Execution Environment

Go up to Terms and Definitions

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 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.

Generalized from software engineering, systems engineering, cloud computing, and runtime-platform usage and specialized for the Crucible architecture and operational model.

An Execution Environment may operate as a Connected Environment, Disconnected Environment, or Air-Gapped Environment.

The term does not prescribe a physical machine, virtual machine, container, cloud service, or deployment technology.

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.
