What is SOA?

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

The “Move” to Service Orientation
Accidental Layered
Rigid Extensible
Silo-Oriented Service-Oriented

Layering Principle
• Shared Network-based Layered Services
Access Layer
Process Layer
Service Layer
Resource Layer

SOA Architecture Layers

SOA Architecture Layers
• Resources
– Operational Resources; e.g. CRM, ERP, HR,
Databases
– Enterprise components; technologies e.g.
Java, .NET, CORBA, PHP
• Services
– Selected components which have been
developed as services
– Can implement various way; e.g. Web
Services
– Normally has well defined interface; e.g.
WSDL

SOA Architecture Layers
• Business Process
– Represent powerful orchestration of one or
more services that solve a business problem
– Business Process itself is a service of services
• Access
– Front or User Interface that calls business
process
– Web Programming, Desktop, Dashboard
– Can be implemented to run on various
devices

Reuse Services via Re-composition

The most important SOA concepts
• Services
• Composition of services into business processes
• Exchange of messages
• Support for synchronous and asynchronous
communication
• Loose coupling
• Service registries
• Quality of service
• Self-describing interfaces with coarse granulation

SOA Value Proposition
• Reducing integration expense
– Both development and maintenance cost by
isolating components and systems through
well-defined interfaces and proper
architecture layering.
• Increasing asset reuse
• Increasing business agility
– Simplified Business Integration
• Reducing business risk
– Both operational and compliance risk

SOA Value Proposition
• Faster time to market
• Align IT and Business Units
• Visible Business Process

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.

ESB
 Enterprise
Service Bus (ESB) is the software
middleware
 ESBacts as a mediator between different,
often incompatible protocols and middleware
products
 ESB is the backbone of SOA
 You can't buy SOA, but you can buy an ESB

The role of ESB in SOA

Features of an ESB
• Web Services Support
– ESB offers an ability to invoke SOAP and WSDL based
Web Services
• Adapters
– Many ESB vendors will provide adapters to integrate
with different thrd-part applications, such as
PeopleSoft, SAP
– Used for applications which do not directly have
SOAP or XML interface
• Invocation
– ESB supports synchronous and asynchronous calls
to services and sometimes callbacks

Features of an ESB (Cont.)
• Mediation and protocol independence
– Variety of protocols can be reconciled for complex
route across a variety of platform
– Allows to connect with different protocols such as
HTTP, FTP, SMTP, JDBC
• Routing
– Allows us to route the messages to different services
based on their content, origin or other attributes
• Transformation
– Data represented as XML can be transformed using
XSLT or XQuery before they are delivered to services.
– Some ESB supports various XML, e.g. HL7, SWIFT

SOA Using GlassFish ESB

Challenges with Legacy ESBs
Most are proprietary and closed source
> No transparency into vendor development
process
– Complex and risky upgrade process
> Complete control by vendor
– Vendor lock-in
– Customers/partners unable to influence platform
direction
> Can't easily incorporate external innovation
– Difficult for partner/customer to include value-added
differentiation

A Need for Two Approaches
• Complex ESB
– Purpose:
• Highly complex requirements, A

solution
– Target Usage: can be overkill
• Enterprise-wide infrastructure for a small
project
• Lightweight ESB
– Purpose
• For rapid deployment
The right tool
– Target Usage for the right
• Specific project, narrow initial focus job

“We Already Have an ESB”
• ...so why a new ESB?
– Need to react faster, lower risk
– High costs, risk, complexity, and lack of agility
• Strategy: For all new projects
– Federate with existing ESB
– Lower costs and risks and increase agility with lightweight ESB

Why EAI in Healthcare is here to stay
• SOA generates demand
for EAI service and data discovery
• NPfIT programme requires EAI for existing systems to
fulfil national and regional SOA services
• EAI firmly established as healthcare core IT skill since
1996
• Existing customers need to upgrade as older SeeBeyond
products are EOLed
> Healthcare integration standards (HL7
v2/v3, etc) still messaging based, see
example HL7 v3 schema :

Healthcare CIO awareness of SOA is
rising
• Nearly all UK hospitals have EAI platforms for:
– HL7 version 2 - ubiquitous
– HL7 version 3 – mainly around NHS Spine
• Desire for Healthcare SOA capability is strong:
– UK National Programme is forcing uptake of
national and regional services
– Cost pressures forcing NHS to develop shared
services
– Government agenda for NHS reform demand
greater agility from IT
– Increasing involvement of private sector care
• More press coverage of healthcare SOA
