Business and IT agility should always be the primary and overarching goal of any SOA strategy. As an organization's SOA evolves, IT systems begin to mirror business processes, making it easier to map business change to system change. SOA infrastructure makes it easier to implement IT change because systems are composed of loosely-coupled business services that depend on well-defined discrete interfaces, preventing side-effects and internal dependencies that hinder component reuse.
Basic SOA models are defined by interoperable service providers and service consumers teamed with a Services Registry. BEA AquaLogic Service Registry provides a standards-based mechanism for these service consumers and service providers to interact with each other. It provides an index-of-record for all deployed services within the enterprise and the business policies that affect the runtime behavior of those services. By providing service consumers with the ability to locate and reuse services at runtime, AquaLogic Service Registry frees the service consumer from costly point-to-point connections with specific service end points that exposes the consumer to changes and failures.
In this manner, AquaLogic Service Registry is employed as the yellow pages for deployed services within an enterprise SOA and acts as the "DNS" for services at runtime. It is a comprehensive and proven UDDI registry that serves as a critical element to the maturity and success of an organization’s SOA. AquaLogic Service Registry catalogs data about deployed services and their locations and the policies that affect them, providing a central location for obtaining the information necessary to locate a service and determine what is necessary in order to interact with that service. With comprehensive support for the UDDI v3.0.2 specification, AquaLogic Service Registry:
- bridges the design-time and runtime stages of the SOA lifecycle
- enables runtime governance
- enables service infrastructure resilience
- and increases business agility
