Introducing the WSO2 Enterprise Integration PlatformBy 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

Bus

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

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

Basket Basket

Checkout 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

Business Process

• WS-BPEL 2.0 and BPEL4WS 1.1

• Long running stateful processes

• Short running stateless or stateful processes

• WS-Human Task 1.1, BPEL4People 1.1
