 +====== Centralized System ======
  
 +[[public:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]]
 +
 +===== Discussion =====
 +
 +A Centralized System concentrates primary control, processing, authoritative data, or system services within a central node or central location.
 +
 +Other nodes, clients, or components communicate with the central node to obtain the services or data provided by the system.
 +
 +A Centralized System commonly uses a [[private:99_annexes:annex-b-terms-and-definitions:c:centralized_network_topology|Centralized Network Topology]], but the system concept and the network topology remain distinct:
 +
 +  * A Centralized System describes the allocation of system authority, processing, state, and services
 +  * A Centralized Network Topology describes the arrangement and interconnection of network nodes
 +
 +The central node commonly performs functions such as:
 +
 +  * Processing requests
 +  * Maintaining authoritative data
 +  * Coordinating system behavior
 +  * Enforcing access controls
 +  * Recording transactions
 +  * Providing shared services
 +  * Managing backups and recovery
 +
 +A Centralized System differs from a [[public:99_annexes:annex-b-terms-and-definitions:d:distributed_system|Distributed System]], which allocates coordinated system behavior across multiple networked nodes.
 +
 +===== Definition =====
 +
 +//system in which primary control, processing, authoritative state, or services are concentrated within a central node or central location//
 +
 +===== Source =====
 +
 +  * DIDO Reference Architecture, Network Topology Taxonomy
 +  * Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
 +
 +===== Note =====
 +
 +A Centralized System does not require all components to reside on one physical computer.
 +
 +Clients, interfaces, storage devices, and supporting services can reside on multiple computers while the system retains centralized authority or control.
 +
 +A central node can create a single point of control and a single point of failure unless the architecture provides redundancy or failover.
 +
 +The term does not prescribe a mainframe, database technology, cloud platform, network protocol, or deployment model.
 +
 +===== Example =====
 +
 +A system uses one authoritative management server to store environment records, issue management commands, and coordinate all managed nodes.
 +
 +The clients and managed nodes reside on separate computers, but the management authority remains centralized.
