Therefore, empirical studies are needed to evaluate the value of SOA. This paper reports on a first attempt to attain empirical evidence regarding the benefits of SOA. These two technologies were compared on the basis of code size and development time. The main contributions of this paper are: This technology deals with server-side components that adhere to standards in order to attain high degree of reusability.
EJBs run within middleware application servers that provide enterprise-level services such as load balancing, and transaction management. An EJB is a component that encapsulates certain business logic and can be deployed to distributed environments. Client applications can use prewritten EJBs by using a standard lookup and invocation mechanism. They are modular by design and can be integrated into other applications on the Web.
Services can be published, located, and used over the Web. A Web Services architecture is based on three actors: Service requesters consult with service brokers to find the most suitable services. Then, service requesters bind to provided services. Web Services exchange data in XML. Read Full Essay Save. Structure of the Private Trading Exchange The fundamental concepts behind PTXs in turn fueled the development of a series of exchanges that would later serve as the foundation for different SOA strategies as well.
Figure 2 provides an illustration fo the structural differences of these varying approaches to building trading exchanges, a precursor and the foundation of Service Oriented Architectures.
The structure of Private Trading Exchanges As the foundation for the SOA architecture, the following PTXs is where many of the lessons learned in the initial definition of what would eventually become a more agile, more business centric approach to aligning it with the strategic direction of an enterprise.
The various forms of PTXs that emerged are briefly described here, and each has had a specific influence on the current state of SOA planning, implementation, and use: Independent Vertical Exchanges -- Exchanges that facilitate trade in order to make a market more efficient, and which have formed without significant investment from existing industry players.
These exchanges struggle with liquidity, and will ultimately merge with physical intermediaries or become vertically-specific Application Service Providers ASPs. Independent Horizontal Exchanges -- Exchanges that facilitate economies for a specific business process that transcends vertical industries. These exchanges struggle with domain expertise across verticals, and ultimately may become business process outsourcers to increase revenue.
Consortium Trading Exchanges -- Trade participants within an industry that join forces to make the vertical market more efficient. These exchanges struggle with consensus among members and scope. Private Trading Exchanges -- a single company that implements marketplace technology to enhance its own processes. These exchanges struggle with trust and multiple points of integration.
As the model matures, these companies will be as complex as those based on the many-to-many model of the Independent Trading Exchange ITX.
In addition, the PTX should benefit all members of the exchange, not just the deploying company. Transition Period from PTX to SOA As exchanges in general proved to be more structurally sound for order management and less agile than planned for, coupled with the fact that in many exchanges, the only factor everyone could agree on was how to complete a transaction, SOAs began to gain significant momentum.
Long-term business competitiveness and success require continual change and adaptation. Service-oriented architecture helps to solve immediate problems such as connecting to business partners, accessing legacy applications, and integrating across technology boundaries but, at a more strategic and fundamental level, SOA is about creating an it environment to support continuous business optimization.
With each new it project, applications increasingly embody your business processes which in turn make strategies only as flexible as applications.
By contrast, SOA structures it applications in line with your business processes and, as a result: SOA speeds business change.
