# Composable Infrastructure **Domain:** Data Center Architecture / Resource Management **Doc Type:** Technical Concept Node **Maturity:** Evolving ## Definition **Composable infrastructure** is an architecture in which compute, memory, storage and network resources can be assembled from managed pools according to workload requirements rather than remaining permanently bound to one fixed server configuration. ## Governing Variable Composition governs resource visibility and allocation: which device or host can use which capacity, through which topology and for how long. ## Material and Computational Manifestation Switching fabrics, coherent interconnects, management APIs, discovery, isolation and schedulers create the resource domain. [[wiki/CXL|CXL]] can support memory expansion and pooling; networked storage provides another form of disaggregation. ## Relation to Governance Composability increases utilization while giving the control plane greater authority over resources that local systems previously owned directly. The management layer becomes a practical allocator of computational possibility. ## Failure Modes Remote pooling can add latency, shared failure, security boundaries and management dependence. A resource that is logically available may be physically unsuitable because of topology, contention or power and thermal constraints. ## Related Ontology [[wiki/CXL|CXL]] · [[wiki/Rack-Scale Computing|Rack-Scale Computing]] · [[wiki/Control Plane|Control Plane]] · [[wiki/AI Factory|AI Factory]]
