Service Oriented Architecture (SOA)
SOA will dramatically change our working environments. Oracle SOA suite is the beginning of standards-based applications that are secured, managed and governed , and are spawned
by changes like Mergers & Acquisitions, regulatory compliance, and increased competition.
With this in mind, we introduce the concept of a Service Oriented Architecture (SOA).
What is SOA it is a design blueprint for applications within an enterprise.
Corporations will adopt SOA, to increase their business agility, for faster response changes, increased technology asset reuse, reduced integration expenses, reduced business risk & exposure
The ability of SOA to change, evolve, and manage business processes throughout an
enterprise is changing the way IT works. SOA is enabling IT to operate as a
business unit. Alignment and accounting for IT investments is now based on business
strategies and transactions. SOA in an enterprise will identify and highlight
business dependencies and encourages cooperation and communication between
business units and IT.
SOA uses Services. Corporate applications evolve into organized collections of what are
referred to as “business services”. Looking at these applications from a service
orientation perspective closely maps to business initiatives and processes. So a
service can be payroll, or extending credit, or adding a new customer—it’s no longer
only a technical transactional process.
A well architected SOA provides top to bottom management visibilityof existing web services, so one doesn’t go on a “scavenger hunt” for any given
application. A SOA provides for a more rapid method of distributing applications and
increased agility. By leveraging, and the reuse of existing enterprise software,
infrastructure, and networking/bandwidth, the costs of custom integration and
interoperability are lowered. Manual tasks are reduced or eliminated. Compliance
within an organization’s industry is accomplished by exposing business
processes and reducing risks. For even greater cost savings, these
business services are reusable for many different applications both within and outside
of the enterprise without costly changes.
Most corporations have started to plan and implement a SOA adoption.
