INFRAVIO X-Registry Platform 6

Infravio X-Registry Platform is a software platform for SOA governance and lifecycle management. At its core is a Registry Repository, which serves as a service catalog and repository for policy and related artifacts.

Systinet Registry provides a simple and standards-based means for publishing and discovering reusable business services and SOA artifacts. Systinet Registry captures all the functional and non-functional service descriptions into a centrally managed, reliable, searchable location. Fully standards-compliant, Systinet Registry provides a highly scalable, standards-based index of services and metadata, exposing a subset of SOA information for other tools and technologies to discover in operation.

With Novell eDirectory™ as a foundation, Novell Nsure™ UDDI Server adds secure identity management capability to the UDDI standard, increasing security and manageability of Web services registries.

All SOA Software products rely on an underlying UDDIv3 Registry as a core repository and system of record for service data.  The product are all fully registry independent, leveraging the UDDIv3 standard to ensure seamless interoperability with all common registries, including products from BEA, IBM, Infravio, and Systinet.  For customer that do not have a UDDI registry, and/or are focusing on run-time governance, SOA Software bundles an embedded registry with Service Manager.
