Cerebro system has a modular structure, that means it consists of several loosely bound components. In general, these components are:
- Database – a central component of the system. Contains user accounts, projects, tasks, messages, access rights, etc. PostgreSQL is used as DBMS (http://www.postgresql.org).
- File storage – is a server which runs Cargador service. It is responsible for storing all Cerebro files on your disks.
- Mailing Server – sends e-mail notifications on behalf of Cerebro and processes emails received from users. Cargador service is used to perform these tasks, so mailing component is often located on the same server as the file storage.
- Web-server – it is the server with special software that allows you to access the Cerebro system directly through Web-browser (without Cerebro client module).
- Client Module – program that runs on end-user workstations, and exchanges data with server components (database, file storage).
For different types of Cerebro system deployment, composition and location of its components can vary greatly – from “cloud ” service to the fully local system.
