Big Data is growing rapidly in terms of volume, variety, and velocity. The cloud is well-suited to handle Big Data challenges by providing elastic and scalable infrastructure, which optimizes resources and reduces costs compared to traditional IT. In the cloud, users can collect, store, analyze and share large amounts of data without upfront investment, and scale easily as needs change. Real-world examples show how companies in industries like banking, retail, and advertising are using the cloud's Big Data services to gain insights from large datasets.
