The document provides an overview of the WSO2 ESB product and the new features in version 4.7.0. It discusses how WSO2 ESB enables integration through an enterprise service bus and components like mediators, sequences, endpoints and proxy services. It also demonstrates the product's capabilities for routing, filtering, transformations and protocol switching with a sample pizza ordering application. New features in 4.7.0 include improvements to RESTful integration support, message store/processing and SSL tunneling between the ESB and backends.
