===== Discussion =====

A Platform Service is a service that supplies a shared technical capability to applications, [[dido:99_annexes:annex-b-terms-and-definitions:w:workload|Workloads]], operators, or other platform components.

A Platform Service may supply:

  * Identity
  * Authentication
  * Authorization
  * Name resolution
  * Service discovery
  * Secret management
  * Key management
  * Configuration distribution
  * Logging
  * Monitoring
  * Messaging
  * Data storage
  * Repository access
  * Policy enforcement
  * Network management

A Platform Service may operate:

  * As a [[dido:99_annexes:annex-b-terms-and-definitions:c:containerized_workload|Containerized Workload]]
  * On a [[dido:99_annexes:annex-b-terms-and-definitions:v:virtual_machine|Virtual Machine]]
  * Through a [[dido:99_annexes:annex-b-terms-and-definitions:p:provider_implementation|Provider Implementation]]
  * As part of a [[dido:99_annexes:annex-b-terms-and-definitions:k:kubernetes_cluster|Kubernetes Cluster]]
  * Within another platform realization

A Platform Service differs from an application service:

  * A Platform Service supplies a shared technical capability used by other subjects
  * An application service performs a domain or business function

The distinction depends on the architectural role assigned to the service.

A Platform Service differs from an [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_resource|Infrastructure Resource]]:

  * An Infrastructure Resource supplies an infrastructure capability
  * A Platform Service exposes a shared service capability through an operational interface

A Platform Service may depend on one or more Infrastructure Resources.

===== Note =====

A Platform Service does not by itself establish that the service is:

  * Available
  * Securely configured
  * Compliant
  * Authorized for use
  * Suitable for production operation
  * Accessible from every environment

Separate requirements govern those characteristics.

The term does not prescribe a deployment model, implementation technology, provider, interface protocol, or hosting platform.

===== Example =====

An identity service deployed within an Infrastructure Environment supplies authentication and authorization capabilities to multiple Containerized Workloads and platform components.
