A Distributed System allocates coordinated processing, state, data, or services across multiple networked nodes.
The nodes communicate through messages and cooperate to provide the behavior of the system.
A Distributed System commonly uses a Distributed Network Topology, but the system concept and the network topology remain distinct:
Characteristics of a Distributed System include:
The nodes do not need to perform identical functions. Different nodes can provide different roles while participating in the same Distributed System.
A Distributed System differs from a Centralized System, which concentrates primary control, processing, authoritative state, or services within a central node or central location.
system in which coordinated processing, state, data, or services are allocated across multiple networked nodes
A Distributed System does not require every node to hold the same data, perform the same processing, or possess equal authority.
The governing architecture determines:
A Distributed System can contain centralized components without becoming a Centralized System when those components do not hold exclusive authority over the complete system.
The term does not prescribe peer-to-peer communication, consensus algorithms, blockchain, distributed ledgers, cloud computing, or a particular network protocol.
A deployment-management system uses multiple networked nodes to execute deployment operations, collect results, and maintain coordinated environment records.
Failure of one execution node does not prevent the remaining nodes from continuing the operations permitted by the system architecture.
