SOA
Service Oriented Architecture


SOA Definition

“ Wikipedia

In software engineering, a Service-Oriented Architecture is a set of
principles and methodologies for designing and developing software in the
form of interoperable services. These services are well-defined business
functionalities that are built as software components that can be reused
for different purposes. SOA design principles are used during the phases of
systems development and integration.

Corporate Jargon
CRM
Customer relationship management is a widely implemented strategy for managing a company’s
interactions with customers, clients and sales prospects.

SCM
Supply chain management is the management of a network of businesses involved in the provision of
product and service packages required by end customers. It spans all movement and storage of raw
materials, work-in-process inventory, and finished goods from point of origin to point of consumption.

ERP
Enterprise resource planning systems integrate internal and external management information across
an entire organization. ERP systems automate this activity with an integrated software application. Their
purpose is to facilitate the flow of information between all business functions inside the boundaries of the
organization and manage the connections to outside stakeholders.

ERP
Enterprise Application Integration is an integration framework composed of a collection of technologies
and services which form a middleware to enable integration of systems and applications across the
enterprise.
17

Principles
Loose Coupling
Services maintain a relationship that minimizes dependencies and only requires that they maintain an
awareness of each other.

Abstraction
Beyond descriptions in the service contract, services hide logic from the outside world.

Granularity
A design consideration to provide optimal scope and right granular level of the business functionality in a
service operation.

Statelessness
Services minimize resource consumption by deferring the management of state information when
necessary.

Discoverability
Services are supplemented with communicative meta data by which they can be effectively discovered
and interpreted.

Communication Interfaces

Mesh Network Star Network
Alot of different interfaces Much less interfaces

19

Enterprise Service Bus (ESB)

20

ESB Functionalities
Location Decoupling
An ESB provides decoupling between the requesting and receiving party, this is to connect new and modify existing
services easier.

Technical Translation
The ESB also provides technical translation. The ESB can communicate in many different channels such as HTTP, FTP,
JMS, SOAP, File and more.

Transform Messages
The ESB must also be able to translate messages from one format to another. This includes features such as XSLT or
XQuery.

Routing Messages
Determining the final destination of a message is an important functionality of an ESB. This may be based on the content of
a message, according to a fixed list or many other ways.

Security
Authentication, authorization and encryption capabilities are all things that an ESB must supported.

Management and monitoring
When the ESB-based solution is up and running it should also be manageable. This is also an important feature of an ESB.

Key Web Service Standards
XML (eXtensible Markup Language)
Open human readable standard for representing structured data.

SOAP (Simple Object Access Protocol)
Open XML-based protocol for transmitting web service requests and responses between systems. Can
include complicated Structured data in the messages.

WSDL (Web Service Description Language)
Open XML-based format for describing Web Services. Describes the “interface contract” for a web service
(expected Parameters, inputs, outputs).

UDDI (Universal Description Discovery and Integration)
Open XML-based directory format that advertises the availability And location of Web Services.

23

Web Service != SOAP
XML-RPC
A remote procedure call (RPC) protocol which uses XML to encode its calls and HTTP as a transport
mechanism.

JSON-RPC
A remote procedure call protocol encoded in JSON.

BPM
Business Process Management


BPM Definition

“ Wikipedia

Business process management is a holistic management approach
focused on aligning all aspects of an organization with the wants and needs
of clients. It promotes business effectiveness and efficiency while striving for
innovation, flexibility, and integration with technology. BPM attempts to
improve processes continuously. It can therefore be described as a
"process optimization process." It is argued that BPM enables organizations
to be more efficient, more effective and more capable of change than a
functionally focused, traditional hierarchical management approach.

Building The Stack : Top/Down
Steps
1. Identify Business Processes
2. Identify Services within Processes
3. Identify Component Services
4. Link Components to Application Services
5. Implement Services

Risks
 Time consuming
 Little focus on reuse of existing IT
 Services often too specific for reuse

34

Building The Stack : Bottom/Up
Steps
1. Analyze existing applications
2. Identify patterns in current usage
3. Group patterns in services
4. Document service functionality
5. Expose documented services via generic interface

Risks
 Little focus on business needs
 Service granularity relatively low
 Proliferation of small, invaluable services can lead to performance problems

35

Process Flow


Business Process Execution Language (BPEL)

 Web Service Orchestration
 BPEL = WS-BPEL

 Long running processes (seconds to months)

 Human tasks
