Architecturally, the modern enterprise architecture design could involve:

  • Service Oriented
  • Event-Driven
  • Loosely coupled
  • Aligned with life cycle support processes
  • Able to support assembly and integration
  • Able to leverage existing applications and infrastructure

SOAs offer the following advantages over traditional approaches to distributed computing:

  • They offer business services across the platforms
  • They provide location independence
  • Services need not be at a particular system or particular network
  • Completely loosely coupled approach
  • Authentication and authorization support at every level
  • The search and connectivity to other services is dynamic

Short-term benefits of implementation:

  • Enhances reliability
  • Reduces hardware acquisition costs
  • Leverages existing development skills
  • Accelerates movement to standards-based server and application consolidation
  • Provides a data bridge between incompatible technologies

Long-term benefits of implementation:

  • Provides the ability to build composite applications
  • Creates a self-healing infrastructure that reduces management costs
  • Provides truly real-time decision-making applications
  • Enables the compilation of a unified taxonomy of information across an enterprise and its customer and partners

Benefits from the perspective of Business Value

  • Ability to more quickly meet customer demands
  • Lower costs associated with the acquisition and maintenance of technology
  • Management of business functionality closer to the business units
  • Leverages existing investments in technology
  • Reduces reliance on expensive custom development
