====== Execution Environment ====== [[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]] ===== Discussion ===== An Execution Environment provides the computing, operating-system, runtime, storage, networking, security, and configuration resources required to execute software. The environment may include physical machines, virtual machines, containers, cloud resources, operating-system services, runtime libraries, configuration data, secrets, and external service connections. An Execution Environment differs from a [[dido:99_annexes:annex-b-terms-and-definitions:t:target_environment|Target Environment]]. An Execution Environment identifies the resources in which software executes. A Target Environment identifies the environment selected to receive a particular build, deployment, or release. A single Execution Environment may support multiple software products, services, or workloads. A single product may also execute across multiple Execution Environments. ===== Definition ===== //environment that provides the computing, runtime, storage, networking, security, and configuration resources required to execute software// ===== Source ===== Generalized from software engineering, systems engineering, cloud computing, and runtime-platform usage and specialized for the Crucible architecture and operational model. ===== Note ===== An Execution Environment may operate as a [[dido:99_annexes:annex-b-terms-and-definitions:c:connected_environment|Connected Environment]], [[dido:99_annexes:annex-b-terms-and-definitions:d:disconnected_environment|Disconnected Environment]], or [[dido:99_annexes:annex-b-terms-and-definitions:a:air-gapped_environment|Air-Gapped Environment]]. The term does not prescribe a physical machine, virtual machine, container, cloud service, or deployment technology. ===== Example ===== A hardened virtual machine with an approved operating system, runtime libraries, network configuration, security controls, and application settings provides the Execution Environment for a deployed service. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
