5. Hype or Reality?
Loosely Coupled Register & Discover
Federation XML On Demand
The New EDI? Agile
QoS Flexible IT Web Services
Remember CORBA?
Standards Aligned So What? Wrap & Reuse
Layering
Transformation
SOA!? Autonomous
Messaging Cross-Platform Multi-Vendor
Reuse Vendor Neutral Stateless
Composability Interoperable Legacy
Location Transparency
Encapsulate
Integration Described Extensible
5

6. What is SOA?
Principles and practices for designing shared,
reusable, distributed services
SOA Attributes:
> Separation of service interface from underlying
implementation (loose coupling)
> Promotes service reuse through discoverable and
self-describing services
> Services are course-grained, composable, and rely
on a standards based infrastructure

7. Accidental Architecture?
Silo Oriented Architecture
Mature information systems grow
old disgracefully as successive
waves of hacking result in
accidental architectures which
resist the reflection of on-going
business process change.
- Anthony Lauder & Stuart Kent;
University of Kent. (2000)
 Rigid
 Complex
 Expensive
 Slow to Market
 Monolithic
 Hard to Integrate

35. SOA Implementation
• Services Implementation
– Various Programming
– Web Services
– Non Web Services; Legacy via adaptors
– Data Services => JDBC
• Message Exchange => XML Schema
• Self-describing interface => WSDL
• Comunication of Services & Management => ESB
• Service Orchestration => BPEL, Human Workflow
• Presentation => Portal, Web Programing 35

42. Why ESB?
• In most enterprise, Web Services are not the only
middleware solution.
– Only SOAP is not adequate for services connection
• Other middlewares products, messaging servers, Java
EE, ORBs, Databases etc..
– Other binding communication protocols may be need;
such as JDBC, JMS, Files, SMTP,MSMQ
• ESB acts as an intermediary layer of middleware to
communicates between services using various
protocols.
42

43. ESB : Features
• Provides communication between services via
different protocols (Not only HTTP/SOAP)
• Message interception capabilities
• Routing capabilities
• Transformation capabilities
• Control over the deployment, usage and maintenance
of services
• Other important managements,

52. What is it?
Business Processes Management
The concept of Business Process Management [BPM] has its roots in
Operation Transformation and enables flexible design deployment,
monitoring and tracking, process focus and efficiency.

54. BPEL
• Business Process Execution Language
• Based on XML
• IBM, BEA and Microsoft developed the first version
in 2002
• BPEL 2.0 is latest version
54

55. BPMN
55

56. BPEL Designer Tools
• IDE can be used to write BPEL or BPMN
• Examples:
– NetBeans 6.1/6.5
– Eclipse
– Oracle Jdeveloper 10g
– IBM WebSphere Studio
56

57. BPEL Server
• Provides a run time environment for executing BPEL
• Examples
– GlassFishESB (via BPEL SE)
– Oracle BPEL Process Manager
– Microosoft Biztalk
– Sun Java CAPS
– IBM WebSphere Business Integration Server
– Active BPEL Engine
– Apache Agila

69. Disadvantages of Open Source SOA
Having spoken about the various open source alternatives to
implement SOA into an enterprise we must also gauge the
various risks and disadvantages associated with the Open
source approach. Here are a few of them:-
Most open source software applications are not reliable
No support exists for open source software
No guarantee of updates
Significant problems connected to intellectual property
69

70. GlassFish Portfolio
• Buying Support for OpenSource software
• GlassFish Enterprise Server => GlassFish V2
• GlassFish ESB => OpenESB
• GlassFish Webspace => Liferay
• GlassFish Enterprise Monitor
• NetBeans Tools
