====== Platform Deployment ======

===== Discussion =====

Platform Deployment establishes an operational platform within a target [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environment]].

The deployed platform may comprise:

  * Operating-system components
  * Runtime components
  * Middleware
  * Container services
  * Data services
  * Messaging services
  * Identity and access services
  * Monitoring services
  * Logging services
  * Security services
  * Platform configuration
  * Supporting [[dido:99_annexes:annex-b-terms-and-definitions:a:artifact|Artifacts]]

Platform Deployment may perform activities such as:

  * Retrieving identified platform Artifacts
  * Installing platform components
  * Applying platform configuration
  * Establishing component relationships
  * Starting platform services
  * Evaluating deployment results
  * Recording the deployed platform state

Platform Deployment differs from [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_deployment|Infrastructure Deployment]]:

  * Infrastructure Deployment creates or modifies the infrastructure resources that constitute an Infrastructure Environment
  * Platform Deployment installs and configures the platform capabilities that operate on or within that Infrastructure Environment

A Platform Deployment may depend on Infrastructure Deployment, but the architecture may perform the two deployments through separate workflows or combine them within a coordinated deployment process.

Platform Deployment also differs from application deployment:

  * Platform Deployment establishes the services and runtime capabilities required to host or support applications
  * Application deployment installs and configures an application on an available platform

===== Definition =====

//deployment that installs and configures platform components and services within a target infrastructure environment//

===== Note =====

A Platform Deployment may use:

  * [[dido:99_annexes:annex-b-terms-and-definitions:m:machine_image|Machine Images]]
  * Container images
  * Installation packages
  * Configuration Artifacts
  * Deployment specifications
  * [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_deployment|Platform Deployment]] scripts
  * [[dido:99_annexes:annex-b-terms-and-definitions:b:baseline|Baselines]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:s:security_baseline|Security Baselines]]

Completion of a Platform Deployment does not by itself establish that the deployed platform satisfies its applicable [[dido:99_annexes:annex-b-terms-and-definitions:a:acceptance_criteria|Acceptance Criteria]].

The applicable requirements determine:

  * Required platform components
  * Required configuration
  * Target Infrastructure Environment
  * Permitted deployment methods
  * Required validation
  * Required records
  * Required Evidence

The term does not prescribe a particular operating system, middleware product, container platform, cloud provider, deployment tool, or implementation technology.

===== Example =====

A Platform Deployment installs and configures container orchestration, identity, logging, monitoring, messaging, and security services within a prepared Infrastructure Environment.
