Service Oriented Architecture in Enterprise

Application

OverviewEnterprise ApplicationEvolution of Enterprise ArchitecturesService Oriented Architecture (SOA)Implantation of SOA in Enterprise ApplicationsReferences.

What is Enterprise Application?

Enterprise Application

Monolithic Applications Applications are strong coupling.

Component Based Architecture Related functionalities of an application are group

together and components were created.

To interact with other application needs to implement new interfaces.

Enterprise Application Integration (EAI) Possible by middleware technology like Common

Object Request Broker Architecture (CORBA).

Evolution of Enterprise Architectures

Separation Of GUI Increase flexibility but needs new technologies

Business- IT Alignment - Basic Services Service registry was introduce

Hard-Wired Service Orchestration Problems in getting the flow of process control

Soft-Wired Service Orchestration Introduce orchestration engines

Evolution of Enterprise Architectures (continue…)

SOA Defined “paradigm for organizing and utilizing distributed

capabilities that may be under the control of different ownership domains”[4]

SOA Model

Service Oriented Architecture (SOA)

SOA is Architecture

Helps interoperability and woks in heterogeneous environment.

Service identification Same business function provides by many providers SOA requires that developers discover at development

time service descriptions in (UDDI) repository systems To address these “quality of service management

framework” introduced.Service location

Services operate on business entities, occupant within system records

Challenges in implementing SOA in Enterprise Application

Basic SOA UDDI provides a simple browsing- by-business-category mechanism discovery based on keyword-search Introduced Hybrid matching approach

Combining semantic and syntactic comparison algorithms of WSDL documents

Functional layer challenges Service definitions addressing Functional, non-functional aspects associated with

services

service trading executed in several stages offer descriptions are not completely specified in most

cases and different parameters have to be supplemented by the service requestor and provider alternately.

introduce the concept of partially instantiated service descriptions
