J2EE and Web Services Standards
There has been a significant increase in the implementation of open source software and Java development platforms. The specific revision
supported by a given server may vary, but competitive forces in the market inevitably mandate that all the offerings support the latest industry standard.
The major reasons for the increased utilization and support of J2EE and web services standards include:
| Standard |
Explanation |
Web Services and
SOA Standards Compliance |
A fundamental tenet of SOA and network-based applications is the leverage and reuse of code and business
logic across the enterprise. This is achieved through the utilization of uniform industry standards. |
|
Common
Architectural Model |
As an organization’s scale and needs change overtime, it will be necessary to migrate and redeploy applications on
different physical hardware. Sharing a common architecture, facilitates the migration of web server applications. |
|
Developer Leverage |
A
standardized application architecture provides an efficient and cost effective utilization of information technology staff in order to develop and maintain network applications. |
| Performance |
Web server and application performance are fundamental to both user satisfaction and long term efficiency and return on
investment. Performance design provides for efficient future growth with minimal new capital investment. |
| Scalability |
As an organization's information technology requirements evolve, application servers will need to scale without requiring service
disruptions or substantial redeployment efforts. Software scalability combined with savvy hardware choices can reduce energy, floor space, and operational management demands. |
| Application Infrastructure Virtualization |
In order to realize a return on investment, an organization will need its application environment to have a
comprehensive level of virtualization: server, storage, networking, and application. The dynamic allocation of application infrastructure resources will result in a better utilization of existing hardware and application
servers, reduced energy requirements, and less expenditure on additional hardware and software.

Qualifying a Training Request
Systems are developed based upon a design framework. A
service model is the separation between the interface and the
implementation. The invoker of a service needs only to understand the
interface; this allows the implementation to evolve over time without
interruption of the service to the client. The benefits of service
orientation derive from the abstraction of the delivery. The same
interface can be offered by multiple implementations; conversely the
implementations can change without affecting the application.
A service orientation views everything as a service
provider. The service model is fractal. The newly formed process is a
service itself; it exposes a new aggregated capability. Systems are
developed to contain services, which themselves are programs that can be
interacted with using well-defined message exchanges.
