The document discusses how Hortonworks Data Platform (HDP) enables a modern data architecture with Apache Hadoop. HDP provides a common data set stored in HDFS that can be accessed through various applications for batch, interactive, and real-time processing. This allows organizations to store all their data in one place and access it simultaneously through multiple means. YARN is the architectural center of HDP and enables this modern data architecture. HDP also provides enterprise capabilities like security, governance, and operations to make Hadoop suitable for business use.
