Background - The Modern Enterprise

• Dynamic/diverse business requirements

• No single vendor or solution

• Legacy systems?

• Can’t get rid of them

• Cloud APIs

Spaghetti Integration

• Scalability, maintainability, troubleshooting?

ESB as the Integration Bus

• Clean, lean and mean.

WSO2 ESB

• A lightweight, high performance ESB

• Configuration driven over coding

• Feature rich and standards compliant– SOAP and WS-* standards– REST support– Domain specific protocol support (eg: FIX, HL7)

ESB Functional Components

Mediators

Sequences

• A chain of mediators

• Messages are sent through all the mediators in the sequence, in the order they appear

Endpoints

• A logical entity to which messages can be sent from the ESB– A service endpoint reference (EPR)– A JMS queue– A FIX session

• Various operational and QoS constraints can be engaged on an endpoint– SOAP version– WS-Security

● ESB 4.8.0 introduces the first five connectors:○ SalesForce○ Google Documents○ Twilio○ Twitter○ JIRA

● Many more connectors coming soon!

Connectors

● Opportunity Management: SalesForce + Google SpreadSheet

Sample Connector Use Case

● Searching for tweets.● Basic flow:

○ init operation - can be stored as local entry. ○ Connector operation.

Sample Connector Config

● Dynamic tooling support with Dev StudioConnector Tooling

Connectors● Connector Architecture

○ Based on Synapse Templates and Mediation Library

○ Diverse API’s (REST, SOAP, SDK) ○ Tooling with Dev Studio

● Connectors hosted on GitHub:○ https://github.com/wso2/esb-connectors/

● Anyone can create and share their own connector

Message Store/Processor Improvements

● Message processors now persist active/inactive state.

Message Store/Processor Improvements

● Forwarding Processor○ Separate intervals for message

consumption and retrying messages.

● Multiple message processors per message store

● Support for applying security policies to incoming and outgoing messages.

JSON Improvements

● Streaming JSON Builder/Formatter as default.

● Staxon library

● Works without intermediary conversion to XML

● JSON Path support for Switch, Filter, Property and Log mediators.

● Payload Factory supports mixing XPath and JSON Path.

New Mediator: Call

● Call Mediator○ Changes the way we think of service

orchestration.

○ Works like callout mediator over non-blocking HTTP.

○ Calls backend service and on response, continues mediation flow following call mediator.

○ More intuitive service chaining.

New Mediators: Respond & Loopback

● Two mediators useful during development and testing.

● Respond○ Immediate response to client sending current

message in Message Context.

● Loopback○ Move mediation flow to beginning of out flow.

Other Improvements● VFS Throttling

○ FileProcessCount○ FileProcessInterval

● New Secure Vault○ wso2:vault-lookup function. No hardcoded

secrets or passwords in ESB configs

● Streaming XPath stabilization
