- 20. Service: Technical definition A code exposes through an interface that describes a collection of operations that are network accessible using a standardized messaging protocol.
- 21. Service: Business definition Software components that can be spontaneously discovered, combined, and recombined to provide a solution to a business problem.
- 22. Microservice: Technical definition A microservice must have a single purpose and be loosely coupled in design and deployed independently of other microservices. "Micro" is a concept of scope rather than size.
- 23. Microservice: Business definition Microservices is an approach to application development in which a large application is built as a suite of modular components or services. These services are built around business capabilities.

- 31. Component: Atomic Units A component represents a process or business logic running in a container, serverless environment, or an existing runtime. A component is designed based on a specific scope, which can be independently run and reused at the runtime.
- 32. Cell: Units of Enterprise Architecture A cell is a collection of components, grouped from design and implementation into deployment. A cell is independently deployable, manageable, and observable.
