SOA - Service Oriented Architecture

Ascent's goal for SOA is a worldwide mesh of collaborating services, which are published and available for invocation on the Service Bus. Adopting SOA is essential in delivering the business agility and IT flexibility promised by Web Services. These benefits are delivered not by just viewing service architecture from a technology perspective and the adoption of Web Service protocols, but require the creation of a Service Oriented Environment. Service is the important concept. Web Services are the set of protocols by which Services can be published, discovered and used in a technology neutral, standard form. SOA is not just architecture of services seen from a technology perspective, but the policies, practices, and frameworks by which we ensure the right services are provided and consumed. With SOA it is critical to implement processes that ensure that there are at least two different and separate processes-for provider and consumer. Rather than leaving developers to discover individual services and put them into context, the Business Service Bus is instead their starting point that guides them to a coherent set that has been assembled for their domain.

Advantages of Service Oriented Architecture (SOA) :

  • 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
