of information efficiently. As data volumes explode—driven by sources like social media, IoT devices, sensors, and enterprise transactions—the limitations of traditional storage systems become glaringly apparent. This chapter delves into the technologies and infrastructures that make big data manageable, focusing on storage solutions designed to handle the "three Vs" of big data: volume, velocity, and variety. We begin with an overview comparing traditional and modern storage approaches, followed by an introduction to distributed file systems and databases. Subsequent sections explore key technologies such as the Hadoop Distributed File System (HDFS), NoSQL databases like MongoDB and Cassandra, the distinctions between data lakes and data warehouses, and cloud-based storage options including AWS S3 and Azure Blob Storage.
