Realm
Realization Substrate
Mechanism families such as compute, runtimes, storage, networks, brokers, actors, and infrastructure.
Entries
Actor Systems
Actor Systems are runtimes that organize execution around addressable actor identities, message delivery, placement, isolation, and serialized handling per actor.
Application Hosts
Application Hosts are runtime containers for application code, request handling, background work, dependency management, and operational concerns.
Brokers
Brokers are concrete messaging substrates that mediate delivery between producers and consumers.
Compute
Compute is the concrete capacity that executes work: CPU, memory, processes, containers, virtual machines, functions, tasks, nodes, clusters, and other execution resources.
Consensus Protocols
Consensus Protocols are concrete protocol families that realize consensus under specified network, failure, timing, persistence, and membership assumptions.
CQRS
CQRS, command query Responsibility Segregation, is a realization pattern that separates the write side that interprets commands and persists authoritative change from the read side that answers queries by reconstituting queryable observations.
Durable Execution Engines
Durable Execution Engines are concrete runtimes or substrate mechanisms that realize durable execution.
Event Sourcing
Event sourcing is a realization pattern in which an entity's durable history is represented by committed events rather than only by current-state records.
Infrastructure
Infrastructure is the concrete operational environment that provides compute, networking, storage, deployment, security, observability, and platform services.
Network
Network is the realization substrate for interaction across link, network, transport, and application protocol boundaries.
Outbox
An outbox is a realization pattern that stores an outbound effect obligation in durable persistence, usually in the same local commit boundary as the state change that created the obligation.
Realization
Realization is the relation by which semantic roles, system structure, and operational semantics are made concrete in a substrate.
Runtimes
Runtimes are execution environments that host code and provide operational behavior.
Storage Systems
Storage Systems are concrete mechanisms for durable or semi-durable data: databases, event stores, object stores, key-value stores, logs, file systems, caches, and actor state providers.
Workflow Engines
Workflow Engines are runtimes for defining, coordinating, and operating multi-step workflows across time.
Write-Ahead Logging
Write-Ahead Logging, or WAL, is a storage recovery pattern in which durable recovery records are written before the corresponding state changes are allowed to become unrecoverable.
