MapReduce is a programming model that simplifies large-scale data analysis by addressing challenges such as data redundancy, computation proximity to data, and programming complexity. It operates through two main functions: Map, which processes input key-value pairs, and Reduce, which aggregates results based on unique keys. The document provides examples of MapReduce applications, including calculating total bytes for hosts and creating an inverted index from tweets.
