Architecture
Main Components
ABBYY Recognition Server consists of 8 main components: Server Manager, Scanning Station, Processing Station,
Verification Station, Indexing Station, Remote Administration Console, COMbased API, and Web Service.
Server Manager
This is the main component. It works as a Windows service, manages licenses and all processing options, forms and
manages the job queue, distributes the jobs among Processing Stations, Verification Stations, and Indexing Stations, and
delivers the output documents after processing. It also coordinates the work of other components (Processing Stations,
Verification Stations, and Indexing Stations) and interacts with the Remote Administration Console and the Open API.
The Server Manager does not perform recognition, this task is performed by Processing Stations.
ABBYY Recognition Server will not function without the Server Manager. To run the Server Manager, you need an
activated and nonexpired license. See the Protection Technology and License Activation section for details.
Scanning Station
This component allows you to perform batch scanning and pass images to Recognition Server for further processing.
Processing Station
This component is a Windows service that directly performs recognition. It processes files received from the Server
Manager.
The Recognition Server allows you to connect several Processing Stations to one Server Manager in order to increase the
processing speed and maximize the throughput. The Server Manager will evenly distribute the workload among the
CPUs of the Processing Stations.
