WSO2 ESB Mediators

WSO2 Mediators

• Sequence: invoke a named set of sequences

• Send /Event : send a message or event

• Callout: external blocking service invocation

• Filter: Filter a message with a given Xpath

• Switch: conditionally execute mediators based on regex match

• XSLT / Smooks/ Xquery: message transformation

• Enrich: run specific actions

• DBLookup: augment message contents

• Route: content routing

• Clone / Iterate / Aggregate: message copy, splitting, and aggregation

• Cache: reduce back-end request load

• Validate: validate message content

• Rewrite: re-write URL

• Header: set header values

• Throttle: limit endpoint usage

• Log: Log a message

• DBReport: write to database

• Fault: post exception

• Drop: stop processing

• Enqueue / transaction: message queuing and transactions

• Entitlement: apply XACML policy

• OAuth: support OAuth authorization

Cloud Platform Shared Middleware Services


Cloud connectors and legacy adapters

• SalesForce.com

• Gmail

• PayPal

• Twitter

• Facebook

• SAP

• Full REST Support (XML and JSON) • Especially used in Mobile environments

• Can bridge into SOAP or other enterprise systems

• Message Relay Mode and Relay Transport • Excellent performance for 100% streaming

• Priority Execution, Cache and Throttling • Manage workloads within the ESB as well as throttle backend

• Cache content locally if appropriate

• Service Chaining • Asynchronous lightweight orchestration


Security and Identity Management

• Policy Enforcement Point (PEP) based on interoperable security

model (XACML)

• Integration with Identity providers

• Flexible OAuth authorization model


Open Business Model

• Openly published pricing

• Open License

• (i.e. 100% Apache License)

• Open product roadmap

• Open Development

• (e.g. Apache/WSO2 developer mailing lists, JIRA, architecture forum)

• Open Standards

• (e.g. Java SE, AMQP, W3C, OASIS, OpenID, Cloud Security Alliance)

• Open Architecture

• (e.g. Security, Governance, Messaging, Events, ESB, SOA, REST)

• Open Source
