Introducing the WSO2 Enterprise Integration Platform By Miyuru Wanninayaka

Software in Enterprise Large enterprises have many software systems in their “line of business” Enterprise Resource Planning systems (ERP) Management Information Systems (MIS) Decision Support Systems (DSS) Data stores Legacy systems These systems are often independent and controls one or more related business activities But they are all parts of a single business process

Need for Enterprise Integration Individual software applications cannot achieve much Systems should be integrated to work together Enables free data flow across the organization Improves production and management efficiency Application users can make better decisions

Easier Said Than Done! Integrating a multitude of complex software applications is no child's play Systems are diverse Different platforms Different programming languages Different protocols and messaging standards Different QoS requirements Not everyone adhere to standards

Point-to-Point Connections?

Bus

What is an ESB? A piece of software that resembles a data bus used in computers Provides a uniform approach for connecting systems Monitor and control routing of message exchange between services Software applications communicate via the bus The service bus acts as a carrier or a message broker Replaces direct contact between applications – Reduces coupling

WSO2 Enterprise Service Bus A lightweight, high performance ESB Configuration driven over coding REST, SOAP and WS-* support Domain specific protocol support (eg: SAP, FIX) Extensible to support custom protocols / message formats Cloud enabled Supports all EIP patterns

KEY FEATURES

Routing Simple proxy Header-based Routing Content-based Routing XPath/Property/Regular Expression Rules If/Then/Else Router mediator for complex routing

Traffic Filtering Xpath and regex based filtering Script based filtering Schema based filtering and validation foo bar foo

Service Orchestration Service chaining Split/Aggregate/ Clone/Merge Parallel/Serial execution If/Then/Else

Transformation XSLT Payload Factory Smooks XQuery E4X

Protocol & Message Format Switching Message Formats SOAP, REST, JSON, Binary Protocols HTTP(S), JMS, VFS(File), TCP, SAP, FIX, HL7, SMTP

Business/Cloud Adaptors Business Adaptors

Load Balancing

QoS : Security, Throttling, Caching WS-Security / REST Security Throttling Concurrency Rate Caching Local Replicated Suitable for idempotent operations

REST Capabilities Expose any service as RESTful APIs URL Mapping URL Templates REST

Store and Forward Store incoming request in message store In memory, JMS queue, Database Forward to backend using message processor Guaranteed delivery Message Store

Performance WSO2 ESB comes with new “Pass-through HTTP transport” Supports “pass-through” Sub millisecond latency within ESB Supports all mediation scenarios ( including content aware flows) Fastest ESB on the Earth! Streaming XPath and Fast XSLT implementation

Real World Performance – Online Shopping Use Case Billions of hits per day Only milliseconds range allowed as added latency in middleware layer WSO2 ESB instances handle external traffic loads from different functional areas Catalog, basket, checkout Channels: Web, Mobile, Desktop, Partner sites, APIs Not just “pass-through” Header based routing, XPath Zero downtime for years Inclusive daily peak hours and annual seasonal peaks Catalog Basket Checkout

Beyond ESB Just an ESB alone cannot make enterprise integration end- to-end WSO2 Middleware platform provides products to support end-to-end enterprise integration
