Changes in the FRED system architecture

Since its first release, FRED has come a long way and has changed significantly. From a relatively small original project, over time it has grown to include modules related to the registry and the time has come for it to get a more significant reconstruction. There have also been shifts in the way the interface is designed, in the project management, as well as technological changes. The original method with a distinctive interface for each client gave way to more general and smaller interfaces, which each client can combine according to their needs. Similarly, we are moving towards modular source code architecture and last but not least, we are replacing Corba technology with gRPC. Another significant disadvantage for the large system is the narrow and poorly defined interdependence of individual parts, which slows down its response to new queries.
