Software in Enterprise

• Modern day business organizations have many software systems

• Enterprise resource planning solutions

• Management information systems

• Decision support systems

• Tools for research, development and testing

Reality Check…

• Enterprises have many reasons for using software

• Saving time and resources

• Automating complex and repetitive tasks

• Detecting problems quickly and reacting to them

• But most software deployments don’t even come close to realizing these goals

What’s Wrong with Software?

• Nothing really – We are not using them right

• A business is comprised of many related activities and processes

• These should be carried out in perfect unison

• Software systems that look after individual business aspects do not see this big picture

• ‘Narrow minded’ systems often obstruct productivity than improve

A Couple of Examples…

• The supply chain management system should keep an eye on the inventory management system

• Decision support systems cannot help make useful decisions without insight to all the aspects of the business

And the Solution is…

• Integrating systems and applications together

• Get software systems to work in perfect synchronism with each other

• Let applications see the bigger picture and enable them to take the right action at the right moment

• These requirements lead to………..

Enterprise Application Integration

• Integrating enterprise computer applications using software and computer systems architectural principles

• Not limited to integration within an organization

• Integrating with customer applications

• Integrating with supplier/partner applications

• Integrating with public services

Easier Said Than Done

• EAI is often one of the hardest problems to crack

• Enterprise applications are diverse

• Different programming languages (C, Java, C#)

• Different protocols (HTTP, AMQP, FIX)

• Different platforms (J2EE, .NET, LAMP)

• Different message formats (XML, SOAP, JSON)

• Different QoS requirements (security, reliability)

If We are Not Careful…

ESB to the Rescue

• A software architectural construct which provides fundamental services for complex architectures

• Resembles a data bus used in computers

• Provides a uniform approach for integrating systems

• Reduces point-to-point connections between systems and reduces coupling

ESB in Action

Introducing WSO2 ESB

• A lightweight, high performance ESB

• Feature rich and standards compliant

• SOAP and WS-* standards

• REST support

• Support for generic protocols (HTTP/S, JMS…)

• Domain specific protocols (FIX, AMQP…)

• Easy to configure (Zero code development)

• Easy to extend (Clean APIs where necessary)

Lightweight to the Core

• The entire binary distribution is sized ~150 MB

– Download Extract Run

• No special tools or IDE required

– Use the built-in management console or go old school by manually editing the configuration files

• Implement complex messaging scenarios and integration patterns within minutes

– Powerful mediation features and flow constructs

• Low CPU utilization and small memory footprint

Functional Components

• Mediators

• Sequences

• Endpoints

• Proxy services

• Event sources

• Priority executors

• Message stores

• Tasks

• Local entries

• Registry

• REST APIs

• Message stores

• Templates

Mediators

• The basic message processing unit in the ESB

• Each mediator performs a predefined task on the input messages

• WSO2 ESB ships with many mediators

• Core mediators (Log, Send, Drop)

• Transformation mediators (XSLT, XQuery)

• Filtering mediators (Filter, Switch)

• Advanced mediators (Clone, Iterate)

WSO2 ESB Messaging Model

• Uniform view of “messages” regardless of underlying protocol and message format

• Pipes and filters model for message flow control • Filters Mediators

• Pipes Sequences

• Non-blocking, stateless, asynchronous messaging – High performance by design – 1 Billion transactions a day at eBay alone

Configuring the ESB

• The task of laying out ESB functional components and configuring them

• Done using the Synapse configuration language (XML based)

• WSO2 ESB makes the job easier by providing a set of UI wizards and graphical tools

• Equivalent to programming in many ways
