RadiantOne Big Data Directory

The World’s First Dynamic Cluster, Elastic LDAP v3 Directory Based on Big Data Technology

An LDAP like never before, our Big Data Directory, HDAP, provides a whole new way of storing, searching, and discovering identity information. As the first fault-tolerant solution for distributed storage of identity, HDAP delivers elastic computing to the enterprise identity infrastructure. With the Big Data Directory, companies can radically scale their access and throughput, while increasing the level of security. Download our white paper on RadiantOne’s Big Data Directory.

RadiantOne Big Data Directory

An example of HDAP, a complete LDAP v3 server based on big data technology, deployed in a data cluster.

Our Big Data Directory is a complete LDAP v3 server, fully compatible at the application level with any popular implementation. Even better, it offers high availability through dynamically-extensible clusters with automated recovery and fail-over and scales linearly on both “reads” and “writes” to support hundreds of millions of users and entries, as well as complex queries.

The Big Data Directory’s unique, cluster-driven linear scalability makes a huge difference to its overall performance, providing extremely high availability, fast recovery, and support for very complex queries.

Product Use Cases

While the Big Data Directory is the default directory storage for RadiantOne FID, you can also use it in any situation where you’d deploy a directory—with significant advantages in performance and scalability:

  • Power your largest portal, Web Access Management, and federation deployments—including CA SSO (SiteMinder), ISAM, and OAM.
  • Provide an in-place replacement for your aging LDAP infrastructure, including Sun/Oracle and Novell—for a fraction of the maintenance costs.
  • Deliver quick access to contextual views containing integrated data from across your identity infrastructure to existing applications and the cloud.

Context-Aware Computing: HDAP as a High-Speed Contextual Storage

RadiantOne FID extracts all the rich user information and contextual data from diverse data stores–SQL, LDAP, and web services–and joins it to create a common, integrated view of each identity. Then HDAP, acting as a highly-scalable context server, stores these materialized views and delivers them at high speed.

Application-specific attributes can be stored at the virtualization layer, without requiring schema extensions to the underlying data stores. RadiantOne builds custom hierarchical views from the complete profiles to meet the needs of each application, so that all your applications get the identity they need, in a format they can understand. And RadiantOne’s persistent cache with auto refresh feature ensures that profile information is always available and always up to date.
