12 Hadoop case studies in the enterprise
Back in 2015, analyst house Forrester predicted that enterprise adoption of Hadoop is "mandatory", so any business that wants to derive value from its data should, at the very least, be looking at the technology.
So, what is Hadoop? The open-source Apache Software Foundation describes Hadoop as "a distributed computing platform" or "a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models."
According to the foundation: "Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures."
The advantages - speed, reliability, lower costs - are appealing to the enterprise, and businesses are starting to deploy the technology at various scales.
Here is a selection of case studies from businesses deploying Hadoop at the enterprise scale, from telcos and big banks, to airlines and retailers.
