This document discusses trends in storage technologies including software-defined storage, distributed object storage, and key-value storage. It notes that software is increasingly disrupting traditional storage models and that data is becoming more distributed and dynamic. Various current and emerging storage solutions are mentioned, as well as different architectures like distributed object stores, key-value databases, and file systems. The document advocates for data to break free of storage constraints and flow more freely.
