摘 要：Big data is an inherent feature of the cloud and provides unprecedented opportunities to use both traditional, structured database information and business analytics with social networking, sensor network data, and far less structured multimedia. Big data applications require a data- centric compute architecture, and many solutions include cloud-based APIs to interface with advanced columnar searches, machine learning algorithms, and advanced analytics such as computer vision, video analytics, and visualization tools. This article examines the use of the R language and similar tools for big data analysis and methods to scale big data services in the cloud. It provides an in-depth look at digital photo management as a simple big data service that employs key elements of search, analytics, and machine learning applied to unstructured data.
