The Disadvantages of Service-Oriented Architecture | eHow

The Disadvantages of  SOA - Service-Oriented Architecture | eHow







How It Works


  • Service-oriented architecture defines the standards of a company's
    service applications. The architecture takes into consideration the
    services provided by the company and the needs of the consumer.
    Implementation of these principles requires an interface for consumers
    to request and receive their expected service.


    For example, if a student requests her grades from a university
    website, the grades would be displayed upon retrieval from the internal
    database. The student acts as a consumer, and the server retrieval of
    the grades is the service.

Advantages


  • Services are maintained in an application by a series of layers. Each
    layer acts according to its responsibilities and is only accessible by
    portions of the application and users. Layers can be individually
    designed and developed, increasing the potential for code recycling as
    well as creating more specific developer roles. As the application ages,
    each layer can be targeted for maintenance or scaled to meet
    performance requirements.

Disadvantages


  • The development of service-oriented architecture depends on the
    implementation of standards. Without standards, communication between
    applications becomes time and code intensive. Service-oriented
    architecture is not meant for applications with high data transfers,
    applications that do not require request/response implementation or
    applications with a short lifespan.
