(December 2020) (Learn how and when to remove this message) The landscape for instant messaging involves cross-platform instant messaging clients that can handle one or multiple protocols. [ 1 ] Clients that use the same protocol can typically federate and talk to one another.
In ADFS, identity federation [4] is established between two organizations by establishing trust between two security realms. A federation server on one side (the accounts side) authenticates the user through the standard means in Active Directory Domain Services and then issues a token containing a series of claims about the user, including their identity.

Use of identity federation standards can reduce cost by eliminating the need to scale one-off or proprietary solutions.

Federated architecture as database architecture was first introduced by Denis Heimbigner 1982 [3] and 1985 with the title: A Federated Architecture for Information Management: [4] "This federated database architecture allows a collection of database systems (components) to unite into a loosely coupled federation in order to share and exchange ...
The federations are often universities or public service organizations. The Shibboleth Internet2 middleware initiative created an architecture and open-source implementation for identity management and federated identity -based authentication and authorization (or access control ) infrastructure based on Security Assertion Markup Language (SAML).
Matrix (sometimes stylized as [matrix]) is an open standard and communication protocol for real-time communication. [2] It aims to make real-time communication work seamlessly between different service providers, in the way that standard Simple Mail Transfer Protocol email currently does for store-and-forward email service, by allowing users with accounts at one communications service provider ...
