Space-Based Architecture

Kind: style

Layer: Structural Core

Record: architecture:space-based-architecture

Severity: contextual

Scope: application, scalability, distributed state

Canonical: Ontology

A convention of holding working state in a replicated in-memory space, so no central database limits scaling.

Listed in Architecture principles, after Service-Oriented Architecture and before Stated Invariant.
