🖧Distributed Computing

NEW

A computing model where system components run on multiple networked machines to share workload, improve scalability, and enhance performance.

DESCRIPTION

Distributed computing decomposes tasks across multiple nodes that communicate over a network, enabling horizontal scalability and fault tolerance. It powers big data frameworks (Hadoop, Spark), microservices architectures, and large-scale scientific computing via MPI. Key concerns include data locality, synchronization, consistency, and failure handling. Design choices weigh coordination overheads against throughput and latency. Effective systems employ orchestration, monitoring, and resilient communication patterns to maintain service quality.

ALTERNATIVE DEFINITIONS

IBM

Distributed computing is a model in which components of a software system are shared among multiple computers to improve efficiency and performance.

Highlights model-level sharing and performance rationale.
