Build SOA-based flexible, economical, and efficient applications.

• Develop SOA applications using the WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB)
• Analyze business requirements and rationalize your thoughts to see if an SOA approach is appropriate for your project
• Quickly build an SOA-based Order Management application by using some fundamental concepts and functions of WPS and WESB
• Do a top-down decomposition of the Order Management application to identify use cases, business processes, and services/components

In Detail

By adopting an SOA approach in Business Process Management (BPM), you can make your application flexible, reusable, and adaptable to new developments. The SOA approach also gives you the potential to lower costs (from reuse), and increase revenue (from adaptability and flexibility). However, integrating basic SOA constructs (such as Process, Business Services, and Components) and core building blocks of BPM (such as Process Modeling and Enterprise Service Bus) in a real-world application can be challenging.

This book introduces basic concepts of Business Integration, SOA Fundamentals, and SOA Programming Model and implements them in numerous examples. It guides you to building an Order Management application from scratch using the principles of Business Process Management and Service Oriented Architecture and using WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB). The various detailed aspects, features, and capabilities of the product are conveyed through examples

We begin with essential concepts on Business Integration, SOA Fundamentals and SOA Programming Model. Then we set up the development environment to build your first Hello Process and Hello Mediation applications.

Gradually, we build an SOA-based Order Management Application. We cover important aspects and functions of WPS and WESB with numerous practical examples. We show how to analyze your application's business requirements and check if an SOA approach is appropriate for your project. Then you do a top-down decomposition of your application and identify its use cases, business processes, and services.

Having built the SOA Application, we introduce you to various non-functional topics, including: Administration, Governance, Management, Monitoring, and Security. We also discuss deployment topologies for WPS and WESB, performance tuning, and recommended practices.

A practical guide to creating, developing, and analyzing project modules and examining deployment topologies for WPS and WESB

What you will learn from this book

• Deliver an SOA infrastructure in WebSphere Process Server to orchestrate, mediate, connect, map, and execute the underlying IT functions and systems
• Provide a smart approach to SOA by enabling connectivity and messaging capabilities in a WebSphere Enterprise Service Bus
• Install and set up your integrated development environment--WebSphere Integration Developer (WID)
• Perform the various basic tasks (such as creating workspaces and projects, working with modules, exporting and importing projects) to build, test and deploy SOA-based BPM and integration solutions across WPS, WebSphere ESB, and WebSphere Adapters
• Build and deploy your first module project in WID and test business process applications
• Implement basic concepts of mediation and mediation flows in a simple HelloMediation module
• Deploy and execute mediation modules to test them in a WID unit test environment
• Select and use the right tool from the toolbox to build, unit test, and debug applications for WPS
• Perform typical tasks such as build, test, configure, and deploy ESB-based applications from WID
• Assemble components of the IBM SOA reference architecture and create shared libraries that can then be leveraged by the different modules of a Sales Fulfillment application
• Build the Business Services and Access Services and perform end-to-end integration tests on these business processes
• Integrate this business process with existing applications and legacy systems using various tools available with WebSphere Business Management Systems
• Manage, monitor, secure, and administer your modules with the tools provided by WPS and WESB
• Migrate applications, modules, and mediations from one environment to another
