Adapters are frequently used to integrate the Aleri server with data sources and data consumers. Adapters use the Aleri pub/sub API to connect to the Aleri server, and use the interface of the data source or data consumer to retrieve/receive data or deliver data respectively. An example would be the Aleri JMS adapter which subscribes to messages delivered via a JMS message bus and streams them into the Aleri server. A range of pre-built adapters are available from Aleri and custom adapters can be built by Aleri, by Aleri customers, or by third parties.
