Initiatives Catering Towards Application Services Are Gaining Momentum
Most of the successful organizations of today take the Service-Oriented Architecture (SOA) approach to provide greater business agility in the face of evolving business requirements and complex, heterogeneous information technology (IT) environments.
To achieve this agility, architects implement a services abstraction that loosely couples business services from the underlying implementations of those Services.
Building such an abstraction layer is not without risks, however-inherent in building such an abstraction is the risk of sacrificing performance and scalability to achieve the organization's required agility.
As providing application services becomes mainstream, though, enterprises simply cannot afford to trade away performance to achieve agility.
As a result, architects must plan for performance up front, as part of their planning process, and leverage a variety of techniques and solutions to achieve performance and scalability as well as business agility as the traffic to their application services continues to increase.
Business agility, by definition is the ability to quickly and efficiently respond to changes in the business environment and to leverage such change for competitive advantage.
This aspect is the primary strategic motivation for most application services related initiatives.
Unlike with traditional systems engineering (TSE), where the properties of the resulting system depend upon the properties of the components that make up the system, the individual elements of a SOA implementation, including services, service compositions, application testing, policies, contracts, and the like, somehow contribute to the agility benefit, even though each of them don't exhibit business agility themselves.
In the global market of present times, commercialization of application services is causing extreme pressures on operating margin.
Clients are always demanding improved productivity, efficiency, value addition and cost reduction.
Major IT giants are now joining the SOA wagon.
Satyam for instance, has procured its very own mainframe, an IBM Z9 Business Class.
It features an extremely rich and robust software stack, and provides a platform to help application testing, development, training, and competency development, and to enhance the organization's ability to build a wide variety of proof-of-concept models.
It also aids in addressing issues, simplifying and streamlining complex interactions, and encourages focus on profitable growth, rather than system integration and maintenance.
