Federation (information technology)


A federation is a group of computing or network providers agreeing upon standards of operation in a collective fashion.
The term may be used when describing the inter-operation of two distinct, formally disconnected, telecommunications networks that may have different internal structures. The term federated cloud refers to facilitating the interconnection of two or more geographically separate computing clouds.
The term may also be used when groups attempt to delegate collective authority of development to prevent fragmentation.
In a telecommunication interconnection, the internal modus operandi of the different systems is irrelevant to the existence of a federation.
Joining two distinct networks:
Collective authority:
In networking systems, to be federated means users are able to send messages from one network to the other. This is not the same as having a client that can operate with both networks, but interacts with both independently. For example, in 2009, Google allowed GMail users to log into their AOL Instant Messenger accounts from GMail. One could not send messages from GTalk accounts or XMPP to AIM screen names, nor vice versa. In May 2011, AIM and Gmail federated, allowing users of each network to add and communicate with each other.
