New technologies abound and are constantly emerging in the big data world. Today, a greater variety of data than ever before is being collected, stored, and analyzed by more users. Smart machines are spurring immediate action with sensors streaming data across the Internet of Things. Big data processing is being done on Hadoop, Apache Spark, and other frameworks with data often stored in open source and NoSQL database platforms in addition to established relational database systems. And, supporting all that diversity of choice for handling data is the cloud, which is often seen as the antidote to growing IT complexity.
