Apache Hadoop is an open-source software framework for storage and large-scale processing of business data. The software breaks data into a workable size that programmers can then structure, organise, study or visualize. Prominent users of Hadoop software include Google, Facebook and Yahoo!.
Research undertaken by Allied Market Research suggests that the market for using Hadoop in the cloud (“Hadoop as a Service”) is projected to grow to $16.1 billion by 2020. Allied Market Research’s report defines Hadoop as a Service as “a method of using Hadoop technology without physical installation of the infrastructure on premises”. Key issues however in relation to data security in the cloud remain a concern for customers and cloud service providers alike.
The Wall Street Journal reported in April that Hadoop is gaining traction as a key tool companies can use for data management.
